Hi all,
After being pointed in the right direction by treebil, I made a tweaked srs_global.cfg file for the HTC one x. I call it AudioX and I use it with the Ir1-1.29.401.11-DUO image. Once I learn how to make a CWM installer i'll post it also.
Audio X
-Removed Tru Bass setting which was boosting 400Hz - A setting which appears to be boosting the lows in the human voice frequency range. The setting seem to be calibratied to deliver a better call output rather than for Game SFX or music.
-Easened the compressor on the music output, left it the same for the phone calls.
V 01
All enabled set to 0
V 02
Fine tweak parameters
Disable Tru Bass effect.
Hi pass lowered to 120 instead of 200
Music Limiter set to 0.100 instead of 0.250
How to use:
Find System\Etc\Soundimage\srs_global.cfg and replace with the one from Zip file. Reflash rom using CWM. CWM Installer coming soon.
WARNING: I do not take any responsibility for broken speakers etc. When I tried these edits the volume was so loud the speaker made some crackle noises. If you keep that volume level chances are you will destroy the speaker and then it will crackle even at lower volumes. The new version does have a softer limiter and the volume levels are good so I think the speaker is not in danger.
All the best

I'm not bothered by the external speaker but I know quite a few people are. It's really cool that you took so much of your time pulling this together. Fixes are what XDA is supposed to be about; not circuitous *****ing. Great example of how problems and issues should be dealt with. Solutions fix problems. Endless discussion doesn't.
I'm very interested in this - would you be able to explain a little bit more about what kind of values you changed (and how you found them in that file)?
Cheers,
Josh.
Welcome I would add stuff to my dspmanager but currently homeless crashing at friends lol

Thanks for the replies.
Treebil told me about the limiter, I only changed the values and tried it out.
I am a sound designer/composer and have also made some VST instruments (synths and effects) so it was evident that something was wrong with the speaker output since the first day I got it.
So I took a look into the config file and found very familiar values (compressor, limiter ratio, eq's, frequencies, stereo width etc) and started editing them.
Since some values where for the phone, I tried editing only the speaker output ones by comparing the values (You can tell which ones are for voice because it has a bigger compression ratio: 0.450 while the speaker has 0.250)
For example, below is the Tru Bass values, something that seems to be a Bass Enhancer:
Tru Bass Effect (Bass compressor/Enhancer). This is what gives the output that "pumping" sound in the lower regions around 400 hz:
srs_wowhd_0:wowhd_trubass_enable = 1 // TruBass Toggle - toggle
Enable or disable the effect.
srs_wowhd_0:wowhd_trubass_min = 0.000 // TruBass Min - control
Lowest effect value
srs_wowhd_0:wowhd_trubass_window = 1.000 // TruBass Window - control
Highest effect value
srs_wowhd_0:wowhd_trubass_slide = 1.000 // TruBass Slider - control
Unknown
srs_wowhd_0:wowhd_trubass_compressor = 0.250 // TruBass Compressor - Ratio
As I understand it, this setting doesn't allow the bass to go over 75% of the signal by compressing it whenever it reaches that value (75% = 0.250 out of 1). In different words, every 10 dB this value 'removes' 2.5dB so the bass has a constant volume.
srs_wowhd_0:wowhd_trubass_freq = 400 // TruBass Frequency - frequency
The bass frequency that is boosted by the Trubass effect. around 400 are the lowest frequencies of the human voice, around there also being the base for the male voice. By setting this to lower values (200) you can get a heavier bass for music instead of the hi-mid sound you get from this effect now.
srs_wowhd_0:wowhd_trubass_analysis = 200 // TruBass Analysis Size - frequency
Probably the width of the effect meaning how much of the surrounding frequncies are affected by the value. So if you set Trubass_frequncy 400 and Analysis 200, it will -probably- mean that the effect changes frequencies from 300 to 500. You can also call it width
srs_wowhd_0:wowhd_trubass_sa_enable = 1 // TruBass Split Analysis Toggle - toggle
Split analysis: probably a seperaet analysis for left and right output (?)
srs_wowhd_0:wowhd_trubass_mode = 0 // TruBass Mode - enum (Mono,Stereo)
Mono mode by default.
In the tweaked file the Trubass effect has been removed completely (at least for this version which was a quick editing). When I find out how to flash the file I will make finer edits. You can set the wowhd_trubass_compressor token to a value from 0.080 to 0.150 to get a more open tweaked compression.
Limiter - A effect that reduces the maximum output of the audio above a threshold level and then amplifies the signal back to 1. So if we have a range of 100dB and the volume goes over 75%, the limiter "cuts" everything above that level and then amplifies the 75% back to 100 dB - this is what causes the very inconsistent sound when listening to lets say metal music since it keeps on limiting too much of the signal. This is very good for voice though as it keeps a constant voice level.
srs_wowhd_0:wowhd_limiter_enable = 1 // Limiter Toggle - toggle
On/Off for the limiter.
srs_wowhd_0:wowhd_limiter_gain = 0.250 // Limiter Minimum Gain - control
Gain value: In the tweaked file the limiter is set to .100 , I wanted to remove it totally but the volume got so loud that the speaker made a couple of crackles, so I thought to leave some compression for safety reasons.
Hi pass filter: A filter that removes all frequencies below a certain level.
srs_hpf_0:hipass_order = 4 // Filter Order -
The type of the filter (?)
srs_hpf_0:hipass_frequency = 400 // Filter Frequency -
The frequency below which all frequncies will be hi-passed
In the tweaked file the Hi pass filter is lowered to 120 instead of 200. This means better explosions, more lower end.
Finaly there is also a SRS3D effect, which is probably a stereo widener:
srs_wowhd_2:wowhd_srs_enable = 1 // SRS3D Toggle - toggle
On /off switch
srs_wowhd_2:wowhd_srs_speaker = 0 // SRS3D Speaker Type - enum (Speaker,Headphone)
Speaker
srs_wowhd_2:wowhd_srs_mode = 2 // SRS3D Mode - enum (Mono,Single Speaker,Stereo,Extreme)
Single Speaker
srs_wowhd_2:wowhd_center = 0.500 // Center - control
Pan
srs_wowhd_2:wowhd_space = 0.800 // Space - control
This one is probably the width of the stereo enhancer. If you set it to 0.5 chances are you get the unaltered signal.
The problem is that there are way to many blocks of data so its very hard to tell which one exactly is the speaker, which one is the phone input, which one is the camera recording input, the speaker output when talking on the phone etc. I think that also the video recording and voice (from people calling) is affected by this tweak.
When I get some time to make an executable I can try more values and find out what the rest of the things are slowly.
One last thing I need to add is that, this limiter seems to send out a chunk of audio that has the effects applied on them and -afterwards- you change the volume with the one X buttons. So even if you set the volume to 50% you will still have the original 1.000 chunk of audio but at 50% volume with all the effects already applied on them. That means that the compressor does not "kick in" after you turn up the volume on the device, but rather sends you a compressed signal which is the same for every level. So it's a fixed compression instead of dynamic.
All the best
If you want I can pack things into a zip easy enough.
Sucks I don't have time to edit I was going to edit all these edits to my dspmanager but meh lol better for someone to do it than no one pm me if you want more sound files to edit there are a few.

Thanks, that would be great actually. I've been trying to make one but can't get it working. This is the new version btw with the following just added: (Haven't tried it yet):
Enable Tru Bass
Tweaked at 120Hz instead of 400hz.
Tru Bass compressor 0.100 instead of 0.250
SRS3D Set space to 0.5 instead of 0.800 (less phaze/cancelling issues?)
cheers
Hi again,
In case someone wants to flash one, I think that the speaker output is cleaner and less compressed in Version 0.1 ( the first post) which hasn't got the Trubass effect enabled. I've been using it the last days and am very happy with the speaker output now.
All the best
On my One eXtreme Sound Enhancer Mod I have been playing around with srs_global and making it enabled in the Music player
The first time I make SRS work i noticed that the bass was wayyy too loud so I used srs_wowhd_0:wowhd_trubass_slide to turn down the bass
mabey srs_wowhd_0:wowhd_trubass_slide is the value for the Bass volume?

@Op,
I'm not a sound expert but I must say after comparing a few times with the original settings the speaker does give a warmer sound.
Awsom, thanks!
Thanks for this!
A question slightly related, do you know which is the file that controls the in-call volumes on front speaker or back speaker?
Thanks
How are people dealing with the audio problems on the Mi Max? It is affecting the Global MIUI 7&8 and the China MIUI 8 ROM. Xiaomi has done nothing despite many complaining on the MIUI forums for months. Even the latest ROM has the same problems.
The output through the headphone jack is half the volume it should be. You can easily listen to YouTube at full volume and it's not even loud. Also the sound quality is appalling with quiet vocals and heavy bass even without using the system EQ (which crashes anyway in MIUI 7). There is also a noticeable hissing/static though headphones for a few seconds before and after a system sound plays, but listening to music doesn't have the same problem.
Considering its a standard Qualcomm DAC used in many phones its terrible what Xiaomi has done to mess up the output. My Mediatek powered phone from 2012 sounds so superior and with the Mi Max being a media consumption aimed phone it's a real poor effort.
I believe the phone is taking a low internal DAC output (caused by a bug) and amplifying it hence the distorted sound and low max volume. It's the only thing I'm extremely disappointed with and wondered how others are handling the issue?
By ditching MIUI...!?
Does the Mi Max not have these issues running CM etc?
I'm sure many are currently using MIUI and I won't be ditching it at least until the years warranty is up, also want to see what MIUI 9 is like based on Nougat.

I can confirm the low headphone volume bug exists for some media/music player apps on the miui 8 global rom. However, there's an easy workaround. Open Google play music app and play an audio file in that app. Increase the headphone volume from that app beyond the 'Warning: high volume can damage hearing' volume level. Leave the headphone volume at the highest setting. Close Google play music app. The next time you play audio in your preferred media player (other than Google play music), it should already be fixed. If you don't have Google play music, you can download it from Google Play store.

That wasn't necessary... I am well aware of all things about Mi Max from day one.
And you were asking about CM so...
I thought my new earphones were faulty when I used them in my Mi Max. I was going to give them away but then I read about sound problems on Mi Max. Both my xiaomi phones have poor sound quality, mi4 always had poor quiet sound.
The low volume has been fixed for me on g8
There's some cracking but that's sorted by clean cache in the play music app there's also a equaliser in the app settings
This is a workaround for get high volume during listening to music by using IEM/Headphone. Only work with poweramp v3 alpha build 703/704
(Please Google it for APK. It's free in Poweramp forum)
Install poweramp v3 alpha, go to setting > resampler.
Select resampler type > SoX
Resampler cutoff frequency ratio > 97% ~ 99%
Dither > Improved e-weighted noise shaping (Poweramp indicate it slow but actually it fast enough)
Tap back button and select Hi-Res Output and then turn on Wired headset/aux (it will upsampled lossy format thus higher volume and audio quality improved a little bit. Another thing is make sure the 24-bit Snapdragon DAC is activated during listening session).
WARNING: Lower the volume at 20% or lower before activating Hi-Res output during playback. Trust me you'll thanks me later xD
If you can hear distorted sound at high volume, go to replay gain (RG), set preamp for songs without RG info to -7dB. (Just to make sure the sound is not clipping).
The Mi Max audio quality is pretty good even the DAC is just an integrated DAC.
In the screenshot is DSD128 playback. Working but it was downsampled. As for 24bit/96kHz source, it will upsampled to 192kHz.
Thank you for the replies. I have tried upping to volume in Google Play Music and it did increase the volume in other apps by around 20% so it's a start and thank you for the tip but it's still not really near the quality and loudness it should be for a stock Qualcomm 652 DAC. I will give the V3 Poweramp beta trick a try. I am currently using the Poweramp Pro to listen to music and the Mi Max sounds poor.
Basically Xiaomi need to go through how MIUI is handling audio and overhaul it imo, and hopefully version 9 won't need any of these work arounds because I've never had trouble on other budget phones... or I'm off to another ROM!

If you want more loudness still, louder than what the stock MIUI 8 can give you, I suggest you install music players with a 'pre-amp'. Neutron is one of my favorites among 'audiophile' grade music players (though I like BSPlayer more due to its multimedia capabilities). You can download the trial version of 'Neutron' at Google playstore (or purchase the full version if you are satisfied with the player.) Here are screenshots of Neutron music player where the pre-amp was adjusted (above zero) so as to increase the Mi Max's maximum attainable headphone volume (without buying an external portable headphone amp). Please note that too high a pre-amp setting can cause audio clipping which results to bad sound quality.
As to sound quality, yes the Mi Max headphone sound quality is really poor out of the box (MIUI 8). I have an Audio technica ATH-M50s/LE headphones which I used to listen to FLAC music on my previous Huawei Mate 7 phone. The sound quality was just ethereal. It's like listening to live musicians. I missed the headphone sound quality on my Mate 7 [DTS enabled] using the Audio technica as my headphones and BSPlayer as my preferred player (highlights the Audio Technica's strengths). Anyway, when I changed to the Mi Max, I used the same Audio Technica headphones only to be disappointed. I found out the Mi Max can't quite match the Mate 7's music reproduction [headphone DTS enabled] using the same music player (BSPlayer) or any music player for that matter. Fortunately, the Mi Max comes with headphone settings and a built in equalizer. Did a little experimentation and came up with the following settings that managed to somehow 'resemble' what my previous Mate 7 phone was able to deliver with regard to sound quality. Please note your mileage may vary depending on the quality of the headphones you use and your preferred media or music player:
1. Set Mi sound enhancer to 'ON'. Choose 'Mi headphones'.
2. Set the equalizer as follows:
These settings should improve the Mi Max's sound quality tremendously... Well, at least from my experience --- using the same Audio technica headphones and BSPlayer music player as audio player. I've saved the custom equalizer settings above as 'Mate7' because it reminds me of the sound quality of my previous Mate 7 phone. It's not a perfect match, but at least it comes close. Please note you really need good quality over-the-ear headphones if you want to overcome the Mi Max's 'poor headphone audio' shortcomings. Alternate headphones that I have thoroughly listened to and would also highly recommend are the B&W P7 and Sennheiser Momentums. I would have bought the B&W P7 had I not auditioned the Audio Technica side-by-side it and the Sennheiser Momentums. If you are serious about audio but can't give up the Mi Max for another phone with better audio components, then the recommendations above are about as good as the Mi Max can get.

FYI, the audio quality pretty impressive with IEM (Audio Technica ATH-IM50 and Trinity Audio Engineering Delta). You feel the sound is not quite loud enough because of internal amp suck. Mi Max can't handle high impedance headphone like yours (ATH-M50X). To overcome your problem, you have to pair your Mi Max with portable amp such as fiio e11k.
btw, didnt you noticed your source is clipping too much across low freq??
Actually the 'Neutron' screenshots did not show any headphones attached. The music was played on Mi Max's loudspeakers which can't reproduce low frequency so you can't hear the clipped low frequency sounds. The recording is actually only piano, vocals and cymbals. The low frequency is from instrument feedback (low frequency hum). On my ATH-M50s/LE headphones, that volume level would have been half as much since 100% is already too loud, eliminating the low frequency clipping. I don't need an external amp for my headphones. They're loud enough for me except for some Chesky recordings.
At the end of the day we shouldn't need to do any of these fixes and tweaks to make the sound from the Mi Max reasonable, Xiaomi should fix it but it seems they have very poor customer service when it comes to feedback and bugs. This Qualcomm DAC chipset is in many phones yet they don't have sound quality and loudness issues. I don't expect perfection but the Mi Max out of the box sounds worse than by budget Mediatek powered phone from 4 years ago!
i modded the mixer_paths files to make the sound louder. My roms all include this already. You need to make sure in your build.prop that fluence is enabled by making sure there is a line that says ro.qc.sdk.audio.fluencetype=fluence and make sure the two lines persist.audio.fluence.voicecall and persist.audio.fluence.speaker are set to true. Then flash this in twrp or replace your three mixer paths files in system/etc with the ones in the zip file.

Try out Foobar2000 (available on the Play Store, free & open source) instead of Neutron & you can skip the entire default sound processing with usage of the Open SL sound output & you will find a built in DSP section mostly sufficient. I am against modifying sound picture to much & as much as I sow in GSM Arena review the output sound picture is almost perfect & thick behind iPhone 6s (I plan to buy Max now). Rest is mostly influenced by quality of sound source & used headphones. For more well use dedicated external DAC & Amp.

Would actually rather increase (in small steps) output volume
In <!-- Play Scenario --> section for headphones & speaker if I whose you.
Don't exaggerate with it!
Best regards.
I did the opposite and reduced headphone volume to get rid of the hissing. I had the same problem on the Note 3 Pro, on MIUI 8 and CM13/CM14, so it's down to how the Qualcomm mixers are configured. By reducing gain and turning off companders you're dropping the noise floor. The drawback is that headphone volume is low, so this hack only works well with low impedance IEMs like Xiaomi Pistons.
1. Get rooted, open up all mixer_path_*.xml files in /system/etc.
2. Change HPHL Volume and HPHR Volume to a low value like 2.
3. Change any Comp* Switch values to 0.
4. Change RX HPH Mode to CLS_H_HIFI
5. Reboot and enjoy.
My own solution - Use VLC. Fixes the volume problem well - after you set the Audio Output to ES

Hey guys...
ScreaMySkrillEX here.
This is an audio mod made for the redmi note 3(kenzo/Kate) which also works on mi max(hydrogen/helium) as both the devices share the same audio codec and streams.
What does my mod do?
It enables dual speaker config on your device and has two variants(htc10/stereo). And there's also a stock version which only tweaks the headphone audio output.
Htc10 version uses both earpiece and loudspeaker for audio output. The output is mono and hence earpiece acts like a mid-range booster and adds more detail to the speaker audio.
Stereo version also uses both speakers for audio output but earpiece behaves as left speaker and loudspeaker behaves as the right speaker.
Instructions.
1) Download the latest zip from the drive folder link below:
https://drive.google.com/folderview?id=0B5ratNhH-7mGU3AtTVFmekE4VG8
2)Reboot to recovery.
3)Flash shox Audio Mod zip.(while flashing the file shows that its made for kenzo/Kate. Don't worry, it will work for your device also xD)
4)Reboot.
5)Feel the shox effect!
Enjoy the music...
If you have any requests or problems, feel free to ask.
I will definitely help you.
And you guys are most welcome for your suggestions.

2)Users who need more tweaking to the audio can use Viper4Android.
3)I have included some of the best IRS samples for viper4android(according to me). So try it out if you are using viper4android for complete control over your music. Extract the zip and place the contents in viper4android/kernel directory of your internal storage.(the zip provided is not recovery flashable).
4)People who use MX player for videos can enable SW audio boost which will further increase the sound levels through speakers without any distortions..
It is recommended not to listen through speakers at full volume for longer periods.. Keep the volume low by 1 or 2 steps from the max.
5)People who think that the present max volume through headphones isn't enough can install viper4android and increase output gain to 6dB in master gate..
My personal Viper4Android settings:
Master power - on
Playback gain control - off
FET compressor - off
Viper DDC - on, set to sennheiser hd558
Spectrum extension - on, set to 1.0
Firequalizer - off
Convolver - off
Differential surround, field surround, headphone surround+, reverberation - all set to off
Dynamic system - off
Viper bass - off
Viper clarity - off
Tube sound simulator - off
AnalogX - on, set to extreme
My earphones :
1) Sennheiser cx180 street-II - daily outdoor use.
2) Skullcandy Ink'D - used rarely.
3) Sony MDR-ED12LP - used when I'm at home.
List of smartphones I own right now:
1) Xiaomi Redmi Note 3(kenzo)
2) Samsung Galaxy S(i9000)
3) Xiaomi Redmi Note 4(Mido)
4) Samsung Galaxy Note(n7000)
CHANGELOGS:-
V1 - initial release.
V1.1 - tweaked the values a bit to further remove the hissing noise as reported by @MurdererFight.(thanks bro for being the first tester and reporting me)
V1.2 - added some tweaks which will truly enable HiFi audio through DAC with the help of a magisk module..now the DAC detects the impedance of the earphone or the headphone connected.this ensures proper voltage levels through the amp for the earphones/headphones.
V1.3 - Merged surround audio mod along with hifi audio..
Enjoy stereo-like sound on your kenzo (earpiece speaker also outputs sound now xD, videos feel more alive to watch now).Thanks to @AgentBuBu for the soundmod.
I just merged his mod with mine..
V1.4 - Changed the earpiece thresholds to remove the crackling sound and readjusted both the speaker sound to the same level. Now enjoy stereo like never before on your kenzo's speakers. Thanks to @Androbots for reporting this.Also made the mod universal by making a magisk and SuperSU version..
V1.45 - Readjusted the values again for both earpiece and loudspeaker to remove distortion completely, increased audio volume through headphone jack without disturbing the quality. So, now there's a very little drop in the audio but the quality is absolute eargasm.
v1.5 - Readjusted and increased the volume of both earpiece and speaker without inducing distortions. The sound level is more than stock now.
And further pushed the volume through headphones for louder volume..Now the stereo feel is amazing..
And included biQuads support for headphones for expert users. Now you can correct the frequency response of your beloved cans, IEMs.
Link for biQuads is here:
https://forum.xda-developers.com/showpost.php?p=70194192&postcount=226
v1.6 - This time made sure to keep the audio levels same at the earpiece and loudspeaker to increase the stereo and ambience.
Very little changes to headphone volume again. Removed some unused codes. Its true stereo now. Enjoy the stereo on speakers like never before
v1.7 - Fixed the messed up headphone gain as reported by @AravindhStanley and now has 2 new versions...
1) Stereo Version - The present version which you guys are using..earpiece acts as the left speaker and loudspeaker acts as the right speaker. The speaker volume and earpiece volume is balanced
2) HTC 10 Version - The new one!!!! it is based on the new HTC 10 loudspeaker audio output.. Its mono but still uses earpiece for sound. But here the earpiece acts as a mid range and bass booster and significantly increases the detail of sound heard through speakers. Here, the loudspeaker is louder than the earpiece. The earpiece just adds detail here. So don't complain about unbalanced audio levels as its kept unbalanced.
This version removes all the audio libs to disable audio offloading to the dsp..Now the audio goes straight to the DAC untouched..
So please flash your audio mods once again after flashing the mod to get them back working.
Now biQuads is fixed by the founder @chdloc himself..So its finally working now....
I recommend all the users to try both the version and keep the ones which you like.
The link to new biQuads is here:
https://forum.xda-developers.com/showpost.php?p=70194192&postcount=226
v1.7fix - This is only for HTC 10 version...Many users would have experienced no audio from the loudspeaker after flashing v1.7(it wasn't intended to work like that). This issue has been fixed. Now enjoy audio on both earpiece and loudspeaker. Loudspeaker has louder volume than earpiece as earpiece just acts like a mid range and bass booster like before.. Enjoy the sound now..
v1.8 - Made significant changes to headphone audio....
Now the audio is decoded at 24bit 192khz..but still the output is 16bit 48khz..wait for the Poweramp to fix it or if anyone knows how to edit audioflinger please pm me...if audioflinger is hacked, 24bit 192khz audio can be made systemwide....
And enabled hardware Dolby and DTS-HPX support...
Use any of the sound mod which has support for them...you will feel a difference..
Nothing much changed in speaker audio..
Reflash your audio mods again....dirty flash
v1.9 - Rebased with the stock mixer_paths.XML and edited it from the start again..its much clean and removed useless codes from the file..
Fixed the bug - in-call voice through speakers even though the phone was in earpiece mode as reported by @AravindhStanley
Finally the mod is universal! One flashable zip for all ROMs and kernels so no hustle of magisk or su versions.
Dropped the HTC10 version as I dint see much potential in it..It will be continued only on demand..
Temporarily removed biQuads support as it requires an in-depth inspection..will include it in the next build..
V2.0 - *Fixed low audio volume on headphones as reported by many....
*Introducing a stock version, which only tweaks the headphone audio leaving the speakers untouched(stock config)
*Reincarnated the HTC10 version as requested by @mahmoudthassan
V2.1 - *added bass filter for earpiece in both htc10 and stereo version to protect the speaker..
*added a bass filter for headphones also to improve bass range which also reduces distortion..
*created an uninstaller for the mod..
V2.2 - *renamed the mod from HI-FI AUDIO PATCH to shox Audio Mod.
*finally implemented biQuads and added my sound signature to the headphone audio output.
*increased the amp volume to 16 to increase output volume.
*included patched kernels also for the mod as it is mandatory.
This is a guide for creating your own biQuads which replaces the existing ones in the mod.
As you all know, biQuads is a set of 5 IIR filters which can be used to enhance the music and also correct the frequency response of the headphones/earphones which you use.
Continue from here only if you know what sampling rate, bit width, lowpass, highpass, peak filters mean. Otherwise google those terms and learn what they are and what they do
So here's how to design your own biQuads and listen the music in your way:
1) Download biQuads flashable zip from the XDA thread here:
https://forum.xda-developers.com/android/software/reference-qualcomm-audio-codec-iir-t3093000
Thank @chdloc for this great work.
2) Flash the zip in recovery and reboot.
3) You will see an app named biQuads in the apps drawer.
4) Open the app and give it root access.
5)As I told earlier, there are biQuads numbering from 1 to 5
6)After every filter you create for every number, tap design biQuad and wait for 20-30sec. You will be redirected to another window where the app check whether the filter is designed correctly or not with a spectrum graph. After that, increase the biQuad number
7) Do the same step 6 again and again from 1 to 5 until your biQuads is ready.
8)Finally, select review filter where you get a final graph and parameters of different IIR filters.
9)Then select save and give your biQuads a name(make sure there are no spaces included in the name). Click accept and the file gets saved in the internal sdcard with the filename you specified.
10)Open the *.coeffs where * is the name you specified for the biQuads in a text editor.
11) Replace IIR2 with IIR0 wherever found and change INP1 to INP2 wherever found.
12) Finally copy everything from the file and replace the contents in the mixer paths(present in /system/etc) under path name headphones. You will find similar lines there which are my biQuads already implemented.(make sure that you file editor has root access)
13) Replace those lines perfectly and align the lines as they were. Save the file when you are done and reboot.
14) Magic.

Thanks, i'm gonna to try your mod.
Is there a way to make the earpiece speaker louder that default? On the Mi Max, mine at least, it's far quieter than the main speaker, meaning it, doesn't seem like it does much.
This also means that in Stereo mode, the left channel is far more underpowered when stereo content is playing, and it's noticeable.

Maybe htc10 version is more suitable for this device..
If you have a kernel with sound control, try increasing microphone volume.

Was the same with the HTC10 version, and I'm not sure if I have a kernel that can do that, and even if I did, how would I go about doing that?
Discovered a bug with this mod. Installing this would disable mic thus any video you record has no audio. Worse uninstalling this mod would not remove the bug. So I had to reflash ROM.

UPDATE
tried it... worked! muchos gracias!
Working but it have a bugs which video recording has no sound and it also break Hi-Res audio playback on PowerAmp alpha build 704. IEM/Headphone left channel volume sometime really quiet while right channel was too loud. I have to unplug and replug audio jack to make both channels working again.
Tested with Mi Max hydrogen 6.0.1 + Audio Technica ATH-IM50/ATH-M40X/Trinity Delta
For anyone who suffer same bugs, replace mixer_paths_wcd9326.xml and mixer_paths.xml in /system/etc and set permission to 0644
thanks for the heads up.
mine is hydrogen on GlobeROM 7.7.20 + Viper4Arise
did not loose audio on video recording.

Viper4Arise is only used to further tweak the settings that this MOD offers.
so i think its just but OK not to install Viper.
also, if you already have a 3rd-party recovery, you can easily flash this.
So in Settings - Sounds and Vibrations - Advanced sound settings - sound quality and effects, you can tweak the sound coming out of the speakers.
I've got it set like this.... It adds a bit of depth so the output isn't quite so harsh when I watch YouTube videos... But it isn't perfect (lost a lot of volume)
Has anyone else played with the equalizer? What are your settings?
This is mine
A50 paired with takstar hi1200

I prefer my mids a little bit lower than every thing else but I do have all of them up a bit with 96kbs and 32 sample rate, I don't know how to post pictures on mobile but I have (left to right) +3,+2,+2.5,+2.5, +2.5,+3,+4. But this is with a HiFi headset that allows 1136kbs so I also use Dolby Atmos Premium to upscale the audio

It's possible to significantly improve loudspeakers sound quality and fix imbalance with hidden Dolby Atmos settings.
Follow any or both steps below (good for all Oneplus 7 series).
STEP 1: Fix stereo imbalance (ROOT is required)
The top loudspeaker sounds louder and crispier than bottom (moreover, the top rattles more at high volume). This can be fixed by editing dax_sqlite3.db with any SQLite editor:
Code:
/data/vendor/dolby/dax_sqlite3.db
I used SQLite Editor app:
1. Open dax_sqlite3.db and go to "tunings".
2. Open record with "speaker_landscape_normal" and edit 2 parameters, then save.
Replace audio_optimizer_gain_l with new value:
Code:
-56,0,40,16,8,0,0,0,0,0,0,0,0,0,0,0,0,0,0,-16
Replace audio_optimizer_gain_r with new value:
Code:
-16,24,72,48,40,32,32,32,32,32,32,32,32,32,32,32,32,32,32,16
Each number separated by comma = gain in dB * 16 (i.e. "32" means "+2 db", "-16" means "-1 db").
3. (OPTIONAL - may be useless on your rom) Analogically replace the same parameters for the records "speaker_portrait_normal", "speaker_landscape_India", "speaker_portrait_India".
4. Reboot. That's it!
If something goes wrong (or you dislike new sound), just remove dax_sqlite3.db and reboot. Dolby will re-create it and return all default settings. Details about this edit:
We change overal speaker output optimization. Practically it's 20-band EQ for each physical speaker (audio_optimizer_gain_l = top).
So we reset both EQs to sound equally neutral, but keep the top speaker ~2 db lower.
STEP 2: Enable graphic EQ for speakers
You can activate dolby atmos equalizer for loudspeakers (available only for headphones by default) to get more bassy and clean sound.
If you don't have ROOT, use this DAX2 app: https://forum.xda-developers.com/oneplus-7t/how-to/dolby-atmos-equaliser-7t-hd1903-root-t4054999
You will have to disable/freeze built-in dolby tuner for full functionality (see tips also in that thread).
If you have ROOT, I recommend the method below. It relies on internal dolby app and will work in all modes (dynamic/movie/music + ringtone).
You'll need to edit sound_tuner.db with any SQLite editor:
Code:
/data/data/com.oneplus.sound.tuner/databases/sound_tuner.db
Again with SQLite Editor app:
1. Open sound_tuner.db, then go to "sound_tuner" and edit the line with "speaker_device".
2. Change values for "headphone_style_preferred" ("Intelligent style") and "audio_frequency" (EQ itself), then save changes.
headphone_style_preferred keeps value from 0 to 3 (0 - balance, 1 - warmer, etc), "0" is recommended.
audio_frequency keeps a string with each band gain in dB, separated with '#' without spaces. Recommendation for 7T:
Code:
4.4#6.5#0.0#-7.8#-6.5#-5.0#-4.5#-4.0#-3.6#-4.0
Don't use "7.0" or higher for first three bands - it will harm the speakers at high volumes.
3. To apply EQ switch current mode in Dolby Atmos settings (e.g. Music to Dynamic). That's it!
To reset EQ you can return "0#0#0#0#0#0#0#0#0#0" in "audio_frequency".

Works at least for all latest Oneplus (7 / 7 Pro / 7T).
You need to edit sound_tuner.db - dolby keeps its settings for all connected devices here.
I used MyAndroidTools for quick editing:

I have a really dumb question: where can I find that app? I searched the play store and nothing I found came up with db editing tools.
Sorry about the search failure question, this is something I'd like to do.
MyAndroidTools can be downloaded at least on Github. As i'm new user here, I cannot paste links yet. Google "MyAndroidToolsWebsite github". I used 1.6.8 release apk.
There's also "aSQLiteManager" app on the play store, it's old and quite slow, but works on my 7T. Enough for tuning the speakers once

Root is required. Works for all Oneplus 7 Series
You'll need to edit sound_tuner.db with any SQLite editor:
Code:
/data/data/com.oneplus.sound.tuner/databases/sound_tuner.db
I used MyAndroidTools for quick editing:
1. Turn Music mode for speakers in Dolby Atmos and play any favorite track looped (not necessary, but much easier to compare sound difference further).
2. In MyAndroidTools go to Database > Dolby Atmos > sound_tuner.db > sound_tuner and open the line with "speaker_device".
3. Change values for "headphone_style_preferred" ("Intelligent style") и "audio_frequency" (10-band EQ), then save changes.
headphone_style_preferred keeps value from 0 to 3 (0 - balance, 1 - warmer, etc), i prefer "0".
audio_frequency keeps a string with each band gain, separated with '#' without spaces.
For 7T try this (more bassy and clean sound, but little loss in volume):
Code:
[B]2.5#6.8#0.0[/B]#-8.0#-6.0#-5.0#-4.5#-4.0#-3.8#-4.0
Don't use "7.0" or higher for first three bands - it brings distortion at high volumes.
4. To apply EQ switch to dolby atmos and change Music mode to Dynamic, and then back to Music. That's it!
To reset EQ you can return "0#0#0#0#0#0#0#0#0#0" in "audio_frequency".
Speaker EQ settings don't affect any headphones, work in all modes (dynamic/movie/music, also in ringtone mode)

Also, also preset audio_frequency for car speakers for heavy bass? Thank you! this is great!

It can harm at max volumes, mostly the top speaker. If you constantly use max volume or close, better keep first three bands under "6.0" and turn off "Intelligent EQ" (set it to "3"), as any iEQ enables additional bass boost for speakers.
My goal was great clear sound at low-to-mid volumes.
I was searching for the possibility to enable EQ on 7t without root, but nothing really worked, until I found Dolby Atmos DAX2 app (originaly from Razer phone)... (you can find it on apkmirror - I cannot share links yet...) works pretty well... maybe someone can have a use for it too...

Great finding, thanks! I checked it too and it works
This DAX2 app doesn't sync with built-in Oneplus sound tuner though (7T at least). Any change under "Settings -> Sound & vibration -> Dolby Atmos" and EQ for any device will be overrided.
It seems Oneplus has 2-way atmos audio library access - via standard SoundTuner app (in "Settings") and Dolby itself (which can be tuned by this DAX2 app).
I updated the first post - how to fix loudspeakers imbalance and improve total quality.
Try it, now Oneplus 7T sounds perfectly

Thanks for the awesome work. Anyone planning on making a magisk module or something simple for those of us not as inclined to flash all this code?
Hope too, i'm not into magisk much...
A thing about step 2 - this file is personal and keeps your headphone profiles too. Unless magisk module can change (not replace) *db file, you will have to re-tune all profiles again.
Upd: I removed attached file for replacing original db. Seemed to work incorrect even on my device (dolby turned off any effect). Manual editing still works fine.
Hey! I remember back then you posted a value set that produced great bass. Could you post that again? Thanks!

Hey! Before finding dax3_sqlite.db i used almost the same set for global EQ (now this is "step 2"):
Code:
2.5#6.8#0.0#-8.0#-6.5#-5.0#-4.6#-4.2#-4.0#-4.2
A value set i like most now in combination with additional "step 1" is updated in the first post.
You can visually and faster adjust EQ with Dax2 app in this post (then copy its values to "step 2" and remove the app):
https://forum.xda-developers.com/oneplus-7t/how-to/dolby-atmos-equaliser-7t-hd1903-root-t4054999
Thanks for the guide, my speakers sound really nice now. I have a few questions. May I know how you got the values for the speaker balancing? Not planning on doing it myself or anything, just curious. Also, with your EQ values, what are the odds of damaging the speakers at max volume?
Thanks for feedback, I also loved more 7T speakers, though sound got a little quieter.
Terrigible said:

Click to expand...
Click to collapse
The stock top speaker is louder (not much, but noticeably), GSMArena also mentioned that. Stock EQ values ("Step 1") remind me random earthquake graph, for example bottom speaker gains:
-219,-16,68,-16,-16,0,9,-11,9,-16,52,9,32,-16,-46,4,-11,12,38,-16
So I reset them all to neutral ("0"), add little bass except lowest/highest bands (speakers can't produce 46/20000 Hz). Then made bottom value set +32 higher ("+2 db"), it sounds ok for total balance (no precise measurements with mic). After I adjust global EQ based on this neutral setup ("Step 2").
Curious can also find more hidden fields to tune like bass boost, headphone optimization in the "dax_sqlite3.db".
Terrigible said:

Click to collapse
Good odds with extreme gains and constant max volume. I mean "step 2" (global EQ), no harm with "step 1" only.
On my experience all gains below +6 db are save, no distortion. One can decrease this to +4...5 db for sure safety.
Thanks for this man, now my 7t speaker sounds correct.
Anyway would you please share your EQ settings for Headphone?
