Hi there, fellows HOX users,
There were several topics about HOX's poor audio quality when capturing video or recording through voice apps, but still, there weren't any solutions how to solve the lack of frequencies down below ~100-200hz.
I have experience working with sound production, recordings, so I know that these limitations are only made by software. In that case, there must be some kind of solution to improve audio recording quality and enjoy HOX at 100%.
I tried editing srs_global.cfg (found in /system/etc/soundimage) (there was a guy who tried to improve the sound of the phone's loudspeaker and he kinda managed to do it by editing the file), by changing high-pass filter frequency in every "device"
//BLOCK: (srs_hpf_0) HiPass - Device 0
//=-=-=-=-=-=-=-=-=-=-=-=-
srs_hpf_0:hipass_order = 4 // Filter Order -
srs_hpf_0:hipass_frequency = 60 // Filter Frequency -
srs_hpf_0:hipass_is32bit = 1 // Filter Precision (16bit when 0) -
srs_hpf_0:hipass_skip = 1 // Skips High Pass Filter when true - toggle

but there aren't any results.
I don't really understand the types of devices and that they do (WOWHD, TruEQ, CSHP and so on).
Maybe there is any other cfg files who process audio input, because it's the same high-pass filter when recording on internal mic and with external 3.5mm mic.
Let's try to solve this problem everybody, because, as HTC support said
HTC is not designed for capturing things in loud environments

Don't mess with HPF, REALLY DON'T!
I have been experimenting with SRS trumedia 51 and music, HPF messes up when enabled!
these settings you have posted are from SRS_global which won't really do much, install musicBox and you can get SRS working...
There is a reason why you sould not enable HPF without know what values are right, I tried this and it made a mini explosion noise (a sqeek then a loud POP) when starting audio, I highly recommed you do not mess with it. Anyways, SRS will NOT do anything with audio recording, your best place to find audio recording values are in the media_profiles.xml in /system/etc
SRS has nothing at all to do with recording audio, only to output the SRS effect.
I hope this info helps
WOWHD is SRS WOWHD, this is a sound effect which enables a true surround sound experience.
TruEQ is SRS's native EQ settings, not much to say here...
CSHP is SRS CS Headphone. Or as I would like to call it, Dolby Digital 5.1 (Because it IS the exact same effect) (CSHP is only used in srs_truemedia_51) (HTC Enhancer uses this file)
Thank's for your answer.
I can't understand, how nobody is interested in improving audio recording quality, when it's obvious that it's a software limitation thing.
We have an almost perfect phone with good camera, but we can't fully enjoy watching and LISTENING recorded videos, because some "clever" people in HTC decided that it's normal to high-pass the mic and put a compressor on it, without any gain control - in result we have a tragic audio from loud concerts and even LOUD voice conversations (where people are sceaming a little bit).
Maybe someone has a solution?
Maybe HTC will offer switching to a ****ty iphone, which has almost perfect audio recording quality (for a phone)?!

Is there any way to disable the audio zoom when recording video?
I've noticed and seen it reported that the audio becomes almost muffled when zooming in while recording a video. It would be nice to experiment with that feature toggled on/off.

There is no way to disable the audio zoom in the native camera app. I've even emailed LG support about it and they have no workaround from inside that app.
I have been experimenting with a bunch of third party camera apps in the meantime and it seems that most of them do not show this effect so it must be baked into the native camera app or something. I would recommend looking into apps like ProShot or Camera FV-5. I know for sure ProShot does not have the audio zoom effect. I'm singling out those two cameras because they have EV (exposure value) compensation right on the interface when taking pictures/video which is really helpful because this phone doesn't seem to auto-adjust the EV properly in many situations I'm in when trying to take pictures/video.

Thanks. In another forum (here: http://forum.xda-developers.com/g4/general/lg-g4-cameras-problems-t3180240), someone mentioned that when they used a 3rd party app that, while the audio zoom was no longer a factor, the sound quality at a concert was worse than with the LG G4 camera app itself. I want to film a lot of concerts, and I have until Monday to make a decision about returning my LG G4. I don't think I'll have time to test it out at a concert before Monday. Have YOU tried it at a concert with these apps? How was the sound with these apps. Was it better or worse? Do loud sounds still get distorted easily? I have hear that the LG G4 has a bad mic. Do you think so?
Should i spend the extra $150 or $200 to get the Samsung S6? There is also the Nexus 6P, but I have heard that the frame can bend easily on that camera. And as for the Samsung, it has a really bad quality speaker when you are playing stuff back.
PS: If the audio zoom is baked into the native camera app, like you said, that sounds like a SOFTware issue, right? So could a future update fix that, possibly?
Thanks.

I primarily use my phone to video concerts as well and it's way above most other android phones in that regard, imo. Now, I wouldn't necessarily say that equates to much since non-HTC android phones have been known to record garbage at concerts. I spent a lot of time trying to figure out why my old HTC One X could record concert sound so much better than any newer phone I got and I'm finally satisfied with this phone. I tried to look over some concert videos I've been to, comparing videos recorded with the native camera app and with an app like ProShot. I can't definitively say one has better sound quality than the other but it sounds like the native app tries to soften certain louder noises (this could be a good or bad thing depending on what you want and the exact sound conditions). I don't think the phone has a bad mic either but I have experienced distortion in videos, for parts of a second - nothing too long, which I don't think can't be expected when recording in such loud environments. Otherwise, my videos have been pretty distortion free. You will want to watch where your hand is around the recording mic, at the bottom of the phone though. I've had varied results when I'm not paying attention and my hand is covering or partially covering the mic.
I don't think you'll have any better results with the Samsung phone and I've never heard particularly good things about their phones recording in concert environment. These companies don't put as much effort into their audio recording capabilities like Apple, Nokia or HTC do but LG did a pretty good job with this one. Although, the iPhones record in mono (and you can absolutely distinguish between that and how this phone records in stereo) and the feedback on HTC's camera has been pretty negative so you gotta balance the good with the bad.
This is an absolute software issue since the third party camera apps don't experience the audio zoom. Ideally, LG should have provided a way to toggle the audio zoom in the camera app like they did for the LG G2. I originally posted this hoping someone went through the camera code and found a flag to toggle to control the audio zoom as well but it doesn't look like anyone has put any effort in there or that flag is not exposed in the code?
Anyway, I don't think you're gonna find a much better, or anything better, in terms of recording concerts if you want to stick with Android. If you stick with it, I would again recommend using a third party camera app like the two I previously suggested since it eliminates the audio zoom and allows for EASY EV control. Video with the phone isn't too bad when it comes to auto-EV compensation but the photos can be horrendeous, especially if you're focusing on the lead singer's face where they usually have a spotlight. I can't even count the amount of photos I've tried to take where the lead singer's face is almost completely "whited out", if that makes sense, until I found one of these apps with easy EV control. Now, whenever I recognize that happening, I turn the EV compensation down (sometimes all the way down to -2) and I get pretty good results.
Check out my instagram if you want some real examples. Keep in mind, there's a ton of compression thrown on them from IG. The ones on there from this phone will be the ones dated July of this year and later. I can guarantee the last 9 posts on there were with the ProShot app.

Completely agree with you. Wasn't aware of that problem at all, now after I came back from a football match with many videos I realized that the sound is so crap... So still they haven't fixed it because I'm on latest MM update. How do you deal with it use ProShot app?

Yeah, I accidentally used the native camera app to record part of a concert two weeks ago where I zoomed in slightly and the effect is still there after a few OS updates.
I have gotten around it since learning about the ProShot app by using that app since it does not experience the audio zoom effect if you're trying to zoom at all during the video. I would highly recommend using that specific app or you could probably use any third-party video recording apps. ProShot, in particular, lets you zoom while retaining the original audio sound and lets you control EV very easily, even while recording. This may be a lot more important to me than you since I attend many indoor concerts. I have also found that ProShot usually takes more accurately colored images than the native camera app if there's any large difference in lighting around where your photo will be (ie. in terms of an indoor concert, darkness surrounding a spotlight on the singer), without even accounting for the EV control. For other cases where the lighting is pretty consistent around where the photo will be, I've found ProShot and the native app comparable.
I have pretty much replaced the native camera app with ProShot unless I'm somewhere well lit or want to snap something quick (double-tap the volume down button with the screen off to turn on the camera app quickly) and don't particularly care how it comes out.

So do you use pro version or demo one? If you know what are the difference, does it limit something or not, thanks.
I found the problem, I told you guys, the only way to fix it is when you want to record a gigs and zooming at the same time, you have no choice to record it in PORTRAIT mode, the audio zoom is not activated when you record in portrait mode... It's LG I don't know why they have stupid ideas, it's not even fix with the LG G5, they think it's a good feature lol.
Edit : but obviously, the stereo is not good as when you shooting in landscape mode.
Edit 2 : I don't think ProShot use completely the stereo mics, the pictures are better but the sound are worst than the native camera app.
I found a workaround for this issue with the "best ever feature" of LG called Audio zoom. Just use external microphone and everything will be fine with recorded sound. No distortion, no cutting, no filters - just raw sound even if you use zoom with the official Camera app. Forget about video recording with 3-rd party apps - the sound is terrible and the zoom is not full zoom as with the original Camera app, but some low res digital video picture cropping.
You can use any external microphone you want, but since you are about to record a gig / concert for example you would like to have the smallest one, this is what I bought also from aliexpress for 2$ - Cellphone Smartphone Portable Mini Omni-Directional Mic Microphone for Recorder:

Hi guys
I don't know if already exists some specific thread to talk about this.
Last week I recorded some live songs in Italy, in the concert Roger Waters kept inside Lucca wall.
I recorded in VIDEO MANUAL MODE, so I flag HDR10 video and 24bit HIFI audio mode.
Really good live recording, considering we are speaking about a mobile phone.
How to extract the audio track, beeing sure to extract the "raw" audio track and put it in some container that I can reproduce on my high quality player?
Thank you!
Ciao!
While I'm not sure if the artist would appreciate this, I suppose if you don't reproduce it / distribute it it'd be fine.
In either case, try using a program like Goldwave. It's a great, lightweight yet powerful, free audio editing software. You should be able to import the video file and it'll isolate the audio track from it in it's original form. From there you can save it using any codec you like including FLAC.

I'm not sure I've understood the purpose of your words....no reflex camera for photo purpose or any other object, nothing of nothing were allowed and in fact nobody had any professional camera....but the phone were allowed and THOUSANDS of mobile phones (like mine) were raised above our heads to capture the event.......

What I meant was, sometimes artists don't appreciate when you record their live performances and host it online or share it or sell it, etc. I suppose if you are only creating an audio track for your personal enjoyment, then it shouldn't be an issue. People are allowed in concert venues and whatnot with phones because you can't take them away. What if there's an emergency? How would you enforce removing phones from the entire audience? Just not plausible.
Anyways, it doesn't matter. Did you try Goldwave?
I went to an electronic party last weekend so I could finally test the audio recording quality on extreme situations.
https://www.youtube.com/watch?v=nzfXQqgGZ1M
Turns out its really awful. Even my friend with a Motorola G5 have better audio quality. That is pretty disappointing for me, as I'm also a DJ and music producer so I make videos under this circunstances a lot. Also it impacts song-finder apps, as the quality is so bad that the app can't recognise the song.
Is there anything that can be done via software? Custom ROM or tweaks... Or is it a matter of the microphone (hardware) quality itself?
Btw I've already tried recording with the Open Camera App selecting the "unprocessed" audio source. Gets distorted same way.
Thanks in advance.
I confirm the existence of a similar problem for me and several people. How can this be fixed at least temporarily?

Can't really call it a "problem" since it affects all Xiaomi phones. It's just a standard quality microphone paired with bad software otimization. I did some tests and the microphone is actually capable of capturing audio with less distortion under these conditions, the problem is the processing applied to the audio isn't optimized for these situations, making it distort.
Did you have the same issues using other kernels or roms? I confirm I've been getting similar issues also

Yea I tried every rom and kernel... all the same.
If it was only at shows... could live with it. But the audio distorts even at daily things like recording messages on whatsapp when inside a vehicle (I reported this on another thread). I get really frustrated.
Same here..I participate at the lot of Trance events and simply, audio is one big bulshitt. (like at 99% of Android phones). For loud events recordings, iPhones are still the best

Exactly... I always had android, then I swiched to an iphone 6s only because of the audio I knew was good... now I finally came back to android (cause I love the OS and its variety of functions compared to iOS) and unfortunately suffering again with poor audio recording. The few android I know can handle this are the top-end Samsung (S8, S9, S10). I heard about HTC also but never got to see or test it personally.
Altough I really can't understand why manufacturers don't take this audio thing more seriously, they leave this aside like no one cared about audio quality lol

Damn, I thought I was the only with this kind of concern and this is the reason I'm currently using an iPhone 6s as my second phone just for audio recording. In my case I like to listen and play metal music with my band in a rehearsal room, so I always used my phone to record my rehearsals to see my band's progress and some other things and the best phone with a good recorder was the Mi 8 Lite until someone robbed me.
Idk why Xiaomi don't take a look to this issue, I mean, I'm not saying they have to listen to heavy metal or something like that, just realize the many scenarios the people would use the recorder app or the camera, e.g. in concerts.

Most android manufacturers lose users to Apple just because of details like this, they don't realize how important this might be for some users. I mean, take for example artists on the music world... these are influent people... and 99% of them use iPhones because of things like the audio quality.
Anyway... this conversation can go really far.
Talking about the Mi 9 SE... mostly the cause of the the bad audio quality is bad software optimization. Xiaomi could get this a lot better with just some simple updates. I've tried modifying some microphone options, turns out it can actually record with less distortion (not really perfect but better). Still a bit of the guilt is on the microphone hardware itself... its kinda cheap.
try cameramx app, set audio source to external. it worked quite well at a muse concert.
the issue is the recording volume too high which affects also whatsapp vocal messages.
somebody solved it on rooted devices by installing root volume mixer pro, set the microphone gain to -3. this wasn't tested at loud events, only on whatsapp.

I've tried using Open Camera with audio source set to unprocessed. Didn't solve it for me, got a bit less distortion but still a lot (maybe bacause the sound was really extremely loud). Will try with "external" source.
I was trying to modify the mic gain directly on the system files, but I'm gonna try that volume mixer pro thing also. Ty.

Did it make it any better?
I have the Xiaomi Mi 9 SE , i love the phone, but yes the recording quality is terrible. i downloaded the Root volume control, but when im in the path files, i dont know what changes to make.....
What is the recording mic on the camera called in the files??.......what values am i looking for??......
How many changes to i need to make.......??
I don't know ir the problem is because harware or software, but this problem doesn't happen in all Xiaomi phones, because models like Mi 9T (Pro version also) or Mi 8 records the audio clearly, also, remember that an user said that the Mi 8 Lite has a good quality of audio recording (I don't know if the NORMAL Mi 9 (not SE) records well the audio). Probably the problem is from the hardware, because phones like a big part of Redmi or other Android has a low quality mic, so the sound recorded will be poor, this problem also happens with other companies like OnePlus.
But if we want to talk in a general way, all the cellphones, including those made from Apple, ASUS, HTC or Samsung are going to lose quality in the record of concerts, very few phones like some LG are good recording specifically the audio from concerts.
I fixed a bit this problem just putting a finger up the microphone. At least it didnt clip af
Try another camera app like Cinema-FV5. I heard it improves.
Had this problem with every xiaomi I owned, only Mi 8 Lite didn't have it, so strange :\
hi, i had this problem on Redmi 3, on MI 9 SE its better, but still present. I installed CameraMX and set microphone to external and i think it helps a lot !
I cant properly Record videos when loud music is involved. The sound is way too loud and muffled.
Is there any solution to this.
On stock camera and Gcam noice cancellation is being used making it sound even worse.
I found out that in Open camera choosing "unprocessed" in sound options fixes the things a little but still
Unfortunately not really. It seems that they simply screwed up the settings for ACG (automatic gain control) and audio drivers regarding video audio recordings. Most of the Xiaomi devices suffer from that. They do not care about that. It´s such a simple and basic function for a smartphone and I´m sure that hardware used could easily handle high gain audio inputs like on concerts or festivals, but the settings and config they choose to give us simply cripples the device.
It´s a shame really. There is a camera app called Footej Camera that allows you to adjust the input gain settings for video - that could be worth a try.
Also, if you´re rooted and are experienced with modifying system files you could try to modify mixer_path files to get better results. See for example thread: https://forum.xda-developers.com/redmi-note-5-pro/help/audio-recording-lacking-bass-t3814184
