As part of the Hi-Fi audio DAC, there's only 3 digital filter settings: Short, Sharp, and Slow. Is there a way to tweak one of these settings to another filter (like the "short delay slow roll-off" filter)? I'm not a huge audiophile but I used to have the HTC 10 that had this setting built in, and it completely changes the listening experience for me. If there's any solution I'd be super thankful haha.

Hello everyone,
An idea just popped in my head, what do you think:
A program that changes the device volume/volume in the music-player according the noise it picks up from the outside via the phone's mic.
For example if you sit on a bus that has a pretty loud engine the music would become louder (preferably you can define by how much, maybe by defining a maximum, or assigning each noise level an arbitrary volume which is comfortable for you) but as soon as you get off the bus and the environment is a lot quieter it would drop down to normal/other predefined.
I googled a little bit, but couldn't find anything like, that, so what do you think? I don't consider myself as a programmer, so if any developers are interested feel free to actually make the program happen, I would be more than happy to use it.
Others: opinions are welcome!
Thanks,
DOMy
Honestly I'd be interested in something like that, but only to get white noise to try and lower environmental noise: I'd like volume changing ability only for the MP3 player, to recognize actual speed and turn up/down according to that. It's a feature you can find in stock, factory default car audio system (my wife's 2005 Micra, not a full optional, has got that), battery drain wouldn't be a problem as I always plug my ppc to the car cradle when I drive.

I get the idea exactly from the car-factories, the volume changing according to the speed works great
Hey guys,
So my previous Android device, I downloaded a graphic EQ, and it just worked. Even if I was watching a movie sans headphones, I could use it to boost mid-range so that dialogue was a little louder. It didn't increase overall volume, but it did shape sound and it didn't decrease overall volume.
On my T211, I have downloaded EQs, and they work provided I am not streaming audio via bluetooth. It would kind of be cool if they worked with bluetooth speakers as well (not sure if they work with bluetooth headphones) - but the bigger annoyance for me, is that if I boost one frequency, it seems that the overall media volume declines proportionately. I don't know if it works exactly to that effect, but it is something like that; the EQ improves the sound quality quite a bit, in fairness the bass is better quality than with my previous phone (w/headphones), but the music only gets so loud. Then I turn the EQ off, and the music is noticeably louder, but the sound is flat and lower quality. It's as if there's an internal safeguard to limit overall audio output, or the power it uses, or something.
There seem to be several files in the system/etc folder which would seem to govern volume and audio effects. But I haven't figured out any more than that. Not a big deal - I own a headphone amplifier - but I have seen a tweak to improve headphone volume on the Note 2 and more generally I feel this is a worthy subject for discussion. Anybody have input? If it matters, I deleted my MusicFX.apk file and 'Music Effects' no longer appears in my settings menu (which shouldn't make a difference considering my EQs do work.
Hey guys,
I just bought a nice USB-OTG DAC for Hi-Fi sound, the Audioquest Dragonfly Red. I really like the augmented sound it delivers - although I noticed a major drawback:
The maximum sound is strongly limited due to a false recognition of the true max volume by the phone. Loudness is controlled by the phone digitally, there're no buttons on the device itself.
According to my research, it is a known issue that the device is always started with level 22 of possible 64 levels of volume. This is intended to prevent harm to one's ears. But Android phones mistake level 22 as the total maximum and don't allow to go any louder. The manufacturer says that this can only be corrected over the ROM. There IS a workaround by using 'USB audio player pro', because this app directly controls the sound output. BUT, I want to listen to Spotify and Tidal, and these apps do NOT allow sound output control.
Any ideas?
I think the problem can be fixed by disabling safe headphone volume (can be done via GravityBox, not sure if there is another method) or redictering audio using SoundAbout app.
Both methods require root privileges and in my opinion this isn't a solution you're looking for.
Just sharing my ideas.
Yeah, redirecting sound output is about what I would have guessed. I just wanted to check if there's already a working solution for non-rooted devices before rooting mine.
The thing is, that I tried a couple of USB-OTG DACs, and only the Dragonfly red is having this issue. Unfortunately it's also the best sounding one...
you can find poll on reddit.
Alright, it's working with USB audio player pro. But - one major drawback:
Although Tidal is supported, this workaround does not allow for playback of offline Tidal tracks... So still no solution that'll work in everyday life...
I spent last few hours to look for options for making the Dragonfly Red work with my Z3C. This post on Pixel 2 https://forum.xda-developers.com/pixel-2-xl/themes/pixel-2-usb-audio-control-t3704024 works perfectly to significantly increase the Red's volume, however, its interface doesn't fit properly on smaller screens (HD on Z3C).
Hi, I don't know if you have noticed, but the Xiaomi Mi 6 with the original sound recorder app has an outstanding stereo sound quality (set on music and high bitrate), like an ASMR microphone. The problem is that it looks like this can be achieved only with that app; I've tried many other recorder apps but there's no stereo recording and no such a high-quality sound. I also think this is the most underrated characteristic of this flagship. Just to clarify, I put the headphones on my phone, matching the left and right channels with the respective microphones (one on the bottom, near the Type C and one on the top, near the infrared IF), I played a song and in the meanwhile I recorded it. This is the result:

And this is the original one:

(I hope not to have problems with copyrights or something; in that case, let me know about it)
Anyway, is there any way to have the same sound quality with a different ROM? I found the MIUI recorded .apk but for some reasons, it doesn't want to install. It would be a real shame if I lost this function.
Have you tried Sony's audio recorder? https://play.google.com/store/apps/details?id=com.sonymobile.androidapp.audiorecorder
I'm using it on Pixel Experience 9, I set the quality to the highest, and it has great sound quality.
Yes, I tried it but the sound quality is way lower than the original app; also, if you select "stereo recording" there's not really a stereo sound because it will record the sound only using the microphone on the bottom of the phone.
Hi guys. I downloaded an app called Android hidden settings from the play store. I already use settings database editor as well as the hidden settings magisk module, but I saw if one thing inside this app I haven't seen anywhere else. There is a setting called Hi Fi DAC pop up. When you click on it floating window opens and it gives you the option to turn on DTS x and the hi-fi quad DAC. you can toggle the switch is regardless of whether or not you're playing music so I figured this wouldn't do anything. This is what I noticed:
When the floating window first appears, DTS is already enabled, I disabled it and toggled the DAC switch to the on position and proceeded to open my music player. From here I opened the full settings menu and clicked on the sound effects section to check if the DAC was switched on in the phones full menu and the toggle is actually still set to the on position. Figuring there would be no change in sound, I messed with the left and right channels anyway as well as the sound preset and digital filter. Before I go further I forgot to mention that I do not have headphones plugged in, I am playing music directly through the phone speaker. To my surprise, the audio quality does change and the volume is limited to 75 as if a headset was plugged in.
I opened up the Flinger Dump app to check audio output details but it is very limited to what it shows. I'm wondering if anyone with more knowledge on the topic and the proper tools could do some further testing and see what changes actually occur. I use UAPP, and its output is showing differently then flinger dump is. Could be a complete waste of time, could lead to something further...
If I have not misunderstood, what you mean is that with that app, you inadvertently activated the dac or the dts for the speaker's sound channel, right? If so, it would be amazing to be able to modify how the dac behaves without headphones. Perhaps it could be activated for the speaker, perhaps not, but what you propose is very interesting.
I'm honestly not sure. I don't believe so, but it's definitely done something and I don't have the knowledge or the software to see exactly what has changed. Basically, unless you have headphones or an auxiliary cord plugged into the phones Jack, you can't toggle the Hi-Fi DAC button to the on position as I'm sure you're fully aware of. This hidden shortcut allows it to be toggled on without anything plugged in to the headphone jack. I played some tracks thinking that there is a 99.9% chance that the audio quality wouldn't change ( or the sound wouldn't change, I don't know about quality ) but to my surprise it did change the sound. As long as the DTS:X is turned off, all of the other options had some sort of effect on the audio. The sound preset, the digital filter and the left and right channel knobs all had some sort of effect on any audio I played through the phone's internal speaker, and the volume limit changed from 100 down to 75, exactly how it would behave if headphones were plugged in.
I just need someone to help figure out exactly what this is changing, because my music app is showing 16bit and various Khz from the 300 range to over 1000...and as you can see from the screenshot the FlingerDump app is showing 24bit to 32bit and depending on the track but the KHZ remains the same.
It may be a dead end, but I figured that since there is an actual change in sound.... there may be a possibility for someone with more knowledge than me to take this and run with it and see where it leads. I removed all of my audio mods except for JamesDSP and John Fawkes DTS tuning because every other mod made my phone upsample everything from 44.1 to 48 and it was pissing me off. The results above were with USB Audio Player Pro, but I disabled bit perfect mode when I tested this out in order to avoid interference with the results.
I'm on stock android q (through fota) and out of curiosity i tried that. Nothing happened. I can tap it and nothing. The same with dts settings. Turning quad dac to small speaker for me have no sense. Idk how circuits looks, but i think system itself don't let reroute signal through dac to speaker. BUT if ypu want to check then try that.
Open terminal app and type
su -c tinymix
And look for what is on screen.
If it's state is closed then quad dac is not working. If state is hifi, then it's working.
