Good evening, everybody. Since I haven't found any thread regarding this, I am asking this myself now.
A701 (and similar tabs like a700 and a500) comes with 2 microphones, which makes stereo sound recording possible. The problem is, none of audio/video recording apps I have tried out seems to "know" how to use both microphones for stereo input. None, except default/preinstalled ACER video camera app, and ONLY while using one of the video filters, like "big eyes" e.t.c., and this is, in my opinion, really weird. I tried RecForge, Camera JB+ and some other apps, which support stereo recording (and works just fine on my xperia arc phone), but no matter which settings I used, I always end up with mono recording (mono sound in stereo file format, to be exact) as output. The fact, that native video app somehow manages to record stereo audio track along the video, makes me believe that its not some fault in my device, but some kind of software/hardware mapping sort of problem. Can somebody confirm this? Any suggestions?
Best regards!

Hi! I'm interested in buying the Desire Z, but I'm not familiar with the sound quality on A2DP headphones on Android. On WM there are settings like bitpool in the registry that can change the quality a lot, but as far as I read, there are no such settings on Android and the quality is really bad.
Is it true or is there a way to change some settings to improve quality? This is really important to me and I don't think I would be buying a phone that can't play my music properly.
My htc hero and car stereo utilizes A2DP perfectly, streaming audio to car speakers. Have not noticed any bad quality, not åk expert though

Thank you for your reply, I'm hoping that I will be able to hear it myself sometime soon and see how it sounds.
Btw, have you had any disconnects and things like that?
I tested my jabra BT320s on a desire I have access to and the A2DP was spot on, it used the handsfree function aswell without issue pausing the music then carrying on after the call etc...
Am impressed, this was with stock tmobile UK firmware aswell.
Only personal experience
I have to say that when compared to Nokia N900 the a2dp sound quality doesn't seem to be as good. The music sounds somehow thinner. To make these comparisons I have used the same media files, same nokia bh-214 handsfree and same sennheiser mx550 headphones.
I hope it is possible to somehow tweak the a2dp sound quality since i think it's all a question of a2dp audio quality settings.
It has the be said though that in contrast to nokias bluetooth implementation the android one does handle switching from music to phone calls and back quite flawlessly.

Just bought a Moto G, and am liking it. However, it seems that the only way to record stereo audio is to make a video. All of the audio-only recording apps I've tried record in mono only, even if set for stereo recording. Anyone have success in this area and can suggest an app?
Thanks
Hello,
I have a relatively severe issue with the Bluetooth audio quality on my phone. It sounds pretty much exactly like 64kbits MP3, you can especially hear it in the high frequencies. It's somehow distorted and unclear and extremely annoying as it ruins the experience totally. Everyone who heard sound over my Bluetooth devices has heard this.
The weird thing: I experienced this with both my Galaxy S5 (G900F) and my Galaxy S6 (G920F) and every single Bluetooth device that is connected to them. I tried it with my Logitech Bluetooth Audio Adapter, Denon AVR X1100W, Logitech Boombox and my car stereo Kennwood KDC-BT35U. The audio quality is always the same.
However, with my Nexus 5, my Galaxy Tab S8.4 and my Laptop, the audio quality over Bluetooth is great! Also, if I use the headphone jack on my Galaxys, it sounds just fine. I mostly use Spotify and Google Play Music, but the problem is not there since it sounds great when using a cord.
I asked the Samsung Support about this and of course they didn't know anything. They offered replacing the device but I don't think that this makes a difference since I had the same problem on my Galaxy.
Now I am asking everyone else who has the Galaxy S5 or S6, have you experienced something like this? Any solutions? It is very frustrating.
I just solved this mystery. For a long time I have been using the Mi Fitness Band, and I was wearing it all the time, so whenever that is connected to the phone the audio quality gets very bad. At least I know what it is now!
Same here!
If my Mi Band 2 is paired in the Mi Fit app, the audio quality of ANY connected bluetooth device (aux speaker, car audio etc.) is distorted (especially high sounds)
I reinsatlled the Mi Fit app, even reseted the whole phone, nothing changes. Only if I unpair the Mi Band in the mi fit app, is the bluetooth audio quality ok.
Samsung Galaxy S6 Android 6.0.1
Xiaomi Mi Band 2 firmware V1.0.1.34
Good audio quality at Bluetooth playback
Guys,
I experienced the same when i playback via Bluetooth in my car. Since i installed Poweramp beta, you can choose some different type of audio playback quality. I set mine at 24 bit playback, 192 khz. I can hear some slight difference but i think you can not expect much of it.
Second option might be Viper4android and Dolby Atmos. These will increase earsgasm at your desire.
Give it a try and report feedback!
Here is a screenshot of it.
Poweramp has unbelivable awesome effects, but it does not eliminate the base problem: miband (or any Bluetooth LE stuff?) affects the bluetooth audio transmission.

That is true and sadly a known problem of android in general. See http://www.androidauthority.com/android-wear-ruining-bluetooth-speaker-headset-sound-656300/
Solution
I might have a solution for some of you. Good luck.
Find it in my reddit post. I can't post URL's because i am new here. I only created this account for sharing the solution.

Hey XDA,
my question is related to the mics of bluetooth headsets.
Is it possible to disable them and use the one of the phone instead ? (The audio quality gets bad when calling with the bluetooth mic, I mean it should be better when disabling it).
SoundAbout doesn't work (incompatibility with Oreo ig) and other Apps don't have what i need.
Same goes to wired headphones with inline mics (since the one i use is crackling).
I'm thankful for any tries or hints on how I could make it work.
Have a nice day!:good:
Phone: LeMax2
Rom: RR 6.0.0 - Oreo 8.1.0
same problem here. I cannot find the solution.
This is just what I've been looking for.
This is how I think it goes: there's different channels where sounds goes, one is what you use for almost all media, (another one is that is used when you enable media player to play along with others or play games (not sure)), and one that where calls are. "Call mode" is what makes sound crappy and I think that microphone is related crappy sound too, because it needs more Bluetooth bandwidth to transfer mic and audio data at the same time. Reasoning behind those different channels is because I have screenrecorder which can record system sounds too, but it cannot record when phone uses Bluetooth earphones mic(when it is in "call mode"). And there's more why I think it is so: I always get notification that I'm in call even if I play pubg with microphone access enabled but don't use microphone or use live video platforms like Microsoft teams or Google meet. Also sound control is same as in normal voice call: can't really mute sound fully and if Bluetooth disconnects, it plays audio from phones speaker when in normal media player it pauses it or continues playing sound in same level as last used volume level on phone speaker.
I'm currently looking way to make audio of those "calls" go as media audio and make it use mic from phone. And also making discord channel for Android users to discuss about things like these and find useful features to make use of android much easier.
Correct if I'm wrong about anything stated earlier..
And if you have any tips where I could find more specific info on this.
I found way to make it use phones mic and thus making sound quality better
I used this "mic speaker" from play store. Unfortunately I don't yet have access to post links.
Edit: sorry, wrong call. Something happened in sound quality, but it's still crappy compared to wired earphones
Hello. I've run into a strange problem on my RN7P (running on latest stable miui 12 release). When I record a video through either the stock camera app or 3rd party camera apps, the left and right channels of the audio get summed to mono. I used to be able to get stereo audio before but suddenly this happened.
I tested the native voice recorder app and that still gives me proper stereo audio with no problem, and so the issue is definitely not with the microphones. This mono audio problem happens only when I record videos.
Is there a setting somewhere that I messed up? There are no audio settings on the stock camera app and in the 3rd party app (Open Camera), I have the audio settings set to stereo which still doesn't work.
