[FIX] [AOSP] Improve audio recording in video and calls

[danielh1402]

After devs changed fluencetype to fluence in build.prop for low incall volume, noise cancellation is so agressive. This fix solve distortion that you can find in your recordings.

- Tested in firmware 9.5.30
- Tested in Pixel Experience CAF and Vortex

Instructions:
- Download NoiseSuppresionMod.zip
- Reboot to recovery
- Flash NoiseSuppresionMod.zip
- Reboot to system

It MAYBE works in MIUI.

If devs want to fix it in their ROMs, they need to replace audio_platform_info and mixer_paths in /vendor/etc

Thanks to @Zile995 . He solved it in mido and helped me to do it in lavender.
Also, thanks to @letsmakecakes. He helped me to make flashable zip.

Wish I had this a couple of weeks ago when I was at Primavera Sound festival! All the audio of the videos i recorded was terrible :/
Anyway, can anyone confirm this works on stock (rooted) MIUI? Thanks!

 

[DelphinusMinor]

I flashed it but have yet to test it. Before flashing this I made a phone call and I could barely hear the person on the phone. That's odd because my hearing is amazing.

Hello to all,
Thank you for your work.
Someone knows if on Lineage Rom it works this patch?
Thank you in advance.

Thanks for the mod, it's working on Lineage but the recorded audio is quite low in terms of volume.
If it could be possible to increase it a little bit at least it would be perfect, thanks again!

Hello, i got some questions about this patch:

1. Do i need to root my device to apply it (flash it)?
2. Someone already tried on a Stock ROM with MIUI?
3. Sorry for asking this but, can someone explain thoroughly the process for applying this kind of fixes/patches?

Thank you friends.

Not necessarily, but you have to unlock it in order to have a custom recovery
2. Someone already tried on a Stock ROM with MIUI?
Not that I know of
3. Sorry for asking this but, can someone explain thoroughly the process for applying this kind of fixes/patches?
It's in the OP, as I already said you must have a custom recovery which means unlocked bootloader

Thank you friends.

@danielh1402 could make the previous file available, named lavender-aosp-audio-fix.zip This new file didn't work, but the old one worked. thank you!

Which exact changes were made on the mixer_paths and audio_platform_info files?

I'm trying to fix a similar audio issue on my Mi 9 SE, if you could tell me the changes it may help me a lot.

Thanks.

On Pixel Experience Official this is stoping the video (and sometimes closing the camera) while recording. How do i do to uninstall it?

 

[gianluca212]

On Pixel Experience doesn't work, the recorded audio is still awful. And mostly it stops the video recording.
Yesterday I was watching a video recorded with the smartphone and I noticed that the microphones are very sensitive.. maybe they're simply bad adjusted and all we need to do is to lower the gain a little bit.. I don't know. Still hoping for a V2 for this mod.

Tried on Havoc OS. Everything became much worse after flashing this "improvement", nobody could make out what I was saying.
As factory reset did not work and there is no option to uninstall the mod I had to do flashing of a new os with dalvik, cashe and data wiping.
So be aware!

 

[ls.bastos]

Thanks! This mod work fine in Lineage OS 16 for Redmi Note 6 Pro. The mic volume was very low. Now is great.

 

[RanjanJain]

Not working in Havoc 3.4. Made the situation worse. No option to uninstall it.

Doing reinstall of entire ROM now.
