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

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.

whats this for?

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!

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.

Thanks for the amazing work!! Nothing try in miui stock?

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?

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!

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

Not working in Havoc 3.4. Made the situation worse. No option to uninstall it.
Doing reinstall of entire ROM now.

did you find a chance to try it ?
i wonder we loose modules or not after we downgrade to 20.1 ?
also dolby still works when we upgrade back to 20.3 ?

Can it work simultaneously with Dolby digital plus?
Also do I need to install anything (AML)?

I was reading through a lot of that thread and it looks like it's still based for pie and there was a section in there saying that you have to change your build prop setting to SDK level 28 if you are on oxygen 10 and Android 10 you'll be SDK 29 so I was getting force closes and I took a big risk when do the build prop edited my SDK level 228 and went straight into a bootloop. So I had to actually do a factory reset. I then restore from twrp, but I screwed up and restored everything what I should have just done a system and data restore only because then I did a soft brick and had to use the MSM tool and start all over again at Android 9! Lol.. so I know guitardedhero was making special media files for audio library they were . so extensions... I'm going to keep digging because on Android 10 I've got ice sound working which is an Asus driver and I can even change the four configurations as well as the 11 different sound profiles fall through terminal emulator. I also have a flashable DTS 2.0

Yeah that what im concerned about to change the builprop SDK to 28 instead of that i change a code on the zip so it bypass the SDK check to able it flash on SDK 29....it was a test but apparently i didn't has any problem about a Bluetooth or anything! And there is couple people successful flash it as well but imma caught up with lastest zip and lemme see if i could mod it to work on OOS 10!and yep by default it only support Android pie only! So imma try troubleshooting as much as possible before releasing it!

Updated to latest Dolby Atmos 0.727 zip and it attached on the first page... I'll leave 0.64 zip there just in case anyone need it! And once 727 zip it work without any problem on 10.3.0 for me at least (testing on AAC,LDAC even aptx HD) but let me know

I would like to personally apologise to you for posting information that caused much frustration and inconvenience for you.
That was irresponsible of me to state workarounds to circumvent a restriction I implemented without knowing the risks that could be involved and not just taking out the restriction myself.
Thank you for sharing your experience. If I had not seen it just now, I would have still assumed such an action you took to be harmless.
I did remove this restriction many versions ago after learning that many were having success on Android 10 and the latest zip a couple hours ago seems to provide a much higher success rating and the support for existing audio mods and their effects seems to now be in place if you ever get an itch to try again without needing to do any hacky, ill-advised stuff like what I said last week.
:good:

My Bluetooth stops working after flashing. Reflash of OOS was necessary to get it back.

Question Viper 4 Android and Pixel 6 Pro

Has anyone gotten Viper 4 Android to work with the pixel 6 pro yet? If not, are there alternatives? Any guides to doing this would be appreciated! I searched but didn't find much.

Android 12 (Viper4Android)
Has anyone managed to get Viper4Android working on the latest beta of Android 12? The usual methods don't work (makes sense, since its a new OS). Just curious. I like Android 12 so far, but might roll back to 11 if I can't get Viper going...

I was referring to the method linked in Post #2 where they said they changed their kernel to permissive. The Android 12 fix file is from another thread which you started and posted the file it. You might want to add a link to your post so people know what "fix" file you are talking about since it's not in this thread, lest people might get confused about what you are talking about.

I installed by using the method I had to do for OP8T. Install Audio_Modification_Library Magisk Module (DO NOT REBOOT) -> Install Viper Magisk Module (DO NOT REBOOT) -> Open Viper App (this forces a reboot) -> Remove Audio_Modification_Library. It works great for me in apps like AIMP, but in apps like YouTubeVanced have never worked for me.

@Lughnasadh I'm not currently using the Compatibility Patch. It's mainly because last time I did on the OnePlus phones, my Bluetooth audio would get fubar'd and require a Factory Reset to fix.

Thanks to the community, the Viper4android works for me on Pixe6 PRO, BUT I am unable to activate any VIPER-DDC , Headset correction profiles loading takes no effect, tried a few I see them active but no change in sound. Previously my OnePlus 8Pro worked fine with the same version (Android 12). Does anyone experience similar issue ? Can you please try and let me know.

I don't have answer for your question, perhaps go to their Telegram group to ask for help as you may have more chance there.
I do have something for your consideration. I used V4A for longer than I can remember but it must be over 10 years. However, seems the developer has already quitted the project for quite sometime, the driver has never been updated in the past 7-8 years, we are lucky that it is still working with A12. But everything has an end, I tried it on A13 Beta and it doesn't work with it. If you search the web, you properly going to find that so far no one is able to make it work with A13. The A13 is already in beta 4 and official release could be sometime in next month, unless you are going to give up to update to A13, you better start to find something to replace V4A, my choice is JamesDSP but you may find something better suit your needs.

I prefer presets because I don't know what I'm doing. I ended up moving to PowerAmp and am usually pleased with the sound. If only the developer would enable roor features, man that would be cool.

Thanks acwcanada for the suggestion. I looked at the thread and so far may stick with Android 12 (those crazy audiophiles ) because I could not find 2 key features available in Viper4Android.
1. Headphone frequency response correction (VIPER-DDC or AutoEQ in Wavelet). This feature does not even work for me in Pixel 6 pro A12L , workaround: install wavelet and use its AutoEQ feature.
2. Dynamic System feature of Viper4Android creates bass subharmonics using reference frequencies and algorithm (selectable by choosing headphone type), so it can inject them in the music making it feel much richer and restores lack of low frequencies without "booming" effect created by other bass boosters. So far nothing in this word can beat this Viper4Andoid's feature.
Some good news folks: Viper4Android and Wavelet can be stacked and work in tandem .
Perhaps going to write James to consider the above, unless I missed it.
Cheers and thanks Team !

Question i am on A11. any way to flash a working dolby atmos?

i am on latest a11 crdroid 7.18 but i tested this module https://github.com/reiryuki/Mi-Sound-Redmi-M2012K11AC-Magisk-Module
of course i also installed miui core module.
flashing goes well but when i reboot i find the new "sound effect" menu into sound settings BUT if i touch it does not enter. forces me back into general phone settings.
audio seems a little different but imho like stock rom, no near effect like miui atmos that was wonderful.
i really need a magisk module to flash... i wanna stick to a11 rom and not a12, i hope there is a way to flash atmos on this rom

I'm not sure if this is what you're looking for, but thought it may be worth a try for you
