[pulseaudio-discuss] State of the WebRTC AudioProcessing library?

[Tomaž Šolc]

Dear all,

I've been recently looking into echo cancellation with Pulse Audio. 
Unfortunately, the current module-echo-cancel doesn't work well for my 
use case. I've looked into how to improve it and found that the echo 
canceling code in the WebRTC AudioProcessing library has been copied 
from webrtc and hasn't been updated since 2016.

https://www.freedesktop.org/software/pulseaudio/webrtc-audio-processing/

On the other hand, it seems that audio processing code is very actively 
developed in the webrtc upstream.

My question is about the state of WebRTC AudioProcessing library. Has it 
been deprecated or are there any plans to keep updating the code from 
upstream? I might spend some time trying to get the latest webrtc code 
running in a Pulse Audio module. If I manage to update the library, 
would you be interested in a patch?

Thanks,
Tomaž
