Acoustic Echo Cancellation

[riosn-n]

Recording from the mic picks up audio from the phone's speaker.

It would be nice to be able to pass a flag that enables acoustic echo cancellation.

Looks like -at least for Android- the implementation would be simple:

are there any plans to add support for echo cancellation in the near future?

I am not sure, at the moment it does not have the highest priority on my TODO list.

having the same AEC issue. using the earphones is a workaround for now, but that is very inconvenient.

[vikramadityaiwnl]

import { Audio } from "expo-av";

await Audio.setAudioModeAsync({
  // other config
  playThroughEarpieceAndroid: true,
});

this is the work around i am working with right now. (no earphones used)

Turns out android VOICE_COMMUNICATION audio source supports echo cancellation and noise suppression by default
So try
const stream = new InputAudioStream( AUDIO_SOURCES.VOICE_COMMUNICATION, 44100, // Sample rate in Hz. CHANNEL_CONFIGS.MONO, AUDIO_FORMATS.PCM_16BIT, 4096, // Sampling size. );

Hi @birdofpreyru ,

Do we have any ETA on this, I need this feature badly. I am creating a feature which works like a live stream conversation mode, The issue i am facing is the device captures the ai voice coming from the speaker and sends it back again to the server as this is a live stream i am not allowed to turn of mic.

USE CASE: I am taking the chunks and sending it to socket server, The sokcet responds back with chunks and i am playing it on the Sample Player, The problem is that the ai voice which is returned from the server is playing through the speaker and gets captured on the mic which is causing a problem in live audio streaming conversation.

I will be happy if you could help.

I don't have any plans to do anything about it.
