I can't find RTCAudioSink

[nhatduong]

Hello,

I am developing a feature that involves both recording and playing sound on the same device. However, when I record, the audio output from the speaker is also captured in the recording, which I do not want. I've tried different approaches with AudioSession, but none have been effective. I noticed that WebRTC might be able to handle this issue, as it can record without capturing the sound from the speaker of this device. Through my research, I found that I need an RTCAudioSink, but I couldn't find RTCAudioSink in the available versions. How can I get it?

Thanks!

Any updates on this ? @nhatduong. I need to implement AEC in my mac app, I tried this -

let engine = AVAudioEngine()
let input  = engine.inputNode
do { try input.setVoiceProcessingEnabled(true) }
catch { log("setVoiceProcessingEnabled: \(error)"); exit(1) }

from - https://developer.apple.com/documentation/avfaudio/avaudioionode/setvoiceprocessingenabled(_:)
But it just suppresses the system playback, which is still picked up by the mic recording.
