Route voice buffer from mic to speaker in Android

Question

I need to increase voice, recorder from microphone on Android device. I try to read buffer from AudioRecord and then write it to AudioTrack... It works, but with delay, because min buffer size, returned bu method AudioRecord.getMinBufferSize with frequency like 44100 is 4480 bytes.

Any ideas?
Thanks.

Answer 1

I have this code

AudioRecord and AudioTrack latency

But it happens to that there is a 20ms delay, and I need to solve it, The code above seems that plays something but there is no mic input, does it work?

Thanks!
