Folks,
Here is a typical code snippet for loopback audio. In this code, I have
added acoustic echo canceler. I have also condensed the code for brevity.
AudioRecord recorder = new AudioRecord(...);AcousticEchoCanceler aec =
AcousticEchoCanceler.create(recorder.getAudioSessionId());
aec.setEnabled(true);
AudioTrack player = new AudioTrack(...);
...while(isRecording) {
recorder.read(data...);
player.write(data...);}
However, this code does not get rid of the echo. I am wondering if there is
something that I am missing.
What I don't understand is how aec can correlate the recorder and the
player. The aec object here has the audio session id of the recorder but it
does not have the audio session id of the player. Shouldn't there be some
way to inform aec about player's audio session id? Or, perhaps the player
can be forced to share the same audio session id.
I would appreciate any help you can provide.
Thank you in advance for your help.
Regards,
Peter
