I need to delete the echo noise within my audio signal.

To create the communication channel I used AudioQueue for my app as reported in the AQRecorder class from the SpeakHere: https://github.com/robovm/apple-ios-samples/tree/master/SpeakHere/Classes

Now the problem is to delete echo with the function kAudioUnitSubType_VoiceProcessingIO as suggest in AEC ( Echo Cancellation Support ) in OSX Using AudioQueue.

How convert AudioQueue in AudioUnit? I need real code example.

  • You can't use voice processing with AudioQueues. They are too slow. You have to use Audio Units for your communication if you want voice processing. – hotpaw2 Sep 28 '17 at 23:28
  • This is already clear. For software requirements, I need to use AudioQueue. What I'm looking for, as mentioned in this post: https://stackoverflow.com/questions/15471018/aec-echo-cancellation-support-in-osx-using-audioqueue/15472761#15472761, is an example of a passage from AudioQueue to AudioUnit, which should be through a render callback function. The main reason for this request is to use echo suppression on an AudioQueue. – MD. AMT Oct 02 '17 at 09:51
