TAEAE really suppress the sound of the speaker ?


I want to use TAAE because I heard that the lib suppress the sound of the speaker during a recording with the microphone and a backtrack but with my test it doesn't seem to work...

Did the lib really do that ? Did I miss something ?


  • Sounds like you're talking about the voice processing IO unit. Just set the AEAudioControllerOptionEnableInput and AEAudioControllerOptionUseVoiceProcessing bitmask options when using initWithAudioDescription:options:. Note that audio quality will be impaired; the filtering isn't perfect.

  • Nice, this is exactly what I want, I will apply some filter on the voice now to make it more... human ^^
    Thank's !
