Question

I would like to know if it's possible to disable the noise reduction microphone via code.

My app plays background music that gets trim off because of this new mic. So i would like to have the background noise mic disabled while my app is open and running.

Thank you

Was it helpful?

Solution

Look in Apple's Audio Unit Properties Reference document for the kAUVoiceIOProperty_BypassVoiceProcessing and kAUVoiceIOProperty_VoiceProcessingEnableAGC properties, and how to configure and/or change them.

OTHER TIPS

The new mic should be active only during phone calls and not when your app is playing music. Are you sure this is the problem ??
