Global Variable

AVAudioSessionModeMeasurement

Specify this mode if your app is performing measurement of audio input or output.

Declaration

const AVAudioSessionMode AVAudioSessionModeMeasurement;

Discussion

This mode is intended for apps that need to minimize the amount of system-supplied signal processing to input and output signals. If recording on devices with more than one built-in microphone, the primary microphone is used.

For use with the AVAudioSessionCategoryPlayback, AVAudioSessionCategoryRecord, or AVAudioSessionCategoryPlayAndRecord audio session categories.
