- (NSInteger) recordingChannel

readwritenonatomicassign

The audio channel of recording: The parameter supports the following values:

• 1: (Default) Mono.
• 2: Stereo.

  Note

  The actual recorded audio channel is related to the audio channel that you capture.

• If the captured audio is mono and recordingChannel is 2, the recorded audio is the dual-channel data that is copied from mono data, not stereo.
• If the captured audio is dual channel and recordingChannel is 1, the recorded audio is the mono data that is mixed by dual-channel data. The integration scheme also affects the final recorded audio channel. If you need to record in stereo, contact technical support.
