setAudioDualMonoMode

Sets the channel mode of the current audio file.

int setAudioDualMonoMode(int mode);

In stereo audio files, the left and right channels can store different audio data. You can set the channel mode to original, left, right, or mixed channel mode as needed. For example, in a KTV scenario, the left channel stores accompaniment and the right channel stores vocals. If you only want to hear the accompaniment, set the channel mode to left; if you want to hear both, set it to mixed channel mode.

Note:
  • Call this method after calling the open method.
  • This method applies only to stereo audio files.
