setPlaybackAudioFrameBeforeMixingParameters abstract method

Future<void> setPlaybackAudioFrameBeforeMixingParameters({
  1. required int sampleRate,
  2. required int channel,
})

Sets the format of the raw audio playback data before mixing.

The SDK triggers the onPlaybackAudioFrameBeforeMixing callback according to the sampling interval.

  • sampleRate The sample rate returned in the callback, which can be set as 8000, 16000, 32000, 44100, or 48000 Hz.
  • channel The number of audio channels. You can set the value as 1 or 2. 1: Mono. 2: Stereo.

Returns When the method call succeeds, there is no return value; when fails, the AgoraRtcException exception is thrown. You need to catch the exception and handle it accordingly.

Implementation

    {required int sampleRate, required int channel});
