AudioParams

Audio data format.

export class AudioParams {
  
  sample_rate?: number;
  
  channels?: number;
  
  mode?: RawAudioFrameOpModeType;
  
  samples_per_call?: number;
}
The SDK sets the audio data format in the following callbacks according to AudioParams.
Attention:
  • The SDK calculates the sampling interval through the samplesPerCall, sampleRate, and channel parameters in AudioParams, and triggers the onRecordAudioFrame, onPlaybackAudioFrame, onMixedAudioFrame, and onEarMonitoringAudioFrame callbacks according to the sampling interval.
  • Sample interval (sec) = samplePerCall/(sampleRate × channel).
  • Ensure that the sample interval ≥ 0.01 (s).
