  @JsonKey(name: 'sample_rate')
  final int? sampleRate;

  @JsonKey(name: 'channels')
  final int? channels;

  @JsonKey(name: 'mode')
  final RawAudioFrameOpModeType? mode;

  @JsonKey(name: 'samples_per_call')
  final int? samplesPerCall;

}

Note:

The SDK calculates the sampling interval based on the samplesPerCall, sampleRate, and channel parameters in AudioParams, and triggers the onRecordAudioFrame, onPlaybackAudioFrame, onMixedAudioFrame, and onEarMonitoringAudioFrame callbacks accordingly.
Sampling interval = samplesPerCall / (sampleRate × channel).
Make sure the sampling interval is not less than 0.01 (s).

Properties

sampleRate

Sampling rate of the data in Hz. The possible values are:

8000
16000 (default)
32000
44100
48000

channels

Number of audio channels. The possible values are:

1: Mono (default)
2: Stereo

mode

Usage mode of the data. See RawAudioFrameOpModeType.

samplesPerCall

Number of audio samples per call, typically 1024 in scenarios like media stream relay.
