AudioParams
Audio data format.
You can pass the AudioParams object in the following APIs to set the audio data format for the corresponding callback:
- FGetRecordAudioParams: Sets the audio data format for the FOnRecordAudioFrame callback.
- FGetPlaybackAudioParams: Sets the audio data format for the FOnPlaybackAudioFrame callback.
- FGetMixedAudioParams: Sets the audio data format for the FOnMixedAudioFrame callback.
- FGetEarMonitoringAudioParams: Sets the audio data format for the FOnEarMonitoringAudioFrame callback.
Attention:
- The SDK calculates the sampling interval through the samplesPerCall, sampleRate, and channel parameters in AudioParams, and triggers the FOnRecordAudioFrame, FOnPlaybackAudioFrame, FOnMixedAudioFrame, and FOnEarMonitoringAudioFrame callbacks according to the sampling interval.
- Sample interval (sec) = samplePerCall/(sampleRate × channel).
- Ensure that the sample interval ≥ 0.01 (s).
