AudioParams

Audio data format.

public class AudioParams
    {
        public int sample_rate { set; get; }
        public int channels { set; get; }
        public RAW_AUDIO_FRAME_OP_MODE_TYPE mode { set; get; }
        public int samples_per_call { set; get; }

        public AudioParams()
        {
            sample_rate = 0;
            channels = 0;
            mode = RAW_AUDIO_FRAME_OP_MODE_TYPE.RAW_AUDIO_FRAME_OP_MODE_READ_ONLY;
            samples_per_call = 0;
        }

        public AudioParams(int samplerate, int channel, RAW_AUDIO_FRAME_OP_MODE_TYPE type, int samplesPerCall)
        {
            sample_rate = samplerate;
            channels = channel;

        }
    };
You can pass the AudioParams object in the following APIs to set the audio data format for the corresponding callback:
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).

Attributes

sample_rate

  • 8000.
  • (Default) 16000.
  • 32000.
  • 44100
  • 48000
channels
The number of audio channels, which can be set as either of the following values:
  • 1: (Default) Mono.
  • 2: Stereo.
mode
The use mode of the audio data. See RAW_AUDIO_FRAME_OP_MODE_TYPE.
samples_per_call
The number of samples, such as 1024 for the media push.
