Field Documentation

◆ type

AUDIO_FRAME_TYPE agora::media::IAudioFrameObserver::AudioFrame::type

◆ samples

int agora::media::IAudioFrameObserver::AudioFrame::samples

Number of samples in the audio frame: samples = (int)samplesPerCall = (int)(sampleRate × sampleInterval)

◆ bytesPerSample

int agora::media::IAudioFrameObserver::AudioFrame::bytesPerSample

Number of bytes per audio sample. For example, each PCM audio sample usually takes up 16 bits (2 bytes).

◆ channels

int agora::media::IAudioFrameObserver::AudioFrame::channels

Number of audio channels.

  • 1: Mono
  • 2: Stereo (the data is interleaved)

◆ samplesPerSec

int agora::media::IAudioFrameObserver::AudioFrame::samplesPerSec

Audio frame sample rate: 8000, 16000, 32000, 44100, or 48000 Hz.

◆ buffer

void* agora::media::IAudioFrameObserver::AudioFrame::buffer

Audio frame data buffer. The valid data length is: samples × channels × bytesPerSample

◆ renderTimeMs

int64_t agora::media::IAudioFrameObserver::AudioFrame::renderTimeMs

Timestamp to render the audio stream.

◆ avsync_type

int agora::media::IAudioFrameObserver::AudioFrame::avsync_type
