AudioFrame

Raw audio data.

class AudioFrame {
  const AudioFrame(
      {this.type,
      this.samplesPerChannel,
      this.bytesPerSample,

Properties

type

Audio frame type. See AudioFrameType.

samplesPerChannel

Number of samples per channel.

bytesPerSample

Number of bytes per sample. For PCM, typically 16 bits, i.e., two bytes.

channels

Number of channels (data is interleaved if stereo).

1: Mono
2: Stereo

samplesPerSec

Number of samples per second per channel.

buffer

Audio data buffer (data is interleaved if stereo). Buffer size buffer = samples × channels × bytesPerSample.

renderTimeMs

Render timestamp of the external audio frame. You can use this timestamp to restore the audio frame order; in scenarios with video (including external video source), this parameter can be used to achieve audio-video synchronization.

avsyncType

Reserved parameter.
