Detailed Description

Raw audio data.

Member Data Documentation

buffer

ByteBuffer io.agora.base.AudioFrame.buffer

The data buffer of the audio frame. When the audio frame uses a stereo channel, the data buffer is interleaved. The size of the data buffer is as follows: buffer = samples × channels × bytesPerSample.

sampleRataHz

int io.agora.base.AudioFrame.sampleRataHz

The number of samples per channel in the audio frame.

bytesPerSample

int io.agora.base.AudioFrame.bytesPerSample

The number of bytes per sample. For PCM, this parameter is generally set to 16 bits (2 bytes).

channelNums

int io.agora.base.AudioFrame.channelNums

The number of audio channels (the data are interleaved if it is stereo).

• 1: Mono.
• 2: Stereo.

samplesPerChannel

int io.agora.base.AudioFrame.samplesPerChannel

The number of samples per channel in the audio frame.

timestamp

long io.agora.base.AudioFrame.timestamp

The timestamp (ms) of the audio frame.
