numOfSamples

int io.agora.rtc.AudioFrame.numOfSamples

The number of samples.

bytesPerSample

int io.agora.rtc.AudioFrame.bytesPerSample

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

channels

int io.agora.rtc.AudioFrame.channels

The number of audio channels. If the channel uses stereo, the data is interleaved.

• 1: Mono
• 2: Stereo

samplesPerSec

int io.agora.rtc.AudioFrame.samplesPerSec

The sample rate.
