Attributes
- samplesPerChannel
- The number of samples per channel in the audio frame.
- bytesPerSample
- The number of bytes per sample. For PCM, this parameter is generally set to 16 bits (2 bytes).
- channelNums
-
The number of audio channels (the data are interleaved if it is stereo).
- 1: Mono.
- 2: Stereo.
- sampleRataHz
- The number of samples per channel in the audio frame.
- 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. - timestamp
- The timestamp (ms) of the audio frame.
