The PCMBite class defines a set of PCM audio samples that can be played as a single unit of audio. Its samples are in 16bit short format.

If there is only one channel, then the channel's samples are stored in the left channel's buffer.

The number of samples per bite depends on the number of samples in a decodeable unit in the MPEG audio layer. For layer 1, a bite contains 384 samples, for layer 2, a bite contains 1152 samples.
