Each MPEG audio frame contains either 384 (Layer 1) or 1152 (Layer 2) audio samples per channel. However, each input buffer to the encoder may contain any number of PCM samples. The size of each input buffer must be a multiple of the block alignment. The encoder caches input samples until it has enough for an MPEG audio frame.

MPEG-2 (a.k.a. H.222/H.262 as was defined by the ITU) is a standard for "the generic coding of moving pictures and associated audio information". It describes a combination of lossy video compression and lossy audio data compression methods, which permit storage and transmission of movies using currently available storage media and transmission bandwidth.
