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.

The MUSICAM audio coding was one of 14 proposals for MPEG-1 Audio standard that was submitted to ISO in 1989. The MPEG-1 Audio standard was based on the existing MUSICAM and ASPEC audio formats. The MPEG-1 Audio standard included the three audio "layers" (encoding techniques) now known as Layer I (MP1), Layer II (MP2) and Layer III (MP3).

Compared with MPEG-1 Audio Layer 1 (MP1) or Layer 2 (MP2), it provides excellent compression of music signals. It can be used for dual channels, single channel, stereo, multichannel signals and joint stereo. This format is based on perceptual coding, and the compression algorithm brings in a compression factor of about 12. The optimization of …

MP3 (MPEG-1 Audio Layer 3), more commonly referred to as MP3, is an audio encoding format. It uses a lossy compression algorithm that is designed to greatly reduce the amount of data required to represent the audio recording, yet still sound like a faithful reproduction of the original uncompressed audio to most listeners.
