MPEG-1 audio layer 1

MPEG-1 Audio Layer I, commonly abbreviated to MP1, is one of three audio codecs included in the MPEG-1 standard. While supported by most media players, the codec is considered largely outdated, and replaced by MP2 or MP3.For files only containing MP1 audio, the file extension .mp1 is used.MP1 uses a comparatively simple sub-band coding, using 32 sub-bands.
