MPEG-1 Audio Layer I
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 While supported by most media players, the codec is considered largely outdated, and replaced by MP2 or MP3.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.
