Macintosh Audio Compression/Expansion
MACE (Macintosh Audio Compression/Expansion) is a lossy, proprietary compression scheme developed by Apple Computer for their Macintosh line of computers.
Technically, it's very similar to how ADPCM works.
It offers two compression modes: 6:1 (1/6th of the original file size, 235kbps) and 3:1 (1/3rd of the original file size, 470kbps). Quality is relatively poor. It only works on 8bit streams.
Visitors are encouraged not to use this codec, for several reasons:
- There are better alternatives quality-wise (ADPCM, WavPack lossy, psychoacoustic codecs)
- Proprietary codec and closed source - E.G, on Windows platform, it can only be played in QuickTime
- Won't work on bit depths other than 8bit.
QuickTime is the only software for Windows that will play and encode MACE streams.
