Shorten has two basic modes of operation:
- lossless: The decompressed file is exactly the same as the original. Typically a factor of two compression is obtained for 16 bit audio.
- lossy: The compression may be specified either in terms of an average number of bits per sample, or in terms of an acceptable (perceptually weighted) signal to noise ratio. Good quality is obtained at compression rates from 3:1 to 5:1 and thus it can be a good alternative to ADPCM.
Technical documentation is available.
Shorten for Windows and MSDOS may be purchased from Buyonet.com
Two evaluation versions are also available:
Shorten for Windows 16 bit evaluation
