Shorten is a utility developed by Tony Robinson and SoftSound Limited www.softsound.com to convert audio files to and from a compressed format. Compression of about 50% is typical. MP3 compression is usually much greater, but unlike MP3 files, shortened files result in no loss of fidelity. Shorten for Macintosh has a graphical user interface and also contains the md5sum checksum utility which can be used to verify file integrity.
