iEatBrainz is a Mac OS X MusicBrainz client, written by Jay Tuley. It performs acoustic fingerprint matching in conjunction with the MusicBrainz database. Designed to work with iTunes, it can fingerprint MP3, AAC files, or any other format playable with QuickTime, and passes metadata information to iTunes. Notably, a Universal Binary is not available, although version 1.07 and 1.08 will work on Mac OS X 10.4 or 10.5 on Intel Macs.
The software uses the older TRM acoustic fingerprinting system which is discontinued by Musicbrainz and does not work any more. The author's website currently lists this software as deprecated. A download of the universal binary is not possible either.
