GenPUID is a MusicIP (now known as AmpliFIND Music Services) proprietary closed source command line utility for performing music analysis and audio fingerprinting of music files. GenPUID runs under Linux, Mac OS X, and Windows.

If MusicBrainz Picard can not find a PUID for a file, it may need to be run through GenPUID to be analyzed first.

The last version of GenPUID released by MusicIP was version 1.4 on October 31, 2008.


GenPUID is not available to download from AmpliFIND, but the latest versions for each platform have been made available on the MusicBrainz ftp server.


There is a readme.txt available with the application that explains the command line arguments and provides usage instructions.

Having problems with Unicode files?
Instead of using genpuid dns-key * to scan Unicode files you will need to use genpuid dns-key -r . as a workaround.
