GenPUID

genpuid is a MusicIP proprietary closed-source command-line utility for performing MusicAnalysis and Audio Fingerprinting of music files as an alternative to using the MusicIP Mixer application. If Picard cannot find a PUID for a file, it may need to be run through the mixer or genpuid applications to be analyzed first.

To get genpuid you must sign up at https://secure.musicip.com/newaccount.jsp upon which it is then available from https://secure.musicip.com/account-musicdns.jsp.
