Fingerprinting Options¶
If you select a file or cluster in the left-hand side of the Picard screen and select
, Picard will invoke a program to scan the files and produce a fingerprint for each that can then be used to look up the file on MusicBrainz.MusicBrainz currently supports only AcoustID (an Open Source acoustic fingerprinting system created by Lukáš Lalinský) but has previously supported TRM and MusicID PUID.
Audio Fingerprinting
This allows you to select whether or not to enable acoustic fingerprinting within Picard. If acoustic fingerprinting is diabled then all remaining options in this tab will be locked and ignored.
Ignore existing AcoustID fingerprints
When checked, any existing AcoustID fingerprint information will not be used, and the files will be rescanned.
Fingerprint calculator
This identifies the external program on your system that will be used to calculate the AcoustID fingerprints. By default, Picard uses the Chromaprint (fpcalc) utility which is included with the Picard installation.
Picard will auto-detect the path unless you have specifically overwritten it with something different than the detected path.
will show the auto detected path as a placeholder hint in the text input, and also uses it for validating the executable. The user only needs to actually select something if auto detection does not work. If the user has selected a specific path this will be used.
API key
The key used to access the AcoustID API to lookup and submit AcoustID fingerprints. There is no cost to obtain an API key.
