Write a custom lookup script for MusicBrainz Picard

Question

I have a collection of music files (~200/batch) that I need to tag through Picard. The files have no metadata, and the fingerprinting tool is very inefficient (<50% mean accuracy).

However, the titles are like this: "(Song Name)-(Artist).(format)", and they are almost perfect. I can write a sed to extract these.

I need a way to be able to write a custom script that allows me to use the Picard's lookup feature, with the parameters I extract from sed (in-script) from the filename, and do a lookup. Is that possible?

I am looking for guidelines, but an example would be great.

As @terdon requested, more details:

• Picard has two modes of identifying a song: 1) Acoustic Fingerprinting, and 2) Lookup using existing metadata
• For some reason, the first method, ie Acoustic Fingerprinting is giving me very poor result on a certain set of songs
• However, my songs already have the correct Artist Name, Track Title in the filename, I just need to lookup the track to get Year, Cover Image etc.
• The default lookup script (internal to Picard?) is using the complete file name, which has garbage in it to do a lookup, leading to inferior results
• I would like to specify which part of the file name to use for the lookup, as I mention above.

Something like:

i="Track Name/ File Name"
$artist="sed -r 's/.../\1/'" $i
$track="sed -r 's/...\2/'" $i
lookup($i, $artist, $track)

Of course the scripting language for Picard may be different.

Answer 1

It's possible to use a script, but that's not necessary. Picard has a build-in Convert File Names to Tags for that and for a better recognition, write the tags to your files taken from your filenames.
