I have started ripping and re-ripping my whole CD collection to FLAC, improving MusicBrainz data in the process. I use
whipper for ripping, Picard for tagging, Quod Libet for playback and ReplayGain.
Of course, this only covers playback on my computer, not on mobile devices. For that I plan to convert albums and songs "on demand" to MP3. I already have a simple script that does the conversion and the most basic tags, but it does not handle covert art (stored separately in my FLAC folders, and that I intend to embed at lower resolution in the MP3 files) and other tags.
I wonder if I could use Picard to ease the process. The idea is to convert to MP3 only keeping the core MusicBrainz ID tags (either with my standalone shell script, or a Quod Libet or Picard plugin), and let Picard to a new round of tagging / embedding covert art / naming / moving files. For that to work, however, I need different settings in Picard (different album art handling, different naming rules), and I need to be able to switch between the "MP3" settings and the "FLAC" settings easily.
Does Picard support some sort of profiles for settings? Is there a way to quickly switch settings?
