This is, I guess, a more general Linux question, but as I'm working on the Pi...
Is there any program that will let me edit the metadata in (in this case) an Ogg-Vorbis file? I can use Audacity, but that involves loading (and translating) the file, just to write it out again so I can edit a typo in the artist's name! I assume there's negligible degradation in going from compressed Ogg to Audacity raw and back again, but it's slow and tedious.
I was surprised -- and pleased -- to find that 'exiftool' that I use on my photos reads the metadata, but it can't rewrite the file.[FTR, I have a project to digitize some of my old 45s, and it turns out that my early Pi B, with 'arecord' and a USB audio link works really nicely for that. The Pi, wired into other stuff, is on the other side of the room from my turntable, so I need to control the Pi from my PDA via wifi (hence can't use Audacity directly), but it's all fairly efficient.]
