This Question is pretty much the same as this one: Convert Ogg Vorbis to MP3 with Metadata only in reverse
I want to convert all my Music Library From MP3 (some are WMA or M4A, but those can be handled manually if need be) to Ogg Vorbis, as I finally booted (in the shoe-sense) Windows from my Desktop. I've looked in the Repos and found Sound Converter and OggConvert, but Sound Converter loses all my Metadata and Ogg Converter can't batch. I've also tried mp32ogg on the commandline, but the Filenames it gives are just awful.
Does Anyone know a batch MP3 to OGG Vorbis Converter that doesn't lose Metadata or mess up filenames?
I'm using Ubuntu 9.04 and I'd prefer Free Software.
P.S. I wouldn't mind FLAC either. Anything Open Source.
