Are there any Linux tools for transcoding and syncing music directories?I encode my music to FLAC, which I keep on an external hard drive. Some time ago I transcoded this collection to OGG Vorbis, in a different directory. Since then I have added to the FLAC collection. I am looking for a tool that scans my main (FLAC) collection and transcodes any new additions into the smaller (Vorbis) collection. What I have in mind is something that worked like Unison or Rsync (but was able to ignore the fact that the files are in different formats) but also transcoded during the copy process. Are there any tools that do something like this?
