FLAC and/or Vorbis ;)
Those are on the possibles list. What experience does anyone on-list have with battery portables using any open source codecs? _______________
If you archive all the music in flac, you can convert the lossless audio to any format for any player. That is what I have been doing. If i need ogg, i make stuff ogg, need mp3, i make it mp3. It all stays high quality cause of flac.
