Hi: A friend asked me a question that I was unable to answer, so I'm posting it here. Can files created by the beta4 encoder be peeled down when that becomes available, or is the ability to encode peelable files also not implemented? My friend wants to know if they should switch over now or hold off until this becomes possible.

At the time being there are no peeling tools anyway - but I am no developer so I could have missed something... bye, Maik Merten --- >8 ---- List archives: xiph.org/archives Ogg project homepage: xiph.org/ogg To unsubscribe from this list, send a message to 'vorbis-request@xiph.org' containing only the word 'unsubscribe' in the body.

hi all, i have two questions about bitrate peeling that i hope someone on this list can answer: 1) my understanding is that BP allows you to derive a lower- bitrate version of an encoded file (say 128kbps) directly from a higher-bitrate version (say 192kbps), without having to re-rip from a CD or generate an intermediate WAV file. this is potentially a huge win for those who want to archive all their CDs into high-quality Oggs, and to then use files from that same archive on their Ogg-capable portable players (don't i wish) when going to exercise, etc. is my understanding of how BP is supposed to work correct, or am i missing something? 2) is BP currently implemented? if so, how do i use it? if not, any idea as to when it will be working? thanks. -hjr --- >8 ---- List archives: xiph.org/archives Ogg project homepage: xiph.org/ogg To unsubscribe from this list, send a message to 'vorbis-request@xiph.org' containing only the word 'unsubscribe' in the body.
