Ogg streams can be losslessly cut and recombined serially, certainly if you cut off the crossfade parts of each, decode, mix with crossfade, re-encode, you can do this with the only loss being in the crossfade section. I don't believe you can easily do this with vorbis regain.<br>
<br>It appears that, at least on Linux, Firefox 3.5's Ogg demuxer does not support chained bitstreams as speced, so it may be a bit early to look at these sort of tricks. Better to use a lossless codec such as FLAC for remixing.<br>

Hi,<br>
<br>
To help proliferate xiph media on the Web.<br>
I feel we need a tool that could cut vorbis and theora files<br>
without re-encoding and apply a fade-in or fade-out.<br>
<br>
There is a program for mp3 files that does this.<br>
mp3DirectCut<br>
<a href="http://mpesch3.de1.cc/mp3dc.html" target="_blank">http://mpesch3.de1.cc/mp3dc.html</a><br>
<br>
This tool makes any mp3 audio reusable.<br>
<br>
This type of editor can help web content creators express their ideas<br>
with small pieces of audio and video along with the text and images.<br>
<br>
The clips can have the same original quality and they won't start<br>
abruptly, they would fade in and fade out when they were done.<br>
<br>
This is how xiph media can become just part of the web,<br>
just part of life :)<br>
<br>
bye,<br>
Jose<br>
