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.

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.

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=3D"http://mpesch3.de1.cc/mp3dc.html" target=3D"_blank">http://mpesc=
h3.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&#39;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>
