Hi Jean,

I've one small request -  an option on speexenc that allows you to
specify a speex file to append to, allowing you to concatenate
streams without losing quality by decoding & encoding. Ideally, it

        * Read the sampling rate, etc, from the file and use those.
        * Toggle the end of stream marker on the last frame of the file
        * Continue appending new frames from thereon.

And probably ignore/conflict with settings which would change the
whole file (eg, comments, change in input format (unless an
Ogg/speex stream can have different audio formats in the same
file?), narrow/wideband, etc).

This idea only just sprung to mind when you offered - I'm currently
using a program derived from speexenc/speexdec to simply join two or
more speex files together - but I'll happily write up a patch
against CVS in the next 2 or 3 days and send it to you, if you or
others think this useful (and not just excess bloat).

Kind regards,
