Converting audio formats with PHP

[Sturnoff Megantic]

I would like to allow my users to upload a large wav file and have it
converted to one of the following: a smaller wav file, an MP3, RA or
WMA.

My users have access to only large files, and it is not an option to
ask them to do the converting on their own.

I've done a little research, but can't seem to find anything on this.
Can PHP do this. Should I have PHP call an outside program? which one?
how? My server's OS is XP.

All suggestions welcome and appreciated.

Here's one option:

Google for 'command line sound file conversion'

There was a recent thread (a couple of weeks ago) that is alsmost
identical to your question, see the archives.

Why not? You could supply them with programs and instructions. If you'd
supply them with something like http://www.videolan.org/vlc/ and how to
convert using the wizard. Or even write a simple java applet using JMF
you would save lots of bandwith, diskspace and cpu time yourself.

IMHO only by calling external programs.

Or possibly through an ActiveX/OCX control.
