Audio Conversion

[djr33]

Anyone know of an extension for PHP, or even something else on the server that isn't awful to work with, that will allow converting an audio file?
I want to have the user upload a file of a few reasonable formats, then convert to a well compressed mp3 or other common format. This should be automated and save to a folder on the server. It doesn't need to be output back to the user and could even take some time to process, if that helps.
(Basically creating an archive of recordings people make.)

Here (http://www.phpclasses.org/browse/package/3583.html) is something I ran into a little bit ago. It converts from MP3 and WMA to OGG format. While it's not really what you need, you might be able to get utility out of it.

That looks useful. However, I'm not sure all users will upload mp3/wma-- more likely they'll have wav, aiff, etc. ogg may work, but I think I want something that will play in flash.
Better than I've found searching, though.

You might have come across media-convert.com (http://media-convert.com/) in your searching, but if you didn't...it might be worth a look. They convert to and from a whole host of formats -- documents, video, audio etc...

I'm not really sure how they do it. But it might be mentioned somewhere on the internet. Another lead for you to chase down. You might try their message boards. I don't know how helpful they would be.
