Cutting MP3s + fadein/out effect

[strange1]

I'd like PHP to automatically cut Mp3 files I'm uploaded. Let's say the first 30 seconds of each song.

Is this possible?

Also, is there a way to add a fadein/out effect to the audio file serverside?

I'm not asking for a client program like mp3cutter but a script that does the same job on my server using php.

I'm not sure about cutting mp3's but i'm pretty much sure the fading cant be done!

Well, you could use an external program, prehapse one of the ones found here
I couldn't find anything in php though I'm afraid.
