PHP MP3 Library

[fowkswe]

Hello,

Does anyone know of a PHP library for handling MP3 files? Here is what I am trying to do:

I am trying to batch process a set of MP3 files and make 30 second sample clips from each track. Is there a library that can do this?

IF NOT

Does any one know of any cheap / free software that can do this? It would be nice if the id3 information could be used to name the files as well. But I cant be too picky.

THanks in Advance,
Billy

i think with mp3's, if you just chop the data, you can then play the chopped file.

ie if a song is 3 mins 20 secs and 4.1MB, you can get the first 2.05MB and save it as a new mp3 file, and it will play for 1 min 40.

so if you used a function to get the bit rate and quality of encoding of an mp3, you could work out how many bites would give you 30 seconds worth of music.

i think the id3 tags are placed at the front of the data, and may even be fixed length. a bit of trial and error involved, but that should get you started.

also have a look at http://sourceforge.net/projects/php-mp3/

Weekender is right, if you can find the bitrate of the file, filesize, etc. you should be able to just take the first so and so kilobytes of the file to genrate clips.
