Audio file to waveform using PHP
<p>I'm looking for PHP class which will take an audio file and them return an image file of the waveform - similar effect can be seen here <a href="http://soundcloud.com/rollin-fire-cru/sets/house-house-house-house/" rel="nofollow">http://soundcloud.com/rollin-fire-cru/sets/house-house-house-house/</a></p>

<p>It should run on a linux server and accept the following audio file formats: mp3, mp4, aac, wav</p>

<p>I found an example class, but it does a very basic job

<p>Any help will be highly appreciated!</p>
