The audio_streamer class. heres what they have in the example file, which will stream it to the browser as i understand. <?php include 'class.audio_streamer.php'; $sound = new audio_streamer('./test.mp3'); $sound->save(); ?> and heres a bit of the description, "*This class implements an alternative that takes advantage of pipes between programs that are available under Unix, Linux and other systems, to execute external audio manipulation programs. This way, the resulting audio files can be streamed directly to the user browser without any delays, and without taking too much server memory or any disk space." *-nathan
