Commandline audio compressor, expander, equalizer


I'm running a web-radio. To add the finishing touch to the stream I would like to use a compressor witch makes the music sounds more 'dynamic'.

At this moment I create my stream on a linux box. Then the stream is send to an other computer running WinAmp (on windows). In WinAmp I use the SoundSolution 'Multi Band Audio Processor'-plugin (http://www.soundsolution.it/) WinAmp sends back the stream to the Linux shoutcast server, making it accessible for the clients.

This is a bad concept because:
- I need a windows computer
- The stream needs to get encoded twice (on the linux, and on the windows), this is just eating to much cpu-cycles.
- It's instable

So, what I would like to have:
- A command line application that reads from STDIN raw-pcm data, compresses, expand, equalize,... and sends to output to STDOUT in raw-pcm data.

Is there anything like this out there? OR Is there somone who would like to participate on on project developing like this?
