Flash Pixel Bender: Number Crunching for Audio Processing

I've seen some example of using a Pixel Bender for mixing two tracks together (per shader passes).

However, would it be technically possible to write a Pixel Bender kernel that could do this?

• Filter LP / HP / BP (with Cutoff and Resonance parameters);
• Delays (with milliseconds timing and feedback parameters);
• Reverb (with Room size, Reverb length, Stereo Width p开发者_StackOverflowarameters);
• Synthesizers (Square, Saw, Sine, Noise, custom waveshapes);

Have a look at Kevin Goldsmith's Pixel Bender Synth too.
