dsp.js has an fft implementation, don't know how fast it is.

displaying a scroll-able, zoom-able, eeg time-series might be a job for WebGL.

You can probably just about do the fft in webgl....would be pretty cool!

See http://www.sandia.gov/~kmorel/documents/fftgpu/fftgpu.pdf (which is linked to from http://wildabc.wordpress.com/2012/12/02/webgl-demo-fft-based-droplet-simulation/ - a demo that isn't working for me).
