The Siren doesn't come close to having enough cycles to do the job. At 
48kHz complex sampling, the optimized FFT is more than a factor of 6 too 
slow, and that doesn't count the doubling up needed for Forward-Inverse 
pairs for doing fast convolution.

It can easily be set up with IIR filters to do many specific tasks very 
capably, but it's not a general-purpose solution by any means.
