Perhaps OpenCL is more useful for things like a convolution reverb where
you can offload the processing required to update the impulse whilst the
user edits some parameters. Things like that?
Already done - but using CUDA. See: http://www.liquidsonics.com/software.htm
The point about convolution reverb (as with FFT processes generally) is
that these algorithms are "embarrassingly parallel" - in essence,
large-scale matrix multiplications with 100s or 1000s done
simultaneously. GPU coding should give massive speedups; but we need
those tight deadlines (and high-bandwidth bus transfers) as well.
