If your goal is to get an application running cheaply rather than the
(admittedly fun) process of building and/or programming DSP audio
systems, why not just use the host CPU? With dual Athlons and low
latency patches, you have a huge number of CPU cycles per sample
available at the drop of a millisecond. Not to mention a nice,
standard development tool chain. I expect a 1 GHz Athlon ($70) is the
equivalent of several state-of-the-art DSPs, and cheaper as well.
My hifi "preamp" is a PC with Athlon 900 Mhz processer and RME
Hammerfall. It is loafing along at 35% utilisation while doing 24,000
tap convolutions on 6 channels at 48 kHz (with fft-based convolution
algorithm).
