Anyway, the soundbridge itself is more than powerful enough to do a FIR or IIR in realtime. It’s blackfin shouldnt be at more than 20-30% load while decoding mpeg4 audio. So it would be more suited, but I donno about firmware access politics of roku. seems pretty restrictive. bugger.
You mean hacking it and doing the convolution there? That would be even nicer! What OS does it run?
