Also regarding microcontrollers vs. DSPs: TI has an application note where
they use so-called wave filters (which I know next to nothing about other
than the name and that they can be designed to only require
additions/subtractions and not multiplications in their implementations and
hence execute quickly) for detecting DTMF. I thought it was pretty
clever...
