You can get a nice DSP for that kind of money.

Yeah, although can you get even within even an order of magnitude in group delay (12us w/100kHz cutout) with a $5 DSP? :-)

(While I haven't personally used that IC, other people here have, and I'm told that's why -- they're trying to minimize some big audio system's group delay, making it something like <1ms total.)


That's the crux with DSP, they often can't do that. This is where wave digital filters come in handy but youngsters don't have the foggiest what that is or think it's some tuning device for a surfboard.
