That vid was aimed at the DIY crowd where the next generation of designers is learning the art. I got help from the old goats....now I AM an old goat, so it's my turn.
We are planning to do setup instructional vids for buyers of our finished product at two levels. One or two for the less techy guys who just want to hook up and maybe try the PEQ and another couple for the more adventurous guys with full range systems who want to finely manage their low frequency performance.
DSP is a powerful and fun tool. You can fool around all you want, totally make a mess of things, then "hit reset" and return to the factory settings. For guys who want to learn filter design, I imagine them learning much more quickly than back in the days of capacitors, inductors and resistors. First, you had to have a big library of those parts, then you had to trot back and forth swapping parts, clipping clip leads then swapping CDs in and out of the player. Then you'd forget which combination sounded best, get fatigued and start chasing your tail. It was not easy and sometimes took weeks and weeks. By comparison the new way is a breeze. It can still take a while but at least, now, it's a fun process.
Here's a joke-pic of me, age 45, holding an InfiniCap and failing repeatedly to hit the target on the Blue Heron crossover:
The green tea towels were there because my wife didn't appreciate overheating resistors melting into the carpet.
