Wet filter question

[Alexander]

Hello,

I am reading in the nord modular book by James J Clark about wet filters. Chapter 3.5 (page 43) gives a small explanation on dispersion as a method to obtain "wetness".
It reads "different frequencies having different delays", but in the example patch on the next page, (see attachment), the delays are all controlled by a single constant.

Doesn't this demonstrate different frequencies with equal delay times?

(other theory and examples on (wet) filter design are very welcome!)

Thank you.

I completely overlooked that. Thanks.

I am actually working with the msp filters and trying out all sort of things. Wet filters is just a strange term, but it describes the character of one. Patch noise into both the carrier and modulator of an vocoder and you'll have an example of "wetness".
As described in the book, the filters in the nord will sound "moister" never really "wet"!

Wonderful things, though, filters!

The wetness is indeed the result of the frequency-dependent phase-dispersion, that and a bit of resonance. This is one thing that analog filters seem to have all over their digital counterparts, although I was pleasantly surprised by those on the NM.

You can get phasers (all-pass filters) to sound wet too, if you use an envelope follower to modulate the phaser's frequency, you can get pretty far.
