I'm working on an effect that splits a signal into frequency bands and applies a delay to each band. However, there is a lot of clutter in the high-end (there's 16 delays working together). How could I best remove some of this in the patch?

I've tried low-pass filters on each of the outputs (tuned to the band's frequency range), but it's still pretty wild. Is there anything close to a brickwall filter in PD?

Thanks in advance.

How are you scaling your bands? If your just doing a linear scaling, that could be the source of your troubles.

You probably want bands a bit lime this:

(In hertz)

100, 200, 350, 550, 800, 1100, 1500, 2000, 3000, 4500, 6000, 9000, 12000, 17000

Ok, so i just did that in my head, and it's only 14 bands, but that should be the basic shape.

Bands are

100 200 250 400 650 800 1100 1200 1300 1500 1700 2000 2200 2500 2800 3000.

I've been meaning to re-organise them, the values I have now are taken from a vocoder patch. Is there any math behind scaling bands that I can apply?

I'll try your bands tomorrow. It's 3am and I just got in from work.

Edit -----

Tried your band values. Seems a lot less cluttered, more spaced. Going to try a few combinations, but yours is a good starting point. Thanks!
