mmm-
I can agree to that.
It's obvious that DSP effects work and they do not all sound the same.
The different effects have different waveforms when rendered to prove it.

however-
multiplication and division sound the same, I think any rounding errors are inconsequential when using a normal bitrate.

-- they are essentially exactly the same.
If you took a 440 hz sine with .5 peak, and multiplied it by .5 and rendered that
and the same sine and divided it by 2
they would null when phase inverted for sure, without any noise or inconsistencies at all
This test could be extrapolated by multiplying them again by 2 and dividing it by .5 unto say 1000 iters
to see if they would still null perfect
--they prolly would

Ok, lol; so I feel having no de-zip can be very relevant. But obviously using it while configuring or affecting settings there is a great strength to its being utilized.

To that end I've made a usable example which can be found in the beta of the shelf EQ which is available here:

(just look within the code which contains the coefs for the hp and lp).

I'm designing a virtual effects pedal that requires different knobs to have certain frequencies can I do that with the dezipper?
Whomever helps me figure this out will be given a big thank you

the de-zipper merely adds a bit of tension and latency feedback. It's a subtle sound and I suppose you could use a few of them in tandem to create a bit of fuzziness, sort of like the wave brand fx. They have their own color and I guess it's something similar but, obviously different.
