KVR Audio

what effect is this when you take an audio signal and invert the waveform every x ms? Is that ring modulation? What is ring modulation? What does this effect I am speaking of sound like and where can I find it? I really need to learn programming I think, because I always have these questions.

All the answers are here my son.

You can modulate your ring til the cows come home with this

Oh so ring modulation is just amplitude modulation (usually with a sine wave)? What Am I talking about then? I think what Im imagining is completely different.

don't know what might do that sort of effect...hmmm....if ya had an lfo to mod the "x ms" that might be very interesting....then again, it might sound like pants!...I dunno

I was just thinking this originally because I have a track that is completely flat on one side and wavy on the other (distortion) so I thought about inverting it every once in a while. As an effect it could be crazy on just about anything I could think of.

EDIT: Im thinking if i ever get into plugin developement Ill make something like bifilter and just make a whole bunch of experimental effects to choose from with 2 or 3 knobs. This being one of them.

Are you talking about a phase inverter? Would inverting the phase every once in a while make it sound any different?

not every once in a while but every once in a few samples would.

I swear there's a plug that does this. I dont remember what it's called. All I remember is that it has a black and white interface.

The track you're talking about...
it sounds to me that it is M/S and not L/R,
where M = L + R and S = L - R,
that could be why one chanel sounds 'flat' and the other is distorted.

Try a M/S utility and see if it can fix your problem.

a ring modulation with a very low sine (or better, square) would do the effect you're talking about

DestroyFX polarizer?

looks like Dozius found our winner

fromDestroy FX website

Polarizer takes every nth sample and polarizes it. The number of samples skipped and the strength of the polarization are adjustable. You can also implode your sound.

while testing this out, I find it important to note that you MAY want to turn your volume down if you DO decide to hit the "implode" parameter. I think I just lost some hearing and I nearly soiled me britches

be careful!

Especially if it's 3:30am and you're supposed to be asleep already.

otherwise- dfx polarizer is not unlike a bit crusher...
nice effect: using nicfit's CCmod to send LFO to the "leap" parameter

As already suggested, ring modulation with a square wave will do this.
If instead of "every x ms" you flip the phase "every cycle" (on the upward zero-crossing) you get an octave divider. This ony works (cleanly) for monophonic sounds. My "Flip Speed" plugin (part of the Psycho Toolkit bundle) does exactly this (among other things...)

Anytime clone ensemble is mentioned that deserves a bump.

I used to use dfx polarizer waaaay too much because I was so intrigued
by what it did.

Oooh. I have dfx polarizer, i just didn't understand it originally. Ill also try the clone ensemble. THanks uys!

What is this effect (invert wave)?
