Bode Shifter: How does it work?
I have Arturia's Moog Modular, and it includes the Bode Shifter. It's the strangest module in the bunch. Just playing with it, I couldn't fully grasp what it was doing. I did a little research, and it seems that it shifts all audio tones not by an equal percent but by an equal number of Hertz, and it appears that when you combine the A and B channels in equal proportion, you essentially have a ring modulator. What I want to know is, how does it work? How does a module raise all tones by an equal number of Hertz? Because I'm thinking it's witchcraft.
Re: Bode Shifter: How does it work?
depending of the settings you can create some ring mod , harmonizer , phazer effetcs
it's possible to shift only certains freq in a sound keep intact some others
please see some examples on my youtube :

A free bode-style shifter in software form so you can play around with it and see what it does:

Now where can I get me an analog bode shifter?

Re: Bode Shifter: How does it work?
But I said at the very beginning that I have Arturia's Moog Modular. i can play around with the Bode shifter to my heart's content. I still have a little difficulty getting a grip on what it technically does. And I want to know how the technology works. What's the math? How does the analog circuitry work? I mean, a ring modulator is kinda easy. It's the same principle as tremolo. You're multiplying one wave by another. But what is the underlying principle with the Bode shifter?

Re: Bode Shifter: How does it work?
Well, I have no idea how it works, but it must have something to do with Bode plots. And since these are a way of representing relationships between frequency and phase, maybe it does some kind of phase shifting on individual frequency components?

It's witchcraft.
