Electronic Minute No 144 - Ring Modulation w Ingredients.wav

No, I cant really describe what this is! But I use a ring modulator. Two audio signals goes in. I guess the side band frequencies goes out??? Or?! Anyway the original frequencies are also in the mix. SO, two audio signal and the result from a diy ring mod. Have to learn more... Read below!!! In this sound you are listening to, the result, the ring modulation, carrier signal and modulator signal.

After some research...
I write this for myself... Correct me if I'm wrong!!!
From Youtube (AudioCollage)
Ring Modulation is the sum and the differences of the carrier and modulator signal. Feed the ring modulator with 261,626Hz and 391,995Hz and you get (261,626 + 391,995) 653,621Hz and (391,995 - 261,626) 130,369Hz.

From Wikipedia
"...neither the carrier nor the incoming signal is prominent in the outputs, and ideally, not at all."
"...in the basic case where two sine waves of frequencies f1 and f2 (f1 < f2) are multiplied, two new sine waves are created, with one at f1 + f2 and the other at f2 – f1. The two new waves are unlikely to be harmonically related and (in a well-designed ring modulator) the original signals are not present. It is this that gives the ring modulator its unique tones."

Above is true when using pure sine waves! Waves with no harmonics.

I have a passive DIY ring modulator. I guess it's not acting "perfect"...
