Tanh[3] is a nifty little module from Instruō.
The Instruō tanh[3] is a three channel waveshaper, limiter, overdrive, and feedback controller. Each channel of the tanh[3] takes a signal input and outputs the hyperbolic tangent function (tanh (x)) for that input signal.
What? They say, “Understanding what the tanh[3] does to a signal, both mathematically and sonically can be hard to explain, but it essentially adds curves to signals.”
I got tanh[3] for use in delay feedback loops, where it acts as an expander/limiter to keep the feedback under control. It also turns out to be great for adding distortion to a sine or triangle wave oscillator.
To understand it, I had to look at it on a ‘scope. I made a video to help explain it.
