It takes an input signal and outputs the hyperbolic tangent function [tanh(x)] for that signal.\u003c\/h3\u003e \u003cp data-mce-fragment=\"1\"\u003eIn more useful terms, it adds curves to a signal!\u003c\/p\u003e \u003cp data-mce-fragment=\"1\"\u003eTraditionally the circuit is used to shape a triangle wave to a sine but when used with more complex signals it behaves as a single knob limiter.\u003c\/p\u003e \u003cp data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eSpecification\u003c\/strong\u003e\u003c\/p\u003e \u003cp data-mce-fragment=\"1\"\u003eThe tanh has three independent channels for wave shaping.\u003c\/p\u003e \u003cp data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eDescription\u003c\/strong\u003e\u003cbr data-mce-fragment=\"1\"\u003eFor many Max\/MSP and\/or PD users, the [tanh~] object may be familiar. It is likely a much used secret weapon in many contexts!\u003c\/p\u003e \u003cp data-mce-fragment=\"1\"\u003eDescribing what the tanh does to a signal, both mathematically and sonically can be a headache, and not particularly useful. So I will describe some particularly fun use cases to give a bit of context.\u003c\/p\u003e \u003cp data-mce-fragment=\"1\"\u003e \u003cbr data-mce-fragment=\"1\"\u003e\u003c\/p\u003e \u003cp data-mce-fragment=\"1\"\u003eFeedback control:\u003c\/p\u003e \u003cp data-mce-fragment=\"1\"\u003eFeedback is fun. But feedback can get unpredictable.\u003c\/p\u003e \u003cp data-mce-fragment=\"1\"\u003eThe user can insert tanh in the feedback path and use it to reign in runaway feedback. Whether it’s feedback in a delay loop, a reverb, filter or straight up microphonic\u003c\/p\u003e \u003cp data-mce-fragment=\"1\"\u003eIn this context, it functions as a limiter on feedback amplitude.\u003c\/p\u003e \u003cp data-mce-fragment=\"1\"\u003eInstead of fading away to silence, when longer sustain is desired, or running away uncontrollably, a signal can be controlled much more easily with a tanh. There will be a much wider range at which a feedback oscillation will stabilise musically.\u003c\/p\u003e \u003cp data-mce-fragment=\"1\"\u003e \u003cbr data-mce-fragment=\"1\"\u003e\u003c\/p\u003e \u003cp data-mce-fragment=\"1\"\u003eWave shaping:\u003c\/p\u003e \u003cp data-mce-fragment=\"1\"\u003eRunning a triangle wave through a tanh will allow for some interesting wave shape control\u003c\/p\u003e \u003cp data-mce-fragment=\"1\"\u003eFully CCW and the resulting signal will be a slightly attenuated pass through of the original triangle wave. As the level is increased, the corners will soften and the waveform will shape into a sine wave.\u003c\/p\u003e \u003cp data-mce-fragment=\"1\"\u003eWhen a level has increased the sine will soft clip and eventually settle into a unique peaked waveform.\u003c\/p\u003e \u003cp data-mce-fragment=\"1\"\u003e \u003cbr data-mce-fragment=\"1\"\u003e\u003c\/p\u003e \u003cp data-mce-fragment=\"1\"\u003eLimiter\/distortion:\u003c\/p\u003e \u003cp data-mce-fragment=\"1\"\u003etanh reacts very well when the user runs a complex audio signal through one of the channels.
