Reference > sinDamped

sinDamped(frequency, timeconstant, phase) Returns a function whose input is a time (in seconds) and whose output is a point on a damped sine wave. You can create a 440 Hz damped sine wave with a time constant of 100 ms using time.map(sinDamped(440, 0.1))

• frequency Frequency of the square wave in Hertz (Hz) or cycles per second.
• timeconstant Time constant of the damped sine wave, in seconds. This is the time it takes to shrink to 37% (i.e. 1/e) of its size. Smaller = faster decay, larger = slower decay.
• phase (optional) Phase shifts the wave to the left or right. A phase of PI shifts the wave a half-cycle to the right. phase can either be a number or it can be a wave, as used in Frequency Modulation.

You can find the code for sinDamped in the synthesine library.
