Detailed Description

Discrete Summation Formula Synth

Ruby version: Synths::Dsf

This produces a wave corresponding to the equation

inf  n-1
 Σ  b    * sin(n*wt)
n=1

Where b is "brightness", valued from 0 (a sine wave, sine.h) to 1 (a cotangent/2 wave, containing equal amounts of all frequencies, cot.h).

If the scale parameter is set, the amplitude of the wave will be decreased such that the peak is always under 1.0.
