Introduction
This page lists some simple function generators that produce waves (suitable for digital audio).
- t Time, a positive number
- d delta, a real number in the range of 0 to 1 (inclusive)
Elementary function generators
Saw
((t/pi) % 2-1)
Additive function generators
Sine to Saw (additive)
Bend a SINE wave into a SAW wave.
t = time (positive) d = Proportion of each wave (0-1, where 0 is all SAW and 1 is all SINE).
(1-d)*((t/pi) % 2-1) + (d)*(sin(t))
