Audio functions

Introduction

This page lists some simple function generators that produce waves (suitable for digital audio). Each element is typically a float (or double) in the range -1 to 1.

• 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. A delta (d) dictates how much SINE and SAW wave to add together.

(1-d)*((t/pi) % 2-1) + (d)*(sin(t))
