Introduction to Spectrum Analysis - by David Courtney
ADSR (Attack Decay Sustain Release) envelopes provide a way to specify how sound synthesis parameters such as filter cutoff and gain change over time. They support the synthesis of evolving timbres and are commonly found in analog synthesizers where the envelopes are triggered by pressing keys on the keyboard. With three ADSR envelope generators, AudioMulch's SouthPole contraption provides plenty of scope for envelope controlled filter modulation. In this post I'll demonstrate triggering the envelopes from their built-in pattern sequencers to create rhythmic patterns of filtering and gating.
