ADSR Envelope and Gate Signals

  This article will discuss the basics of both envelopes and gate signals. Both the concepts are closely related and putting them together will be more meaningful.   What is an envelope signal?   An envelope signal is a subsonic, aperiodic, unipolar positive and...

Voltage Controlled Amplifier (VCA) Explained

  What is a VCA?   A VCA is a processor that can alter the amplitude of a signal proportional to the control voltage applied to its amplitude modulation control input. In simple words it is just an amplifier whose output you can control with a control signal....

FET Compressor

Field Effect Transistor   FET compressors, which stands for field effect transistor, are devices from the family of dynamic audio effects. So how did they come about? As small transistors began to replace large tubes, later compressor devices were based on field...

Sample-Based Synthesis

Synthesize Using Samplers   Sample-based synthesis is a form of audio synthesis that mainly involves use of samplers, either hardware or software. The main difference between this form of audio synthesis and the others is that it uses sampled sounds or...

Phase Distortion Synthesis

What is PD synthesis?   Phase distortion synthesis (also known as PD) is a form of synthesis originally developed by Casio company. They presented it for the first time in their CZ series of synthesizers. In the 1980`s Casio`s engineer Mark Fukuda invented this...
