Granular Synthesis

Granular synthesis is a type of audio synthesis that breaks a sound into small particles. After that, this process reorganizes the particles in order to create a new sound. In short, it is a sound manipulation technique that involves sound grouping, pitch control, and speed control.  A Little Bit of History: Granular Synthesis Around 1946,…

Additive Synthesis

Additive synthesis is one of the oldest and most researched types of audio synthesis. This technique was first used with church organs to accurately control the register-stops, as well as with the keyboard. The operation was quite simple. By pressing the keyboard’s keys and pulling several register-stops in different positions, the air released into the…

Physical Modeling Synthesis

Physical modeling synthesis refers to sound synthesis methods in which a mathematical model calculates the waveform of the sound to be produced. This approach also uses a set of equations and algorithms to mimic the physical source of a sound. It uses partial differential equations, as well as the laws of acoustics, to describe the physical structure of a musical instrument. In…

Linear Arithmetic Synthesis

Linear Arithmetic Synthesis, or LA synthesis, is a type of audio synthesis. In particular, this one is backed up by the theory that the attack transient of a sound is essential for human perception. It uses a combination of simple digital oscillators and sampled attack transients. The oscillators involve pulse and saw-tooth waveforms to produce…

Phase Distortion Synthesis

To understand phase distortion synthesis, we must first go back to its basics. Casio company created phase distortion, or PD. This company engineers launched the original idea for the CZ series of synthesizers, which involved a Cosmo Synth System. Isao Tomita later perfected the Cosmo Synth System. He was a Japanese synthesis-composer and one of…

Sample-Based Synthesis

Sample-based synthesis is a type of audio synthesis that uses either hardware or software samplers. The process involves the use of instruments or sampled sounds as the basis for its sounds.  Sample-Bases Synthesis: the History Before digital sampling became popular, machines used analog tape decks to playback sampled sounds. Machines evolved and more powerful samplers appeared.…

Voltage Controlled Amplifier Explained

This entry aims to explain how a voltage controlled amplifier works. It is a device that can modify the amplitude of a signal. This device involves two types of inputs: the carrier and the modulator. The carrier, also known as the signal input, is where the bipolar input comes in. The modulator, also known as…

Envelopes: the Basics

This entry explains the principles of envelopes. To begin with, an envelope signal is a subsonic, aperiodic, unipolar, and timed signal used to modify the volume curve of an audio signal. To better understand envelopes, you should also know what a gate signal is. The gate signal is a two-state signal that is capable of…
