Automation

A tool that allows you to change the variable parameters of a sound over time. By plotting points of automation it is possible to make Manipulations (effects) change over time. This allows the compose...

Art of Noises

Written by Luigi Russolo, the leaflet argued that traditional orchestras limited themselves to only four or five different types of sounds: Instruments played with the bow, Plucked instruments, Brass ...

Analogue

A continuious signal in time, which in music, allows for the continuious capture of audio signals. Prior to digital technology all systems were analogue. Though analogue systems allow for a faithful, ...

Amplitude Modulation

A type of manipulation in which one input signal modulates the amplitude of another sound. When done in the sub-audio range by, for example a LFO (Low Frequency Oscillator) sine wave, the result is a ...

Amplitude

A technical term that describes loudness. The higher the amplitude of a sound wave, the louder it is. The amplitude relates to the amount of displacement that the sound wave vibration exerts. Take car...

Amplification

The boosting of a signal’s amplitude so as to increase the perceived volume and energy of the sound signal. Amplifiers may be electronic, or might be acoustic resonators (such as a guitar’s sound box)...

Algorithmic music

Algorithmic music involves the application of algorithms as part of the composition process (an algorithm is a procedure or formula, e.g., for solving a problem). This term is one of the most employed...

ADSR

ADSR (Attack, Decay, Sustain, Release) is a term used to describe the shape of sounds over time (see also envelope). Sounds that begin very quickly (for example a click) can be described as having a f...

Additive Synthesis

A process of creating sounds in which complex sounds are made from the combination of simpler elements (such as sine waves). Different types of simple sounds can be combined to create ever more comple...
