2. Sound generator - Wikipedia

   en.wikipedia.org/wiki/Sound_generator

   A sound generator is a vibrating object which produces a sound. There are two main kinds of sound generators (thus, two main kinds of musical instruments).. A full cycle of a sound wave will be described in each example which consists of initial normal conditions (no fluctuations in atmospheric pressure), an increase of air pressure, a subsequent decrease in air pressure which brings it back ...

3. Programmable sound generator - Wikipedia

   en.wikipedia.org/wiki/Programmable_sound_generator

   A programmable sound generator (PSG) is a sound chip that generates (or synthesizes) audio wave signals built from one or more basic waveforms, and often some kind of noise. PSGs use a relatively simple method of creating sound compared to other methods such as frequency modulation synthesis or pulse-code modulation. [1]

4. Thermoacoustic heat engine - Wikipedia

   en.wikipedia.org/wiki/Thermoacoustic_heat_engine

   Depending on the type of engine a driver or loudspeaker might be used to generate sound waves. In a tube closed at both ends, interference can occur between two waves traveling in opposite directions at certain frequencies. The interference causes resonance and creates a standing wave. The stack consists of small parallel channels.

5. Texas Instruments SN76489 - Wikipedia

   en.wikipedia.org/wiki/Texas_Instruments_SN76489

   The Texas Instruments SN76489 is a programmable sound generator chip from the 1980s, used to create music and sound effects on computers and video game systems. Initially developed by Texas Instruments for its TI-99/4A home computer, it was later updated and widely adopted in systems like the BBC Micro , ColecoVision , IBM PCjr , Sega's Master ...

6. Signal generator - Wikipedia

   en.wikipedia.org/wiki/Signal_generator

   A signal generator is one of a class of electronic devices that generates electrical signals with set properties of amplitude, frequency, and wave shape. These generated signals are used as a stimulus for electronic measurements, typically used in designing, testing, troubleshooting, and repairing electronic or electroacoustic devices, though it often has artistic uses as well.

7. Additive synthesis - Wikipedia

   en.wikipedia.org/wiki/Additive_synthesis

   Additive synthesis is a sound synthesis technique that creates timbre by adding sine waves together. [1] [2]The timbre of musical instruments can be considered in the light of Fourier theory to consist of multiple harmonic or inharmonic partials or overtones.
