A simple unit generator called OSC could generate a sinusoidal waveform of a specific frequency (given as an input or argument to the function or class that represents the unit generator). ENV could be a unit generator that delineates a breakpoint function. Thus ENV could be used to drive the amplitude envelope of the oscillator OSC through the ...
A pure tone's pressure waveform versus time looks like this; its frequency determines the x axis scale; its amplitude determines the y axis scale; and its phase determines the x origin. In psychoacoustics , a pure tone is a sound with a sinusoidal waveform ; that is, a sine wave of constant frequency , phase-shift , and amplitude . [ 1 ]
Simplified diagram of how a tonewheel works Goldschmidt tone wheel (1910), used as an early beat frequency oscillator. A tonewheel or tone wheel is a simple electromechanical apparatus used for generating electric musical notes in electromechanical organ instruments such as the Hammond organ and in telephony to generate audible signals such as ringing tone.
Korg Triton rack-mountable sound module. A sound module is an electronic musical instrument without a human-playable interface such as a piano-style musical keyboard.Sound modules have to be operated using an externally connected device, which is often a MIDI controller, of which the most common type is the musical keyboard.
An effects unit is also called an effect box, effects device, effects processor or simply an effect. The abbreviation F/X or FX is sometimes used. A pedal-style unit may be called a stomp box, stompbox, effects pedal or pedal. Unprocessed audio coming into an effects unit is referred to as dry, while the processed audio output is referred to as ...
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 ...
The notes used in music can be more complex than musical tones, as they may include aperiodic aspects, such as attack transients, vibrato, and envelope modulation. A simple tone, or pure tone, has a sinusoidal waveform. A complex tone is a combination of two or more pure tones that have a periodic pattern of repetition, unless specified otherwise.
If the generators are all the prime numbers up to a given prime p, we have what is called p-limit just intonation.Sometimes some irrational number close to one of these primes is substituted (an example of tempering) to favour other primes, as in twelve tone equal temperament where 3 is tempered to 2 19 ⁄ 12 to favour 2, or in quarter-comma meantone where 3 is tempered to 2 4 √ 5 to favor ...
