Definition for Envelope Generator

A synthesizer circuit or software routine that generates a control voltage (or set of digitalDefinition:
A signal or data expressed as series of the digits 0 and 1, typically represented by values of a physical quantity such as voltage or magnetic polarization. dataDefinition:
Information used by a computer in order to arrive at a decision. Although this is a plural term, it's often treated in the singular.) of a predictable nature, most commonly used for controlling the level over time for an amplifierDefinition:
1. A device that increases the voltage or power of a signal. 2. In music performance, a device such as a guitar amplifier that includes speakers and controls to increase the sound level of acoustic or electric instruments., cutoff frequencyDefinition:
The filter frequency where the response is down 3 dB compared to the frequency (or range of frequencies) where response is at maximum. With a lowpass filter, frequencies above the cutoff frequency become progressively more attenuated. With a highpass filter, the same is true for frequencies below the cutoff frequency. for a filterDefinition:
1. (audio) A circuit that reduces certain frequencies, e.g., a low-pass or high-pass filter for audio. Cf. Equalizer. 2. (optics) reduces certain color wavelengths or polarizations., or pitchDefinition:
For a given range of audio frequencies, pitch represents where a single sound falls within that range. for an oscillatorDefinition:
A device that generates a repeating wave or burst, used in test equipment and sound synthesis..
