The part of the sound signal that affects the loudness. Used to boost the volume of the signal.
Analog
Refers to any piece of equipment that uses older components to generate sounds.
<
Attack
The start of a sound. The first stage in an ADSR envelope.
Channel
One Seperate sound output.
Compression
An effect that boosts the low frequencies of the sound to give the bass more "punch".
Cutoff
The phase of frequency cancellation when cutting out frequencies with a filter.
Decay
The stage of sound between the attack and the sustain in an envelope.
Delay
An effect that repeats and copies the sound signal multiple times with gradually decreasing volume.
Envelope
The shape of a sound, determined by various timing changes after a keypress or trigger.
G-S
Gate
The phase of frequency cancellation when cutting out frequencies with a filter.
Harmonics
Individual frequencies in a sound.
HPF
High Pass Filter. Allows only high frequencies.
Input
Channel in a synth for running another sound source into its signal.
LFO
Low Frequency Oscillator. Creates a "vibrato" or "tremolo" effect.
MIDI
Musical Instrument Digital Interface. Method of running different electronic gear in sync with one another.
Octave
One range on a keyboard from lower note to middle note, middle note to high note. (e.g.: All of the keys in between lower C and middle C.)
Oscillator
Sound generation source.
PCM
Pulse Code Modulation. A method of sound synthesis using recorded samples of instruments as the sound source, and digitally altering the pitch across the keyboard.
Pitch
The frequency measured by keyboard note.
Polyphony
The maximum number of notes that can play simultaneuosly on a keyboard.
PWM
Pulse Width Modulation. A type of oscillator.
Release
The fourth and last stage on an ADSR envelope. The tail of the sound where it either stops abruptly or fades out.
Sustain
The third stage of an ADSR envelope in between the decay and the release.
