Lots of cool sounding terminology in music making, the meaning of which is usually less cool, but essential to know. This is an A to Z I’ll update as I go along: there are better explanations on the web then I could hope to give so click on the links!
ADSR – Attack, Decay, Sustain, Release.
Amplitude – The maximum extent of a vibration or oscillation, measured from the position of equilibrium. Or as far as we are concerned: volume.
Attack – How quickly a sound reaches maximum level (of amplitude, for example) after the sound is activated. When you press a key, how quickly you hear the sound at the volume level you’ve set.
Band Pass Filter – A device that passes frequencies within a certain range and rejects frequencies outside that range. See also Filter, below.
