The maximum deviation from the average or equilibrium value of any repeatedly changing quantity, such as the position of a vibrating object, pressure, velocity, voltage, current and many others. The amplitude of a sound wave is the maximum amount by which the instantaneous sound pressure differs from the ambient pressure. The variation of (maximum) amplitude over time is called the envelope of the sound. (Source: Barry Truax - Handbook for Acoustic Ecology CD-ROM Edition.
