(pronounced “an-a-laug”)
    1. A signal that is analogus (or similar) to the original.
    2. Audio that has maintained its form as an electrical alternating current (AC) or simply not digital.
    Example: Audio coming out of a microphone is analog (it is an alternating current). Audio going between an interface and a computer over a firewire connection is not analog, it is digital (1s and 0s).
