A technology for recording or transmitting sound (or audio) as a continuously-varying analog signal. The predecssor of digital audio. Most digital audio equipment still incorporates some analog audio technology.

By contrast with digital audio,
implies audio which has not been
irreparably savaged by conversion
from the analog domain to numbers and
back again. Analog audio technologies,
while often lacking the convenience of some digital ones, have&a better
chance of retaining the heart and soul
of music. See vinyl.
