Audio is sound within the acoustic range available
to humans. An audio frequency (AF) is an
electrical alternating current within the 20 to
20,000 hertz (cycles per second) range that can
be used to produce acoustic sound. In
computers, audio is the sound system that
comes with or can be added to a computer. An
audio card contains a special built-in processor
and memory for processing audio files and
sending them to speakers in the computer.
