audio frequency
Audible vibration rate
Audio frequency refers to the range of sound waves humans can hear, roughly 20 to 20,000 hertz.
In electronics and acoustics, it distinguishes signals meant to produce audible sound from radio frequencies or ultrasonic waves: The amplifier handles audio frequencies up to 18 kHz.
Often shortened to AF in technical contexts.
