The range humans can hear is about 20 - 20,000 Hz (20 Hz to 20 kHz); the range is smaller for older people.
An audio frequency is a frequency, or range of frequencies, of audible sound waves.
Audio output frequency is that range of frequencies that can be heard. For humans, that is generally considered to be the range of 20Hz to 20kHz.
The frequency range used on all modern audio receivers is 10.7 to 12.75 GHz. The IF range is 950 to 2150 MHz. Audio receivers are also known as radios.
Treble.
45-64,000 Hz
treble
There is a bit of an argument on the exact baseband pass frequency for telephone audio, but generally it is in the range of 300 hz to 3000 hz.
An audio signal is a representation of sound, typically as an electrical voltage. Audio signals have frequencies in the audio frequency range of roughly 20 to 20,000 Hz (the limits of human hearing).
http://en.wikipedia.org/wiki/Audio Audio simply means sound, anything you can hear. The average frequency range of human hearing is from 20 Hz to 20 kHz.
RC phase shift oscillator is used to generate frequency in audio range and it is a fixed audio frequency oscillator where as wien bridge oscillator is a variable audio frequency oscillator for high frequency oscillations it is better to design wide band amplifier with LC network

108 to 108 MHz is the radio frequency range assigned to the audio portion of broadcast television channels.
