The phrase "audio frequencies" is correct and usable in written English.
It can be used in contexts related to sound, music, audio engineering, or any discussion involving sound waves within the audible range for humans.
Example: "The audio frequencies produced by the speaker were clear and well-defined, enhancing the listening experience."
Alternatives: "sound frequencies" or "audible frequencies".
I use two transmitters on this tour tuned to specific audio frequencies.
The smaller the loudspeaker the lower the power it can accept and the less the output of low audio frequencies.
Young people can hear audio frequencies ranging from about 30 hertz to 18 kilohertz, but, as they grow older, hearing ranges from about 100 hertz to 10 kilohertz.
What do all those 60 Hz and 18 Khz labels mean? A. Many digital audio jukebox programs, like MusicMatch Jukebox, WinAmp and iTunes, include an equalizer component that enables you to adjust specific audio frequencies to enhance the overall sound of a certain style of music.
Nonlinearities in the cochlea can introduce audio frequencies that are not present in the sound signal entering the ear.
In this paper an experimental study is presented on active control of a clamped plate at audio frequencies by using feedback controller and electromagnetic actuator.
Then the device creates an inverse audio frequency, which is intended to sonically "cancel" out the original noise.
But the members found a way to play together without creating clutter: by manipulating the audio frequency, they isolated different elements of each record so that one D.J. might supply the bass line while another supplied a kick drum.
The device works day or night by shining an intense beam of light (often produced by an infrared or ultraviolet transmitter or a laser), modulated at an audio frequency, at overhead clouds.
The frequency response of the microphone is very flat in the audio frequency range.
The electrical circuit used was a modified simplified simulation of audio frequency track circuit.
