An LFO can be routed to control, for example, the frequency of the audio oscillator, its phase, stereo panning, filter frequency, or amplification.

Hewlett-Packard's first product, built in the garage, was an audio oscillator, the HP200A.

Phase-shift oscillators are often used at audio frequency as audio oscillators.

Hewlett-Packard's first product was an audio oscillator for testing sound equipment that was based on a design developed by Mr. Hewlett when he was in graduate school.

The blue box consisted of a set of audio oscillators, a telephone keypad, an audio amplifier and speaker.

An audio oscillator produces frequencies in the audio range, about 16 Hz to 20 kHz.

These instruments include audio oscillator, attenuator, stroboscope, photometer, colorimeter, algesiometer, algometer, and olfactometer.

Also, there is no audio local oscillator, the injected video carrier serves that purpose.

Candidates are required to copy for five minutes at the speed of five words per minute, international Morse signals from an audio oscillator keyed either manually or automatically.

They decided instead on a variable audio oscillator that was used to test sound quality in the booming radio and movie business.
