The Analogue systems RS-85 module is a voltage controlled LFO with four wave form outputs, reset and a very wide frequency range, up to audio frequencies so you can use the module as an auxilliary oscillator.
Not all periodic oscillations lie within the range of audible frequencies,but this does not mean that you cannot hear them. For example, a violinist’s vibrato may take the form of an oscillation at,say,5Hz,while the growl produced by over-blowing a brass instrument may occur at 18Hz. Even in isolation, you may hear a periodic waveform at subsonic frequencies - for example, a clock oscillator with an output of 1Hz will sound like a series of repeating clicks. (Strictly speaking, these have a high bandwidth due to the transient nature of the waveform, and you would not hear a sine wave at the same frequency, but that is not the point.)
Synthesisers have a class of oscillators- Low Frequency Oscillators (LFOs) - that create these, and many other, effects.They can add vibrato to a sound, produce growl, act as low frequency clocks and, on some synthesisers, double as audio frequency oscillators.
