Main Sigal Control

All sound come from some pulse or vibrating source. These vibrations can be be modeled, simulated and then replicated with the use of math and computer sound systems. Ghost_Writer can layer and filter signal sources as well as regulate its amount in order to steer and bend that sound to your liking.

Signal Source

Determine the signals: Amplitude, Frequency, Shape, and stereo phase. Phase in Mono, creates an undulating amp effect.

oscil - simple oscillator

The oscil opcode generates periodic control (or audio) signals consisting of the value of kamp (xamp) times the value returned from control rate (audio rate) sampling of a stored function table. The internal phase is simultaneously advanced in accordance with the kcps or xcps input value.

pvsosc - PVS based oscillator

Complex waveforms (ie. all types except cosine) contain all harmonics up to the Nyquist. This makes pvsosc an option for generation of band-limited periodic waves. In addition, types can be changed using a k-rate variable.

ADSR

An ADSR is an envelope of three or more stages, which can be used by another module to shape the amplitude of a signal, acting like a gate, letting sound through and then stopping it again. The stages are Attack, Decay, Sustain, Release.

Resonance Filters

A filter is used to remove (or attenuate) unwanted frequencies in an audio signal. Filters are usually described in terms of their frequency responses, e.g. low pass, high pass, band pass, band reject (or notch) Resonance boost the signals amplification at a certain frequency.

Filter LFO

Low Frequency Oscillator: Used in sound synthesis to modulate a sound attribute such as level at an audibly slow rate. Our LFO is wired to the Filter controls.
