4.1-- Signal types

There are three types of real-time signal in WaveWarp, as summarized in Table 4.

Table 4 WaveWarp signal types

Signal Type	Description
Mono audio signal	Single channel audio signal, sampled at a given rate, processed in real-time, sample-by-sample using 32-bit floating point precision. Numerical value should nominally be between -1 and +1 to avoid clipping.
Stereo audio signal	Dual channel audio signal, sampled at a given rate, each channel processed in real-time, sample-by-sample using 32-bit floating point precision. Numerical value (of each channel) should nominally be between -1 and +1 to avoid clipping.
Control signal	Single channel floating point number, processed in real-time, sample-by-sample using 32-bit floating point precision. These signals are generally used for modulating parameters of effects, and thus exhibit variations at low frequencies (typically below 100 Hz). They can have any numerical value, but typically fall under two categories: (1) Amplitude controllers (denoted "A" on WaveWarp icons) with a numerical value between 0 and 1, used primarily for modulating the parameters of other components; (2) Frequency controllers (denoted "F" on WaveWarp icons) with a numerical value typically between 0 and SampleRate/2 corresponding to frequency in units of Hz, used primarily for controlling the frequencies of programmable oscillators and filters.
