unipolar
A unipolar signal is one that is always positive (or always negative),
never crossing through the zero level. In SFX Machine Pro, a sine
wave processed with a DC Offset of 100% would be a unipolar
signal.
value entry field
A box that allows you to enter a numerical value. In SFX Machine
Pro, all values may be entered as floating point numbers, though
the decimal point is not required. Also referred to as a “text edit
field.”
vibrato
A low-frequency variation in a sound’s frequency envelope. In SFX
Machine Pro, you can simulate vibrato by delay modulating a sound
with a sine wave in the 5 to 9 Hz range. (If the carrier is a
sine/triangle/square/saw waveform, you can generate vibrato by
using Frequency Modulation.)
wah-wah
A variable bandpass filter that produces an effect similar to that of a
trumpet mute. It goes “wah.” In SFX Machine Pro, a wah-wah can be
simulated by modulating the cutoff frequency of a bandpass filter
with a moderate Q.
white noise
By analogy with white light (composed of equal amounts of all
visible light frequencies), white noise is a sound composed of an
equal mix of all audible frequencies.
zero-crossing
A point at which a waveform changes sign by crossing the zero-
amplitude axis.
