power
SFX Machine Pro’s Raise to Power process distorts the shape of a
signal by raising it to a power (exponentiating it, or multiplying it by
itself a fractional number of times). This results in a distorted sound
with additional harmonic content.
Preset
An effect in SFX Machine Pro.
Preset Editor
The screen that gives you direct access to all of the pop-up menus
and parameters that define a patch.
process
In SFX Machine Pro, a process is a DSP algorithm that either
modifies a sound (e.g., delay, lowpass) or extracts information from
it (Envelope Follower, Pitch Tracker). The output of the process is
sent to the modulation block as well as to the left and right outputs,
if selected.
Do not confuse a DSP process with the Process button, which tells
SFX Machine Pro to process the audio and send it back to the host
program.
Q
A parameter that controls a filter’s roll-off slope and the (inverse)
width of its resonant peak.
For a bandpass filter, the Q is the ratio of the filter’s center
frequency to its bandwidth. For example, if the filter’s cutoff
frequency is 500 Hz and its bandwidth is 50 Hz, its Q is 10.
In SFX Machine Pro, a Q of 1 results in a roll-off of 12 dB/octave for
the lowpass and highpass filters, and 6 dB/octave on either side for
the bandpass filter. Higher Q values result in higher slopes and
place a sharp resonant peak at the cutoff frequency.
quantization
The process of limiting a value to one of a discrete number of
values; for example, representing an audio sample as a 16-bit
integer. Sampling also involves quantizing time, by sampling at
discrete intervals.
