random
A random sample is one whose value does not appear to depend on
the previous sample’s value, or on anything else. A series of random
samples sounds like white noise.
resonance
A spectral peak in the response of a filter, the body of a musical
instrument, etc. If an external disturbance (for example, an
earthquake) happens to match the resonant frequency of an object
(for example, a house), the resulting vibration can be greatly
amplified.
SFX Machine Pro uses resonant filters, which have a peak near the
cutoff frequency. Increasing the Q makes the peak higher and
narrower.
Ring Modulation
A form of modulation in which two bipolar signals are multiplied
together. The modulator and carrier frequencies disappear and are
replaced by tones at the sum and difference of their frequencies.
If the modulator’s frequency is below 20 Hz, the result is a tremolo
effect. If the modulator’s frequency is itself in the audible range, the
result is a curious change in timbre. As the modulator frequency
increases from 0 Hz, you can hear the resulting signal splitting into
two frequency components, which gradually move away from each
other.
sample
A number representing the amplitude of a signal at a given instant
in time.
sample-and-hold
A sample-and-hold samples a signal at a specified time interval. It
holds the output at that level until the end of the hold time and then
grabs another sample. This process is also called “downsampling.”
sample rate
Sample rate describes how frequently an analog audio signal is
sampled as it is converted into a series of numbers.
44.1 kHz is the standard sample rate for compact disks; 48 kHz is
