Sample Rate Reduction
▪
Sample rate reduction is a digital signal processing technique
▪
which reduces the rate (frequency) at which samples are stored.
Sample rate reduction affects the signals spectral characteristic
and can be used as an audio effect.
Sideband
▪
Sidebands are spectral components present in an audio signal
above and below the carrier / center frequency.
Spectral Folding
▪
Spectral folding, also known as aliasing, is the result of a sam-
pling frequency too low to correctly sample a given signal. Those
errors are usually audible as “inharmonic”, noise-like frequency
components in the reconstructed signal.
Tilt-EQ
▪
A tilt equalizer is a form of equalizer used for emphasizing one
end of the frequency spectrum of a signal while attenuating the
other.
Trigger
▪
A Trigger is a rectangular control signal with a fast transient
change from its initial state to it’s active state and a fast return
back to its initial state. Unlike the gate signal, the trigger doesn’t
stay on its active state for longer periods of time but immediately
returns to its initial value.
Unity Gain
▪
Unity gain means that the level of audio passing through the
effect is the same before and after the effect. It means an ampli-
fication of exactly 1.0, so if your incoming and outgoing signal
have the same amplitude or loudness, you achieved unity gain.
