Vinyl Distortion
The Vinyl Distortion
Effect.
The Vinyl Distortion effect emulates some of the typical distortions that occur on vinyl records
during playback. These distortions are caused by the geometric relationships between the
needle and the recorded groove. The effect also features a crackle generator for adding
noisy artifacts.
The Tracing Model section adds even harmonic distortion to the input signal. Adjust the
amount of distortion with the Drive knob, or click and drag vertically in the Tracing Model
X-Y display. To adjust the distortion's frequency or color, drag horizontally in the X-Y
display or double-click on the Freq eld and type in a value. Holding the
Alt
(PC) /
Alt
(Mac) modi er while dragging vertically in the X-Y display changes the frequency
band's Q (bandwidth).
The Pinch Effect section adds odd harmonics to the input signal. These distortions typically
occur 180 degrees out of phase, creating a richer stereo image. The Pinch Effect has the
same controls as the Tracing Model, but generates a rather different sound.
The Drive control increases or decreases the overall distortion amount created by both the
Tracing Model and Pinch.
There are two distortion modes: Soft and Hard. The Soft Mode simulates the sound of a
dub plate, while Hard Mode is more like that of a standard vinyl record.
The stereo/mono switch determines whether the Pinch distortion occurs in stereo or mono.
Set it to stereo for realistic simulation of vinyl distortions.
The Crackle section adds noise to the signal, with noise density set by the Density control.
