E-MU Digital Audio System 51
Distortion
Most audio processors aim to provide low distortion, but not this one! The sole purpose
of this effect is to add distortion, and lots of it. This effect provides “fuzz box” style,
clipping distortion which is particularly effective on guitar, bass, organs, electric pianos
or whatever.
The input signal first passes through a lowpass filter. The Lowpass Filter Cutoff
Frequency allows you to control the number of new harmonics that will be generated by
the distortion element. The distortion element has an Edge control which controls “how
much” distortion will be added. A bandpass filter follows the distortion generator. The
EQ Center control lets you select a particular band of frequencies to be output. The EQ
Bandwidth controls the width of the center frequency band. Finally, a gain control
allows you to make up for any gain loss through the effect.
Use the Wet/Dry mix control in conjunction with the Edge control to reduce the
amount of distortion, or go wild and turn everything to 11!
Attack Time Controls how quickly the gain is turned down after the signal
exceeds the threshold. Range .1ms to 500ms
Release Time Controls how fast the gain is returned to its normal setting after
the signal has fallen below the threshold.
Range: 50ms to 3000ms
Pre-Delay Allows the use of slower attack times without missing signal peaks.
Range: 0ms to 3 ms
Input Meter Allows you to monitor the strength of the input signal.
Gain Reduction Meter Shows the amount of gain reduction being applied.
