Crusher
The Spectral’s Crusher is a Lo-Fi / Distortion effect that combines bit-depth
and sample-rate reduction with “smoothing” algorithms allowing the
resolution of the signal to be decreased, thereby making the sound rougher
and noisier. This effect processor also includes a filter.
The Bits control enables you to reduce the bit-depth (or bit-rate) of the
output signal from oo bits (the signal is not changed) to 1 bit. Reducing the
bit depth adds a harsh, noisy quality to the sound.
The Cutoff dial is used to set the operation frequency (in Hz) above which
frequencies are filtered out of the signal when using a Low-Pass Filter.
Higher settings produce brighter sounds while lower settings result in
darker sounds. You can also use other filter types with the Type Selection
button next to the Resonance dial.
The Resonance dial is used to set the amount of emphasis around the
cutoff frequency. Higher settings create a more pronounced peak in the
signal while lower settings produce a flatter response.
The Type Selection button allows you to choose one of four 12 dB filter
types: LP = Low Pass, HP = High Pass, BP = Band Pass and BR = Band
Reject (also called Notch).
The Auto-Vol button allows a compressor / expander to be switched into the
signal path. This reduces the overall effect of the Crusher making the
sound less harsh and more “musical”.
Hint: When using very low settings for the bitrate, in example just 2 bits, it
can be that a sound below a certain level simply produces no output at 2 bit
