Crusher
The CrX4’s Crusher is a 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 (BitCrusher) control
enables you to reduce the bit
depth of the output signal
from oo bits (the signal is not
changed) to 1.00 bits.
Reducing the bit depth adds
a harsh, noisy quality to the
sound.
The Cutoff slider is used to set the frequency (in Hz) above which
frequencies are filtered out of the signal. Higher settings produce brighter
sounds while lower settings result in darker sounds. Range 40 Hz...20 kHz.
The Filter Type popup menu right of the Cutoff slider allows you to select
one of four filter types: LP12 (Low Pass 12 dB), HP12 (High Pass 12 dB),
BP12 (Band Pass 12 dB) and BR12 (Band Reject 12 dB).
The Resonance slider 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. Range: 0%...100%.
The Divider slider controls a sample-rate divider that divides the current
sample-rate by the current slider setting. For example, if the current
sample-rate is 44.1 kHz, then setting the Divider slider to 2, halves the
sample-rate to 22.05 kHz. Ranges from 1 to 32.
When the Divider slider (described above) is set to a value other than 1, a
new output sample value must be created for each group of samples in the
input audio stream. For example, if the Divider slider is set to a value of 4,
then four (possibly different) samples in the input stream are replaced by
four samples with a single value in the output audio stream.
