Effect Block
19 Lo-Fi Processor
BitRate (Bit/Rate down)
1.
Pre Filter (Pre-Process Filter)
Value: Off, On
This is the switch of the filter placed before the Lo-Fi
processing. When set “ON,” this suppresses the
digital distortion by lowering sample rates.
2.
Sample Rate
Value: Thru, 1/2–1/32
Sets the fraction of current sample rates to be used for
processing. You set the Sample Rate parameter to
“Thru” if no change is desired.
3.
Down to...
Value: 16–1 bit
This setting is for reducing the bit count. When this is
set to 16 bit, the bit count currently used is preserved.
4.
Post Filter (Post-Process Filter)
Value: Off, On
This is the switch of the filter placed after the Lo-Fi
processing. Like the pre-process filter. When set
“ON,” this suppresses the digital distortion by
lowering sample rates.
5.
Effect Level
Value: 0–100
Sets the volume of the effect sound. It is ordinarily set
to 100.
6.
Direct Level
Value: 0–100
Sets the volume of the source sound. It is ordinarily
set to 0. Raise this when you want to mix the source
sound.
Both the pre-process and post-process filters are
necessary components in general digital sound
processing. These allow the suppression of digital
distortion that occurs when the sample rate is
lowered, or to allow distortion when turned off.
