Overview
Overview
Decimort is a stereo high quality (ultra low aliasing) bit crusher.
After loading the plug-in within a host application, the GUI will appear:
There are two sections:
• Congurationandpresetmanagement
• Signalprocessingcontrolsectionconsistsoftheallremainingcontrols.

of this effect unit and its control parameters.
Basic modules
The inside of Decimort consist of a few basic components, that correspond to the sections on the graphical interface:
Dual decimation unit
It is able to process two channels separately (left and right of stereo channel) in stereo mode, or only single channel
(left) in mono mode.
Decimator is controlled by two parameters:
• Bits – Number of bits the input signal is downgraded to. Values we can choose from
range 1 to 16 bits and additional value: Off, which means the input signal won’t be
downgraded in amplitude domain.
• Frequency – New sampling frequency to which the is degraded to in time domain.
There’s yet another control on a GUI, namely AA LFP – Anti Alias Low Pass Filter. Turn
thisbuttonontosetadditionallowpassltersynchronizedwithFrequency, to protect
the signal against a “resampling images”.

Singleltersectioniscontrolledbyafollowingparameters:
• Filter type–There’re4typesoflterswecanchoosefrom:LP (low pass),
BP (band pass), HP (high pass) and BR(bandreject).OFF position – turns

• Cutoff–CutofffrequencyforLP and HP, and center of the band for BR and BP.
• Reso/B.Width – Resonance for LP and HP, and band width for BR and BP.
• Order – This switch has two values: when switch set to Pre,signalisltered
then decimated, Post–inthisposition,signalisrstdecimatedandthen
