Joachim's Tethys filter (9-Feb-05) | Planet Filter Series

## Tethys

A high quality highpass and lowpass filter that uses 48-bit precision butterworth algorithms.
Lowpass freq.
Sound will be gradually attenuated above this frequency. When set to the highest value, the lowpass filter is disabled to preserve CPU.
Lowpass ord.
The steepness (order) of the filter. The steeper the roll-off, the more resonance-like the filter will sound (but there is no resonance involved.) This parameter might not be suitable for automation.
Highpass freq.
Sound will be gradually attenuated below this frequency. When set to the lowest value, the highpass filter is disabled to preserve CPU.
Highpass ord.
The steepness (order) of the filter. The steeper the roll-off, the more resonance-like the filter will sound (but there is no resonance involved.) This parameter might not be suitable for automation.
Inertia
To make the filter more usable in music composing, i've added an inertia parameter, that only affects the lowpass and highpass frequencies. It does not affect the steepness (poles) parameters, because these tend to click when changed.
The steepness (order) of the filter has the following effect on the frequency curve:
