Tilt EQ is a free VST plugin to
achieve a linear tilt function with a single knob.
This way the spectral balance of audio material can
be changed very easily without introducing
The center frequency of the tilt
function is 1300 Hz.
Tilt EQ is based on FIR filters that
can be either linear or minimum phase. Baxandall
minimum phase IIR filters also have been implemented
in order to allow further adjustments. The following
graphs show second order Baxandall shelving filters
in comparison to the FIR approach with linear slope.
The tilt of the slope can be set by the linear tilt
knob. The steepness of the slope is given in dB/oct.
Available for Windows.
