LP10 is a mixdown/mastering EQ. It comes with 10 bands and a huge number of filter types per band: peak, notch, low and high pass with 12 and 24 dB per octave, two band pass filters, a low and a high shelf filter, plus a whole set of Butterworth filters up to 10th order. The frequency response is exactly matched to analog RLC circuits. As a novum, the LP10 is a variable phase EQ: the phase response can be freely tuned, from minimum phase over linear phase to inverse minimum phase. Furthermore, the Butterworth filters' order/steepness can be varied to include non-integer values. A frequency analyzer is included. The GUI is freely resizable.
