Not just another EQ: with its custom-made 4th order IIR filter, ColourEQ sounds unlike any other EQ you have ever come across. It comes with five bands of \”super parametric\” peaking filters, which means that there is one more parameter in addition to the traditional gain/width/frequency set that can influence the curve shape. These shapes cannot be reproduced by ordinary IIR equalizers. Further features include: adjustable GUI colours, freely resizable window size, internal 64 bit processing and low CPU usage. Available in Windows VST (32/64 bit), Windows/Mac RTAS and Mac VST/AU format (Intel, OSX 10.5 and higher).
