Triple EQ is a free 3 bands semi-parametric eq by Blue Cat that can be controlled like a single filter, with customizable shape.
It features a low shelf filter, a high shelf filter and a boost/cut peak filter. Its wide range of gain (+/-40 dB per band) and bandwidth (.01 to 5 Octave) makes it very versatile to create any filter shape.
The three filters are linked together so that when you change the center frequency or the bandwidth, the parameters of the three filters are modified accordingly: you can control the entire equalizer characteristics with a single mouse click.
The good thing about this plugin is not the fact that it is only free but it also offers a dual channels version, with independent left/right or mid/side equalization capabilities. Both channels can be linked together in many ways, letting you transform this plugin into a frequency-dependent panner and much more.
