Blue Cat's Triple EQ is a 3 bands semi-parametric equalizer that can be controlled as a single filter with customizable shape.
It includes 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 graph shows the computed frequency response of the plug-in, so that you can exactly know how your signal is processed. The controls are now directly available on the filter graph, making the design of the filter shape even easier.
The Smooth Update mechanism has been included in this plug-in so that you can control the EQ in real time with automation curve or MIDI: you will get an absolutely zipper-free clean and continuous time-varying equalization with absolutely no latency. It makes this plugin the ideal companion of our for signal-dependant side chain filtering.
Cut-Only Equalizer. Term used to describe graphic equalizers designed only for attenuation. (Also referred to as notch equalizers, or band-reject equalizers). Usually applied to active designs. The flat (0 dB) position locates all sliders at the top of the front panel. Comprised only of notch filters (normally spaced at 1/3-octave intervals), all controls start at 0 dB and reduce the signal on a band-by-band basis. Used only in permanent sound systems. Proponents of cut-only philosophy argue that boosting runs the risk of reducing system headroom.
