Description

Blue Cat's Triple EQ - Semi-Parametric 3 Bands Equalizer DirectX and VST Plugin (Freeware)

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 audio analysis tools for signal-dependant side chain filtering.

For independent left/right channels filtering or stereo widening with mid-side processing, you might be interested in trying Blue Cat's Stereo Triple EQ or Blue Cat's Widening Triple EQ. Check out the Parametr'EQ Series for a complete parametric EQ solution.

  • Warning: because it now supports MIDI events, the DirectX plug-in may appear in the "Synth" or "DXi" category instead of "effects" in some hosts (such as Cakewalk Sonar). If it does not appear in you host, you might want to use our DXi Manager to de-activate MIDI features.
  • Warning: this new version breaks the presets compatibility, and is thus installed as a new plug-in. If you have a previous version installed and do not want to keep it, just uninstall it manually.
