Viator DSP Releases FREE Multi-Q: Three EQ Models in One Plugin

Viator DSP has released Multi-Q free effect plugin with three EQ models: a graphic, parametric, and tube EQ.

You can use all three EQs at once if you wish or just one band. The filters turn off at 0 dB of gain to save precious CPU, so don’t be afraid to load it up to just use one band. Multi-Q also has low and high pass filters, a drive for tube distortion, mid/side processing, oversampling, and phase inversion. Use the 3 buttons on the right side to switch EQ UI focus and have at it!

Although the UI looks like famous analog EQs, this isn’t supposed to be a hardware emulation, just a familiar interface and a starting point for creativity.


  • Graphic EQ: 10 EQ bands from 31 to 15K hertz each with -12 to 12 dB of gain. These bands also use proportional bandwidth to behave more like hardware.
  • Parametric EQ: 4 EQ bands, each with its own frequency selecting knob and -12 to 12 dB of gain.
  • Tube EQ: 2 sets of EQ bands each with a boost and cut knob for highs and lows. There’s also a frequency selecting knob for each set of bands and a shard bandwidth knob.
  • High and Low pass filters.
  • Drive for tube-style saturation.
  • Output trim to control the output volume.
  • Reset button to reset all sliders for the chosen model to 0 dB.
  • Quality menu to select between no oversampling and 2 times oversampling.
  • Stereo menu to select mid/side processing choices – which are stereo, mids, or sides.
  • Phase invert button.
  • CPU monitor that can be toggled on or off.
  • Ability to type values into the dials and faders.
  • Filters individually turn off when set to 0 dB to save on the CPU, same goes for the drive and the high/low pass filter when set to 20 and 20K hertz respectively.

Multi-Q is available to PC and Mac users in 64-bit VST3 and AU plugin formats. Although is free, donations to the author are appreciated.
