The documentation of Polynomial Equalizer

Welcome to the full documentation of Polynomial Equalizer.

Polynomial Equalizer is a VST plugin capable of being used in any VST3-supporting DAW.

Feature list

How it works

Polynomial Equalizer works thanks to an FFT processing pipeline.

For each channel:

  • The live audio is deconstructed into frequency data.
  • A frequency-domain transformation defined in the Equalizer is applied to it.
  • The transformed result is then reconstructed and outputted.
