IIEQ ~ Parametric 10-band Equalizer

The IIEQ is a free, fully parametric 10-band equalizer with its own, characteristic sound and low CPU consumption. The 1st and the 10th band are low and high shelf filters, respectively; all other bands are peak filters. Individual bands can be switched on and off (click on the small green buttons!). It is available for Windows (32/64 bit) and Mac (32 bit). Alternative GUIs are available for Windows 32bit only.

SmallEQ ~ Tiny 10 Band Equalization

Sick and tired of huge GUIs taking up all screen space? Want an EQ that easily fits in your pocket but sounds just like the big guys? Then it’s time to meet SmallEQ! The world’s smallest 10-band EQ, sporting eight fully parametric bands plus one low- and one high-shelf filter on exactly 9135 square pixels. Controls from left to right: band choice, gain, frequency, width and overall gain.

ColourEQ ~ Super Parametric Equalization Plugin

Not just another EQ: with its custom-made 4th order IIR filter, ColourEQ sounds unlike any other EQ you have ever come across. It comes with five bands of ”super parametric” peaking filters, which means that there is one more parameter in addition to the traditional gain/width/frequency set that can influence the curve shape. These shapes cannot be reproduced by ordinary IIR equalizers. Further features include: adjustable GUI colours, freely resizable window size, internal 64 bit processing and low CPU usage. Available in Windows VST (32/64 bit), Windows/Mac RTAS and Mac VST/AU format (Intel, OSX 10.5 and higher).

flowEQ ~ New Way To Navigate Equalization

flowEQ uses a disentangled variational autoencoder (β-VAE) in order to provide a new modality for modifying the timbre of recordings via a parametric equalizer. By traversing the learned latent space of the trained decoder network, the user can more quickly search through the configurations of a five band parametric equalizer. This methodology promotes using one’s ears to determine the proper EQ settings over looking at transfer functions or specific frequency controls. Two main modes of operation are provided (Traverse and Semantic), which allow users to sample from the latent space of the 12 trained models.


  • Quick and easy timbral adjustments
  • Automated timbral shifts over time for creative effects
  • Powerful ‘tone controls’ for users in a playback/listening setting
