TDR Nova ~ Cross-platform Equalizer Plugin


NOVA is a parallel dynamic equalizer. Appearing in the familiar layout of a parametric equalizer, each band also includes a full featured dynamics section allowing the processor to cover an impressively wide range of applications. Be it a master lacking density, the drum bus asking for more crispiness, or a sibilance problem in your perfect take: NOVA has an elegant answer.

A user friendly WYSIWYG drag and drop display paired with a classic “knob” interface gives quick and smooth access to the various parameters driving NOVA’s powerful processing capabilities. With its four dynamic EQ bands and additional high-pass and low-pass filter sections, NOVA can meet the most exotic demand. Intuitive equal loudness functions help finding the optimal setting without getting distracted by loudness differences.

In practice, the processor covers a whole bucket of tasks:

  • Parametric equalization
  • Dynamic equalization
  • Frequency selective compression
  • Multi-band compression
  • Wideband compression

Of course NOVA features all helpers and workflow enhancements you’ve come to expect in a TDR plugin: A preset manager, undo/redo, A/B, detailed documentation, copy & paste, and much more.

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).

NorQualizer ~ Automatic Normalizer & EQ


NorQualizer is a smart audio equalizer/normalizer which corrects audio files to get them all similar in terms of bandwidth and volume level. Especially useful for preparing audio CDs with files from different sources.

Features:
  • Extract audio from multimedia files
  • Automatically normalize audio
  • Automatically equalize audio
  • Ideal for creating music albums

Wok Loudness ~ Dynamic Equalization


Wok Loudness simulates the loudness button on old HiFi amps, which alters the frequency response curve to correspond roughly with the equal loudness characteristic of the ear at lower volumes.

The level of high and low frequencies is increased at low listening levels, to compensate for the fact that as the volume of audio decreases, the ears lower sensitivity to extreme high and low frequencies may cause these signals to fall below threshold.  As a result audio material may seem to become ‘thin’ sounding at low volumes, losing bass and treble, the ‘Loudness compensation’ button (often just labelled ‘Loudness’ or ‘Loud’) is intended to rectify this situation.

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.

Applications:

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

EasyQ ~ Easy-To-Use Equalizer


EasyQ is an easy-to-use equalizer with an arbitrary number of filter stages in series connection. Each of the filter stages can operate in one of the following modes: peak/cut (aka bell or parametric EQ), high- or low-shelving, notch and low- or highpass (both with either 6 or 12 dB/oct slope). EasyQ is also easy on the CPU and just does what an EQ is supposed to do without performing any additional voodoo. As such, it is well suited to serve as a go-to EQ for the routine equalizing tasks.

Key Features:

  • unlimited number of filter stages (“bands”)
  • each stage can be one of the following characteristics: bell, low-/high-shelf, low-/highpass (6 or 12 dB/oct), notch
  • clean equalization – no additional colorations
  • low CPU usage
  • +-48 dB gain range
  • stereo modes: linked, left/right, mid/side and mono
  • minimum phase response
