released: SlickEQ

TDR SlickEQ main flat

TDR VOS SlickEQ is a mixing/mastering equalizer designed for ease of use, musical flexibility and impeccable sound.

Three (and a half) filter-bands arranged in a classic Low/Mid/High semi parametric layout offer fast and intuitive access to four distinct EQ modes, each representing a set of distinct EQ curves and behaviors. An elaborate auto gain option automatically compensates for changes of perceived loudness during EQ operation. Optionally, SlickEQ allows to exclusively process either the stereo sum or stereo difference (i.e. “stereo width”) without additional sum/difference encoding.

In order to warm up the material with additional harmonic content, SlickEQ offers a switchable EQ non-linearity and an output stage with 3 different saturation models. These options are meant to offer subtle and interesting textures, rather than obvious distortion. The effect is made to add the typical “mojo” often associated with classy audio gear.
An advanced 64bit multirate processing scheme practically eliminates typical problems of digital EQ implementations such as frequency-warping, quantization distortion and aliasing.

Beside the primary controls, the plug-in comes with an array of additional helpers: Advanced preset management, undo/redo, quick A/B comparison, copy & paste, an online help, editable labels, mouse-wheel support and much more.

SlickEQ is a collaborative project by Variety Of Sound (Herbert Goldberg) and Tokyo Dawn Labs (Vladislav Goncharov and Fabien Schivre).

SlickEQ – some more release info

Just a couple of days ago we introduced the upcoming release of SlickEQ and lots of questions raised already. So, here is what Fabien already committed about it in a public forum:

  • Win/Mac, AU/VST2/VST3 (+AAX planned and in process), x32/x64
  • No linux builds planned, sorry.
  • The name is “TDR VOS Slick EQ” and it will be available for free.
  • Release is a matter of days. Maybe a week or two.

As of today I just want to add: With the introduction of TDR VOS SlickEQ, quite a number of amazing and previously unheard DSP algorithms will see the light of day – including (but not limited to) several Stateful Saturation algorithms running within an audio signal path entirely upsampled to a constant high sample rate for maximum precision.

Expect smoothness, best-in-class.
