GrandEQ is nothing else but the culmination of what DDMF have learned in the years since their first software EQ was released back in 2006. It represents the state of the art of equalizer algorithms.

The goal in digital equalizer design is always to reduce the amount of digital artefacts which are introduced due to the necessarily finite sampling frequency. In its minimum phase setting, GrandEQ manages to do just that to an extent larger than most other EQs, and notably both in the amplitude and in the phase domain, while introducing only a very small amount of latency. The result is a very open and clear sound with, at the same time, excellent CPU efficiency. Its linear phase setting stays completely in the time domain, using an elaborate time-reversal algorithm and 2-fold oversampling to ensure excellent amplitude and (flat) phase response with the lowest possible amount of digital distortion.

Features:

  • Minimum Phase algorithm: accurate magnitude and phase matching to analog targets.
  • Linear Phase algorithm: forward-backward approach + oversampling.
  • 7 independent bands, with 7 different band types: Bell, Low Shelf, High Shelf, Low Cut, High Cut, Bandpass and Notch.
  • two internal states (A/B) for quick switching between alternative settings.
  • Left-Right or Mid-Side operation.
  • Two-channel EQ which can be linked/unlinked.

I tried this out as an alternative to some digital EQ's that I was never quite satisfied with in the very top end (probably 3 kHz and up).

In demo'ing it to be honest I was hoping not to like it - because I've paid a few hundred dollars on EQ's at this point, and could never get what I was hoping for out of them at the aforementioned very top end.

It seemed like making any adjustment at all in this range, where all the analog magic of a lead guitar tone lives, was going to alter it in an unwanted way. For example, a cut using a 6db slope and gentle Q would still seem to change the "color" I was hearing, and remove something very desirable that I was hoping to only slightly subdue.

Then after creating a number of presets for everything to lead guitar, to piano, to synths, to drums, (using the mixed mode), I concluded that I like the clarity that remains with this - it's given me a new standard for the word "transparency" when applied to an EQ.

The reason for this benefit is not plain to me, but it may have to do with something about the minimum phase mode keeping amplitude intact across the spectrum. The alternatives would be an EQ that alters the phase, or one that has tons of latency. This mode, however, is low enough on CPU, but perhaps accurate enough in terms of phase and amplitude (a pretty esoteric subject that Dan Worrell should visualize for me!).

I love the purchase and gave it 5 stars because I don't have another EQ that beats the sound of this, including from Fabfilter, Meldaproductions, DMG (Equilibrium - haven't tried Multiplicity yet), Threebody Tech, Eventide, Voxengo, and several from Plugin Alliance (I have the bx hybrid - which comes close but isn't as "clean" in terms of being digital in my understanding; and I have the digital v3, as well as the Amek 200).
