MAAT's mastering equaliser models the characteristics of 12 analogue EQ designs, but leaves out their real-world drawbacks!
Back in 2007 I reviewed Algorithmix's PEQ Blue EQ — www.soundonsound.com/reviews/algorithmix-peq-red-blue — and found it to be a great-sounding, very flexible minimum-phase EQ. It was eye-wateringly expensive, however, and Algorithmix seem to have faded from view; their website remains but hasn't been updated in years.
Thankfully, though, their Blue, Orange and Red equalisers have been taken on by MAAT and given a makeover, and while they could not be described as 'cheap', they are certainly more keenly priced than the Algorithmix versions. I don't know the precise connection between Algorithmix and MAAT, and can't be completely sure of the extent of the redevelopment which produced thEQblue (the manual is a tad coy about this) but correspondence with the development team tells me that they've done more than simply port the earlier Algorithmix code.
AAX (Pro Tools 10.3.10 and newer), AU, VST 2 and VST 3 plug‑in formats are supported, as are Mac OS (10.8 and later) and Windows (7 32- and 64-bit, and later), so most DAWs are catered for, and installation on my Windows 10/Sequoia 14 system was straightforward. There are a number of ways of activating the software; as Internet provision here on the Norfolk coast is best described as awful, I used the offline method of adding the licence to a Wibu USB dongle. Note, though, that the newest version of the software, which wasn't released at the time, no longer uses the Wibu. Instead, it allows for a cloud-based service which provides three licensing options. Online caters for users with modern Internet connections, temp offline would suit those with 'spotty' or non-super broadband, while full offline licensing is presumably designed for...
