MAAT Inc. – SantaCruzEQ

SantaCruzEQ is an entry–level version of MAAT’s renowned thEQblue, a cross–platform plug–in for correction and aesthetic equalization of digital audio.

We wanted to lift analog to another level, so we reverse engineered a variety of well respected hardware EQs, creating idealized digital versions from that inspiration. Rather than models or simulations that carry analog baggage, SantaCruzEQ has no noise, distortion or other secondary effects inherited from analog.

SantaCruzEQ is a diverse collection of classic equalizer architectures, assembled into one package. You get precise, idealized examples of legendary analog equalizer circuitry, complemented by progressive new models. Whether it’s vintage, modern, or experimental, SantaCruzEQ is a sonic sandbox affordable by every mixing and mastering engineer.

Available for both Windows and macOS, SantaCruzEQ builds on the proven foundation of Algorithmix’s groundbreaking original, while bringing that reference quality into the 21st Century. SantaCruzEQ is a collection of six or twelve minimum phase equalizer architectures employing proprietary 80 bit floating point algorithms and sophisticated signal windowing to create a broad palette of exceptional sound qualities and characters.

• 80 bit internals virtually eliminate rounding errors
• Different Q characteristics: classic, constant–Q, proportional, ideal–Q and special
• True high resolution emulation of analog equalizers, not modeling
• Support for up to 384 kHz sample rate, suitable for HRA and game production & post
• Extended center frequency up to 80 kHz for filtering and correction in the ultrasonic
• Bell filters in all PEQ types are normalized to look identically at +6 dB of gain and Q of 0.71, ideal for quick comparisons between types
• Six sections with 5 freely assignable parametric filter variants: bell, low shelf, high shelf, low cut and high cut
• Extremely low noise and low nonlinear distortion algorithms result in residual THD+N significantly lower than 24 bit quantization noise
• Adjustable Q Factor for shelving and cut filters
• Multiple low and high cut filters can be overlapped to achieve brickwall slopes
• Very low noise and distortion upsampling for analog–like filters at baseband sample rates

In order to give you a choice of features and price, SantaCruzEQ is available in two versions:

• SantaCruzEQ6, with 6 architectures; №s 1 through 6
• SantaCruzEQ12, with all 12 architectures

SantaCruzEQ — A dozen precision variations on “analog,” all in one EQ. Beautiful series and parallel analog architectures that will take your work out of the ordinary.
