SantaCruzEQ borrows the innovative code from both Algorithmix’s original PEQ Blue and our own thEQblue remix, wrapping it in a modern, higher fidelity environment designed to help you be more productive.

• The most complete collection of classic analog equalizer emulations
• Six or twelve different equalizer types; in total, 10 serial & 2 parallel
• Up to 12 PEQ styles for every job: classic, vintage, modern and unconventional
• Different Q characteristics: classic, constant–Q, proportional, ideal–Q and special
• True high resolution emulation of analog equalizers, not modeling: no added noise, distortion or other non–linearities
• Support for up to 384 kHz sample rate, suitable for HRA and game production and 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 +6.02 dB of gain and Q of 0.71, ideal for quick comparisons between types
• Six Sections total, with four having freely assignable parametric filter variants: bell; multi–order high & low shelf; multi–order high & low cut
• “Outer” Sections, the first and last, offer multi–order high & low shelf and multi–order high & low 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 bell filters
• Adjustable slope 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
• Insane 80 bit “long double” precision internals virtually eliminate rounding errors and resulting distortion
• Resizable and zoomable frequency response graphing for precise adjustments
• Parameter editing via numerical fields or directly on the Graph
• Presets for quick setup comparison
• Several instances, each with different PEQ architectures, can be opened simultaneously
• Band grouping function lets you simultaneously alter ƒ, Q and gain for multiple Sections
• ƒ lock function when you’ve found your resonant frequency and want to alter just Q or gain
• True Peak metering alerts you to TP overs
• Sort button rearranges Sections in order, from low to high ƒ, with a single click

Session Compatibility between SantaCruzEQ12 and SantaCruzEQ6

Session interchange between the two versions can take two forms:
• Scenario A: A colleague uses instances of SantaCruzEQ6 in a DAW session, then sends the session to a colleague with SantaCruzEQ12. — All instances will open and work correctly.
• Scenario B: A colleague uses instances of SantaCruzEQ12 in a DAW session, then sends the session to a colleague with SantaCruzEQ6. — This scenario is only slightly more complicated…If the sender restricts their use to Architectures No. 1 through 6, then all instances will open as saved. If however, the sender uses Architectures No 7-12 in a saved session and sends that to their colleague, it will “snap” to Architecture No. 1 and may/will need to be remapped.

Features

• Four fully parametric minimum–phase Sections for complete versatility
• Two Sections with parametric shelving or cut topologies for high or low frequency control
• 80 bit internal precision blows away the competition for sound quality
• Up to twelve unique idealized Architectures, derived from analog circuitry
• Broad choice of cut, shelf and bell topologies
• AutoGain for effortless A/B comparisons
• Proprietary oversampling for “analog” sound at 44.1 and 48k

Supporting

• AAX Native (Pro Tools 10.3.10 and newer), AU, VST 2, VST 3
• Sample rates from 44.1 to 384 kHz
