Linear Phase Without Compromise

When purity is paramount. tEQorange is a remedial linear phase EQ with unparalleled clarity. For mastering ears, and other discerning engineers.

A Dream Come True

Many mastering engineers, like MAAT founder Friedemann Tischmeyer, admired Algorithmix's original Linear Phase PEQ Orange. However, these EQs were only available as 32-bit VSTs for PCs, limiting their use as the industry evolved. Seeking alternatives, Tischmeyer explored options like EQuilibrium, recommended by colleague Bob Katz, but couldn't find a satisfactory replacement for the PEQ Orange. Thus, MAAT decided to reissue the PEQ Orange as a 64-bit plugin for all common formats and macOS. With input from Algorithmix fans and Tischmeyer's own ideas for UI improvements, the reissued PEQ Orange offers enhanced flexibility and speed. Unique features include the Contribution function, adjustable sonogram, and intuitive frequency adjustment. Additionally, a SORT button ensures filter sections remain in order even with multiple filters applied.

Unobtrusive Power

thEQorange offers a clean UI hiding powerful features. Unlike typical eye candy, it combines advanced functionalities in a single resizable window, enhancing productivity. Industry-first features, like freely assigning Sections to stereo or sum/difference, streamline workflow.

Subtle Functionality

Pristine fidelity and innovative UI design elevate thEQorange above its competitors in a once-unremarkable product category. With four monitoring modes, an ergonomic interface, intelligent monitor auto-gain, and exceptional sound quality, thEQorange is a must-try.

Better By Design

For precise repair, colorless correction, or baggage-free contouring, thEQorange's algorithm ensures linear phase correction. Use it for all your surgical equalizing needs effortlessly.

Features

• Exclusive Contribution Control™ — positive addition only, negative addition only, EQ contribution only, and “normal” EQ out helps to aurally keep track of your progress
• Proprietary algorithms result in extremely low noise and vanishingly small nonlinear distortion
• Unique EQ design results in no perceptible unwanted coloration with mixes (processing artifacts well below -100 dBFS) — work with clarity, transparency, and definition
• Equal delay at all frequencies regardless of filter settings, perfectly preserving the time relationship of harmonics in the original signal
• Operates at up to 384 kHz sampling rate, suitable for high resolution audio (HRA), DSD or DXD production and post
• Extended resonant or center frequencies up to 174.14 kHz, for processing in ultrasonic and near ultrasonic for all HRA production and post
• Exceptionally transparent ELF response, perfect for DC removal
• 12 sections with 5 freely assignable parametric filter types; bell, low shelf, high shelf, low cut, and high cut
• 5 freely assignable Panorama modes; stereo, mono (sum), L-R (difference), left–only and right–only
• 80 bit internals (long double floats) virtually eliminate rounding errors
• Adjustable Q for bell and high/low pass filters make musical adjustments easy
• Adjustable slope for shelving filters improve precision in the pass and stopbands
• Double the stopband attenuation (ripple) compared to other filter implementations
• Additional low and high pass filters can be overlapped to achieve steep “brickwall” slopes
• Special oversampling for reduced aliasing when working with baseband (44.1 & 48 kHz) sample rates
• Very low stop-band ripple
• No coloration or amplitude bumps even at very low frequencies
• Optional inbuilt tone generator makes for quick location of trouble spots
• SORT function organizes active Sections in ascending order
• TUNE function aligns center frequencies to Western tunings
• Sections have Solo and FLIP to quickly find and address trouble spots
• Grid snap toggles between surgical and musical applications, emulating popular hardware resonant frequency choices, including Maselec and Manley
• True Peak metering to avoid overs
• AutoGain for effortless A/B comparisons
• Resizable frequency response display for easy, high precision adjustments
• Exclusive dual view, monochrome/color real time spectrogram with user adjustable temporal wiper lets you choose “when” to transition to low clutter monochrome
• Choice of parametric editing via numerical fields or directly on the graphical display
• Complete setup exchange across multiple instances

Applications

thEQorange is a specialized mastering tool with rare forward/backward linear phase EQ capabilities. Its wide 80-bit double precision processing and fidelity-focused algorithm enhance transparency. With the features of Algorithmix’s LP PEQ Orange and more, it offers powerful processing and double precision I/O for:

• Mastering and remastering tasks on complex, high fidelity mixes
• Equalizing of instrumental group stereo sub–mixes
• Clarifying the midband and rescuing dense mixes
• Addressing resonances and peaky instruments without tonal degradation
• Tight, transparent low shelf and presence boosts
• Removing unwanted ultrasonic content from HRA recordings
• Identifying resonances with ease when sweeping, due to the low inherent ringing
• Putting mixes with too much DC or a super fat kick on a diet
• Tightening up loose or crowded mixes

thEQorange is not intended for tracking or mixing due to its high CPU demand and focus on mastering. Designed for the master buss, it excels at equalizing actual music, not artificial test signals. With its low channel count, it's not a lightweight plug-in but offers intricate algorithms for mastering tasks.
