Plugin Alliance TBTECH Kirchhoff-EQ v1.7.0 [MacOSX]

Kirchhoff-EQ is an ultimate 32-band parametric EQ plugin built for all critical professional applications. It has refined sound quality, analogue-matched curves, 15 filter types with continuously variable shape and 32 vintage EQ types modeled from real-world devices. The builtin dynamic processing functions are highly flexible and have ultra-low distorion. All these push Kirchhoff-EQ to a next-generation standard.

Q will never be the same again

Kirchhoff-EQ is the ultimate 32-band parametric EQ plugin, built for critical professional applications. It features refined sound quality, analog modeled curves, ultra-low distortion dynamics processing, 15 filter types (with continuously variable shape) and 32 vintage EQ types that emulate real-world devices.

The ultimate in sound quality

With its “Robust Nyquist-matched Transform”, Kirchhoff-EQ has made its digitally modeled frequency response more closely match its analogue counterparts, without the high frequency “cramping” found in regular IIR (infinite impulse response) equalizers.

High-precision processing

Sporting 64-bit operation by default, Kirchhoff-EQ uses a technique called “Double-Double” to make the precision of internal processing reach 117 bits! This is the first equalizer in the world to reach such precision. A technology called “Psychoacoustic Adaptive Filter Topologies” allows filter structures to intelligently change themselves to their “best fitting” state, resulting in optimized sound quality without tradeoffs in low or high frequencies.

A full palette of analog and digital filter types

Kirchhoff-EQ includes 15 unique filter types from conventional low pass, high pass, bell and shelving filters to more esoteric flat tilt, flat top and “sword” filters. Take advantage of 9 precisely matched vintage EQ models and fully variable EQ points not found in the analog domain.

Selectable phase modes

To meet all your phase relationship needs, the phase mode of Kirchhoff-EQ is switchable between zero-latency mode, analog mode, linear phase mode and an ingenious mixed phase mode that uses zero-latency when the band frequency point is low, and uses linear phase when it is high.

Deep and powerful dynamic EQ capabilities

Dynamics processing in the Kirchhoff-EQ are not just a bonus – they provide some of the richest dynamics features you have ever seen. With two-way thresholds, adjustable “onset” control and a relative detection option, you can do things other EQs simply can’t: Simultaneously compress and expand to help “stabilize” a given frequency. EQ transients separately from body. Or, effectively sidechain one frequency band to the dynamic activity in another. Even the vintage-modeled curves can be applied to the dynamics processing.

Endless features and intuitive operation

Kirchhoff-EQ has every feature you could imagine in an EQ including spectrum grab, oversampling, lookahead, mid-side processing and monitoring, stereo width, global EQ scaling and more, all optimized for ultra low CPU workload.
