RSPhaseShifter

High Fidelity Phase Rotator

The only official digital implementation of Roger Schult/German Audio Lab’s Phase Shifter W2324 pure analog hardware.

Analog Soul, Digital Heart

Creating a very high fidelity, phase shifted version of the input, RSPhaseShifter provides a fast, convenient and musical means of aligning individual mix elements for best subjective result. RSPhaseShifter is great for any situation where you need to creatively control tonality, power spectrum and harmonic content through phase manipulation. Post–production, stem mastering, outboard gear compensation, film re–recording, “live” production, sound reinforcement, along with content creation for gaming and VR all benefit from having RSPhaseShifter on hand.

Old Skool Values

RSPhaseShifter was created in conjunction with Roger Schult/German Audio Lab, and is a painstaking, 64 bit digital realization of Schult’s trusted Phase Shifter W2324 analog phase rotator hardware. When multiple sources compete rather than complement, RSPhaseShifter should be your choice for a fast, intuitive, easy to use and effective remedy.

Simple Yet Versatile

RSPhaseShifter: a mixer’s secret weapon, both live and in the studio…Whether it’s mix sessions with multiple tracks of one instrument, or alignment of spots and overheads, RSPhaseShifter makes quick work of cancellation issues, bringing back the richness and impact you cannot get from basic delay compensation. Match and optimize the time delay or phase response of a subwoofer in a surround monitoring environment, address fold–down issues or create thick, ultra–wide sounds and phase sweeps by deliberately manipulating phase of one side of a stereo track.

Purpose–built

RSPhaseShifter’s analog–style controls are no accident. They’re the same controls found on the tried and true Phase Shifter W2324 hardware, only better. With no added noise, double precision internal processing plus support for AAX and 8x sample rates, RSPhaseShifter is a cost effective addition to any engineer’s toolkit.

Better By Design

As with all Roger Schult by MAAT products, the RSPhaseShifter is hand crafted and precision engineered in California by way of Germany. This is an explicit digital recreation of the analog W2324 topology, not a modeling or simulation algorithm. They copied the functionality of the original hardware without analog’s shortcomings. This tool´s value is more about what it does technically, so they left out stuff like fake transformer color, hum or Johnson Noise. There are lots of colorful plug–ins, Maat simply provide convenient access to the useful functionality along with a classic API Lunchbox look.
