01Overview

RSPhaseShifter is built around a phase-shift topology modeled on the Phase Shifter W2324 analogue hardware, developed with Roger Schult and German Audio Lab. MAAT describes it as a digital implementation of that circuit rather than a simulation, and it is aimed at engineers who need to align sources that compete with each other. The plugin offers a stepped or continuous frequency control, a phase angle range, and gain refinement, with mirror, flip and delta modes for stereo work.

Phase Angle, Frequency and Stereo Controls

The range switch selects between 0 to 180 degrees, bypass, and 180 to 360 degrees. The phase angle is continuously adjustable from 15 to 180 degrees, and the resonant frequency is chosen with a 13-step ELMA-style control covering 16 Hz to 4 kHz. The frequency control can be stepped for repeatability or continuous.

MIRROR and FLIP modes speed up stereo setting selection, and the DELTA mode changes stereo spread in an MS workflow. Gain is adjustable from -5 to +5 dB in 41 steps. Bypass lets you compare the processed signal with the unprocessed source directly.

Typical Uses for Phase Alignment

The developer lists post-production, stem mastering, outboard gear compensation, film re-recording, live production, sound reinforcement, and content creation for gaming and VR as uses that benefit from the plugin.

A common application is running the plugin on one channel of a stereo ambience pair that picks up a localized source at slightly different distances. Multi-mic sources such as a snare with top and bottom mics, or an acoustic guitar with a microphone and a piezo pickup, can also be aligned by adjusting the phase on the feed closest to the source.
