## What is RRS Fuse Stereo Image?

RRS Fuse Stereo Image AUv3 plug-in — comes as time-limited Demo-version for you to try. It gives you 5 minutes of Free play time. (You can reload the RRS Fuse Stereo Image AUv3 plug-in as many times as you want, thereby you get the Demo period again and again.) Unlimited version of RRS Fuse Stereo Image AUv3 plug-in comes as In-App Purchase.

To use RRS Fuse Stereo Image as a plug-in, you need an AUv3-compatible host app like GarageBand, Auria, AUM, Cubasis and more — RRS Fuse Stereo Image will appear in the list of Audio Unit extensions for effect plug-ins in the host app.

This circuit utilises a technique that separates a stereo signal into two channels: a sum (L+R) for the sounds in the center (M) and a difference signal (L-R) for the sounds on the left and right (S) allowing you to narrow or widen the stereo image using the WIDTH control. The SPACE circuit is a frequency-dependent width control based on the concept of Stereo Shuffling, allowing you to inject interesting depth effects into your mix. Now in your DAW!

RRS Fuse Stereo Image exposes a brand new SHUFFLE control for changing the frequency cut-off in the SPACE circuit, exposes insight into the stereo field of the signal using the built-in polar sample phase correlation meter, and lets you easily audition the stereo field of the signal using the SOLO SIDE feature – combine this with the RRS Plug-in Engine A/B-ing feature to hear just what a difference RRS Fuse Stereo Image can make to your mixes.

Features:

• Based on a concept that has roots in EMI engineer Alan Blumlein's invention of modern stereo in 1931: Stereo Shuffling;
• WIDTH control lets you increase the level of the side signal to narrow or widen the stereo image;
• SPACE control allows you to experiment with a broad bass-frequency boost or cut in the side signal;
• SHUFFLE parameter allows additional tweaking to the frequency cut-off in the SPACE circuit;
• Use SOLO SIDE to easily audition the stereo component of the signal;
• Easily drop the input and output meters into mid-side side mode using the «M/S» toggles;
• Built-in UNDO/REDO support.

### 5/5 — Excellent

*2025-03-23*

Works as advertised. Needs stereo signal…duh! Wonderful freaking plug-in! I like to use one guitar in a track, but I wanted a good stereo-izer. Tried a bunch. They all left something to be desired. Now my single performance guitar tracks sound pro. Thank you! 10 STARS

### 5/5 — Another quality RRS plugin

*2023-06-18*

Unlike other wideners which can cause audible phasing this is really transparent. 
Well worth it.

### 1/5 — Somethings wrong
