SideShape Mono-Compatible Stereo Expander

SideShape is a highly advanced “Mono-Compatible” stereo expander designed to push the boundaries of your mix without destroying its phase.

Unlike traditional stereo wideners that rely on simple delays or Haas effects—causing your sounds to completely disappear when played on a mono speaker or smartphone—SideShape utilizes a complex network of All-Pass filters. It injects massive, larger-than-life spatial information into the sides while guaranteeing your original signal remains 100% intact when summed to mono.

Features:

Mono-Compatible Widening: Push the width from 100% up to 200% for an ultra-wide stereo field. If your track is played in mono, the spatial effect perfectly cancels out, leaving your mix completely safe and punchy.

Low Cut Filter (20Hz – 500Hz): Never lose your low-end focus. The built-in high-pass filter ensures that your kick drums and sub-basses remain solidly anchored in the center, only widening the mid and high frequencies.

Dry/Wet Mix: Blend the expanded signal perfectly with your original track. Ideal for parallel processing or adding just a subtle touch of space.

Dynamic Correlation Meter: Keep an eye on your phase health. The photorealistic correlation meter gives you instant visual feedback, ensuring your stereo image stays healthy and green.

Compatibility: Windows (64-bit) VST3. Compatible with FL Studio, Ableton Live, Studio One, Reaper, Logic Pro, Cubase, etc.
