Plugin
MS Widener
Widen the stereo image without losing mono compatibility.
Most widener plugins are a single knob that either does nothing or falls apart the moment someone checks the mix in mono. This one splits the difference: width is applied above a bass crossover, so the low end stays centered and phase-safe while everything above it opens up. It's free because it's also the plugin that shows you what mid/side actually looks like before you commit to the paid ones — the built-in goniometer plots the stereo field in real time as you turn the knob, so width stops being something you only hear and starts being something you can see.

Controls
Width
0 to 200%. Above 100% widens past the source material's natural stereo spread; below 100% narrows toward mono.
Mono Beneath
Sets a crossover frequency below which the signal collapses to mono, so bass stays centered no matter how wide the top end gets.
Huge
A more aggressive widening character for material that can take it — further from the source, more obviously processed.
Bass Monitor
Solos the mono-collapsed low end on its own, so you can check exactly what's happening below the crossover.
What it does

- Mono Beneath collapses low frequencies to mono below a set crossover, so bass stays centered
- Retro and Huge modes for two different widening characters
- Built-in goniometer shows the stereo field and channel correlation in real time
- Bass Monitor auditions the mono-collapsed low end on its own
