Ozone Imager 2 ((free)) Direct

The Verdict in a Nutshell

Ozone Imager 2 is arguably the most essential free plugin available for music production. While it has limitations—specifically regarding mix translation on mono systems—it offers a visual interface and a sound quality that punches miles above its $0 price tag. If you don’t have a stereo imaging tool in your arsenal yet, download this immediately.

Pros

• Easy to learn; low barrier to entry.
• Clear visualizations with sensible default color ramps.
• Fast access to ozone/UV products for education and outreach.
• Lightweight — runs well in standard browsers.

• On the master channel, push the width slider to 5-15% max.
• Use the vectorscope to check if your mix is already balanced.
• If the correlation meter dips below 0, reduce the width or use M/S EQ to mono the low-end (below 100Hz) before the Imager.

2. Crystal Clear Vector Scope The real-time vectorscope (the bouncing green blob) is the star of the show. It shows you exactly how wide (or narrow) your stereo field is in real-time. ozone imager 2
