Ozone Imager 2 is a free stereo imaging plugin used in audio production, mixing, and mastering. It is the "lite" version of the Imager module found in iZotope’s flagship Ozone mastering suite. Despite being free, it has become an industry standard tool due to its visual feedback and precise control over the stereo field.
Its primary function is to visualize the stereo width of an audio signal and allow the user to widen or narrow that width. It is available in VST, VST3, AU, and AAX formats, making it compatible with almost all major Digital Audio Workstations (DAWs).
This is the heart of the plugin. The large central slider allows you to increase the stereo width of your signal from 0% (normal stereo) up to 200% or even 400% (extremely wide).
How it works: It uses a Mid/Side (M/S) processing algorithm. The "Mid" signal (information common to both left and right channels) remains centered. The "Side" signal (information unique to each channel) is amplified. As you increase the width, the Side signal gets louder relative to the Mid, creating the illusion of a broader soundstage.
Ozone Imager 2 is frequently placed on the master bus at the end of a chain.
On Master Bus (Mastering): This is where the plugin shines. If your mix feels a bit narrow, dialing the Width knob up to 110% or 120% can instantly add "air" and separation. It glues the mix together by pushing elements slightly wider, creating a more immersive listening experience.
On Individual Tracks:
Ozone Imager 2 is a polished, approachable visualization tool ideal for educators, communicators, and anyone needing fast, clear ozone and UV maps. It excels at accessibility and clarity but is intentionally lightweight — users requiring rigorous analysis or bulk data access will need to combine it with dedicated scientific tools.
