What it is

The Ocelot Upmixer is a stereo imaging plugin from Fuse Audio Labs that converts mono sources into natural-sounding stereo using spectral diffusion technology. It's designed to add width and depth without phase artifacts, keeping the result fully mono compatible. The developer behind it - Reimund Dratwa - has DSP credits on respected analog-modeled brands including Elysia, Millennia, Neold, and Vertigo.

Who it's for

Mix engineers and producers who regularly work with mono sources - drum room mics, old samples, mono synths, voiceovers - and need to place them convincingly in a stereo field without comb filtering or phasing issues.

Key features

• Spectral diffusion engine converts mono to stereo with no audible artifacts and full mono compatibility
• A Tune dial lets you match the tone of the upmixed signal to the character of the source
• High- and low-pass filters give you surgical control over which frequencies get widened
• Built-in vector scope and correlation meters let you monitor the stereo image in real time
