Mooni DSP Mooni Stereo Widener & Filter WIN VST3 [FREE]

Mooni Wider by Mooni DSP is a free stereo widener and filter effect for Windows, supplied in VST3 format. It is aimed at home producers and mix engineers who want to adjust stereo spread, shape frequencies, and position sounds without loading several separate effects.

The interface combines three sections. An XY filter area provides low-pass and high-pass filtering alongside panning, frequency adjustment, and left/right solo controls. The width section lets you move a stereo signal toward mono or expand its spread, with automatic gain control. A single analog-style VU meter can display either input or output level, with adjustable gain and calibration controls.

Use Mooni Wider when a stereo part needs a narrower focus, a broader image, or some filtering to help it fit into a mix. It suits Windows setups running VST3-compatible hosts such as FL Studio and Ableton Live; it is not a Logic Pro plugin. To install, extract the ZIP, place Mooni_Wider.vst3 in C:Program FilesCommon FilesVST3, then rescan plugins in your DAW. The listed download size is 8 MB.
