The Stereoizer by NUGEN Audio is a stereo image manipulation plug-in that can be used in mastering, mixing, sound design and other applications. It is compatible with Mac and Windows and requires use of a host program that supports RTAS, VST or AU plug-ins.

The Stereoizer plug-in is intended to give you control over the stereo spread and depth existing within stereo tracks, and also to add width to mono tracks. It is designed to manipulate the stereo image yet maintain a natural sound without adding unwanted artifacts into your mix. The software does this by utilizing specialized algorithms that are designed to manipulate two naturally occurring localization cues that the ear uses to perceive location - IID (Inter-aural Intensity Difference) and the ITD (Inter-aural Time Difference).
