This is a list of totally free vst plugins in the category stereo, dimension expander and midside plugins. The quality of these free stereo plugins are high thus I don’t see a real need to buy fancy expensive ones. But maybe you are that type of person, don’t let me tell you what to do! I don’t judge you for wanting the most fancy expensive dimension expander. Go for it!

Stereo plugins allow us to manipulate the stereo image of a sound. For example making a stereo audio file appear wider or narrower using the dimension expander; Isolating mid or side information of a stereo track. This very helpful in the mastering phase of a production;  Or simply displaying the stereo scope for a visual representation of the stereo field.
