Stereo Touch is a free stereo imaging VST, VST3, Audio Unit, AAX plugin developed by Voxengo. Compatible OS(s): Windows 64b, macOS.
Stereo Touch can be used to add stereo width to audio tracks. This plug-in is most effective on mono pad sounds and alike. This effect works with mono stream generating stereo stream. It also works with stereo streams, however both channels get processed independently of each other like they are mono streams and then two resulting stereo streams get mixed together to produce one stereo stream.
