One of the most venerable plug-ins around for working on your stereo image, the S1 uses psycho-acoustic spatial imaging techniques to enhance and alter stereo separation. By employing clever algorithms it lets you move your sound around in the stereo field, either widening it out across the left and right channels or focusing it more in the centre. Used on an individual sound this can help to enhance width, perhaps on a strummed guitar, or decrease it on a source like bass.
