Combining the concept of M/S (Mid Side) matrix processing of the stereo field with multiband architecture, Quad Image effectively allows control over the stereo width of each frequency band. Its simple control set notwithstanding the Quad Image is a powerful processor. The M/S processing in each band allows complete control on the stereo image over selected frequencies. This can be either used to fix technical issues in mixes, where the relationship between center (M) and side (S) content may be wrong or may need tweaking in selected regions of the audio spectrum, or to perform creative effects like exaggerating the width of a stereo source, like a synth track, to generate cool and unusual stereo "tricks".
