T-RackS QUAD IMAGE (Download)
Multi-Band Stereo Imager

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 nothwithstanding 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)   side (S) content may be wrong   may need tweaking in selected regions of the audio spectrum,   to perform creative effects like exagerating the width of a stereo source, like a synth track, to generate cool   unusual stereo "tricks".
As in the rest of the T-RackS Quad-Series processors, we made sure the quality of the filters used to perfor the band slitting was of the highest quality; in this context it was even more crucial as the M/S nature of the module has a close relationship with phase manipulation.
Being able to control the stereo width of a selected frequency band is a tremendous power: widening the high end while maintaining the bass content focused in the center,   doing the opposite, according to your needs.
