ACL - M/S Matrix

The M/S Matrix module converts stereo material with left and right channel into the M/S format. – And vice versa. This allows users to transform conventional stereo signals into M/S material, process mid and side separately via external modules and then convert them back again. All inputs are equipped with volume controls, meaning any level changes occuring during editing can be easily compensated for. Typical examples of M/S processing are the delicate attenuation of the mid signal’s high frequencies via an equalizer or filtering low frequencies out of the sideband. - Maybe plus addition of gentle modulation effects. In combination, these techniques lead to a very wide, atmospheric stereo image. Of course, the M/S Matrix can be used for tons of other applications as well. How about a bitcrusher plus a delay only on the sideband, for example? – Just let your imagination run wild!

ACL’s M/S Matrix features two sections: The first stage comes equipped with audio inputs plus level controls for left and right stereo signals. Internally, the material is converted to the M/S format. Results are emitted via corresponding outputs. The second section works the other way round. Here users can feed in mid and side signals, edit their volume and convert them into the L/R format.
