The Logic7 algorithm creates a 7.1 surround upmix from a stereo (or dual mono) audio signal. <\/span>This object upmixes two-channel stereo (or dual mono) audio inputs to seven main outputs (L\/R Front, Center, L\/R Side, L\/R Rear).
\nThe algorithm consists of a steering angle calculator from the input signal. A matrix mixer generates the surround channels by mixing input Left and Right channels weighted by adaptive gains calculated from the steering angle. All pass filters adjust the phases between Left & Right pairs of generated surround channels and Shelving filters are applied.<\/span><\/p>\n
