Abstract: An audio track mixing processor comprising phonic conversion circuitry for receiving a primary audio track of an input audio mix in stereo and transmitting a detector activation signal in mono; a plurality of root mean square detectors tuned to consecutive midrange frequencies and each receiving the detector activation signal and each transmitting a gain control signal based upon the detector activation signal; a plurality of gain reduction amplifiers each tuned to the same consecutive midrange frequencies as the root mean square detectors and each receiving the secondary audio track of an input audio mix and the gain control signal, and each transmitting a first modified secondary audio track based upon the gain control signal; a bypass filter for receiving the secondary audio track of an input audio mix and transmitting a second modified secondary audio track; and summation circuitry for receiving a primary audio track and the first and second modified secondary audio tracks and transmitting a summed result
