ABSTRACT:
A method of mixing audio channels is effective at rebalancing the audio without introducing unwanted artifacts or overly softening the discrete presentation of the original audio. This is accomplished between any two or more input channels by processing the audio channels to generate one or more “correlated” audio signals for each pair of input channels. The in-phase correlated signal representing content in both channels that is the same or very similar with little or no phase or time delay is mixed with the input channels. The present approach may also generate an out-of-phase correlated signal (same or similar signals with appreciable time or phase delay) that is typically discarded and a pair of independent signals (signals not present in the other input channel) that may be mixed with the input channels. The provision of both the in-phase correlated signal and the pair of independent signals makes the present approach well suited for the downmixing of audio channels as well.
