ABSTRACT:
A method for mixing source audio signals and an audio signal mixing system including a spectral content analyzer to determine the spectral content of input audio signals and to arrange the spectral content of the respective input audio signals into a plurality of spectral bands. Based on the determined energy levels in each of the spectral bands of the respective input audio signals, the audio signal mixing system modifies the energy levels corresponding to one of the input audio signals in a predetermined manner. In essence, the system looks at the spectral data content corresponding to each input audio signal (for example first and second audio input signals) and carves energy out of the energy levels of one of those spectral data signals in the spectral bands where the other spectral data signal has energy levels. The combination of the carved-out spectral data signal with the untouched spectral data signal yields a cleaner overall signal as a result of reduction of competition for dominance of energy levels in predetermined spectral bands, and accordingly, less psychoacoustic masking.
