Abstract:
A method and system are implemented in a stereo sound signal encoding system for time domain down mixing right and left channels of an input stereo sound signal into primary and secondary channels. Correlation of the primary and secondary channels of previous frames is determined, and an out-of-phase condition of the left and right channels is detected based on the correlation of the primary and secondary channels of the previous frames. The left and right channels are time domain down mixed, as a function of the detection, to produce the primary and secondary channels using a factor β, wherein the factor β determines respective contributions of the left and right channels upon production of the primary and secondary channels.

Claim (Index 18):
A system for time domain down mixing right and left channels of an input stereo sound signal into primary and secondary channels, comprising:\n at least one processor; and a memory coupled to the processor and comprising non-transitory instructions that when executed cause the processor to implement:\n a calculator of correlation of the primary and secondary channels of previous frames; \n a detector of an out-of-phase condition of left and right channels based on the correlation of the primary and secondary channels of the previous frames; and \n a time domain down channel mixer for mixing, as a function of the detection, the left and right channels to produce the primary and secondary channels using a factor \u03b2, wherein the factor \u03b2 determines respective contributions of the left and right channels upon production of the primary and secondary channels.
