Abstract:
A stereo sound signal encoding method and system for time domain down mixing right and left channels of an input stereo sound signal into primary and secondary channels, determine normalised correlations of the left channel and right channel in relation to a monophonic signal version of the sound. A long-term correlation difference is determined on the basis of the normalised correlation of the left channel and the normalised correlation of the right channel. The long-term correlation difference is converted into a factor β, and the left and right channels are mixed to produce the primary and secondary channels using the 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 6):
A time domain down mixing method as defined in  claim 1 , wherein the factor \u03b2 represents both (a) respective contributions of the left and right channels to the primary channel and (b) an energy scaling factor to apply to the primary channel to obtain a monophonic signal version of the sound.
