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 22):
A time domain down mixing system as defined in  claim 20 , comprising:\n an energy analyzer for determining (a) an energy of each of the left and right channels, and (b) a long-term energy value of the left channel using the energy of the left channel and a long-term energy value of the right channel using the energy of the right channel; and an energy trend analyzer for determining a trend of the energy in the left channel using the long-term energy value of the left channel and a trend of the energy in the right channel using the long-term energy value of the right channel.
