Abstract:
A method includes generating a windowed time-domain mid channel by applying two first asymmetric windows to a first frame of a time-domain mid channel and applying two second asymmetric windows to a second frame of the time-domain mid channel. The method includes transforming the windowed time-domain mid channel to a transform domain to generate sets of transform-domain mid channel data including first transform-domain mid channel data corresponding to a first mid channel window of the first frame and second transform-domain mid channel data corresponding to a second mid channel window of the first frame. The method includes performing an up-mix operation using the sets of transform-domain mid channel data, stereo parameters from the bit stream, and an interpolated parameter determined using an unevenly weighted interpolation between a first stereo parameter value associated with the first frame and a second stereo parameter value associated with the second frame.

Claim (Index 27):
The method of  claim 23 , further comprising:\n determining a second interpolated stereo parameter value for the second mid channel window based on a sum of a third product and a fourth product, the third product based on a third interpolation weight and the first stereo parameter value, and the fourth product based on a fourth interpolation weight and the second stereo parameter value, the third interpolation weight greater than or equal to the first interpolation weight, and the fourth interpolation weight less than the second interpolation weight; and applying the second interpolated stereo parameter value to the second mid channel window during the up-mix operation.
