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 23):
The method of  claim 22 , further comprising:\n determining a first interpolated stereo parameter value for the first mid channel window based on a sum of a first product and a second product, the first product based on a first interpolation weight and the first stereo parameter value, the second product based on a second interpolation weight and the second stereo parameter value, wherein the first interpolation weight is not equal to the second interpolation weight; and applying the first interpolated stereo parameter value to the first mid channel window during the up-mix operation.
