Abstract:
The invention provides methods and apparatuses for encoding a stereo audio signal having a left channel and a right channel. The apparatus includes a prediction coefficient estimator, downmixer, and multiplexer. The encoder is configured operate either in a prediction mode or a non-prediction mode.

Claim (Index 11):
An apparatus for encoding a stereo audio signal having a left channel and a right channel, the apparatus comprising:\n an estimator for generating a prediction coefficient using the left channel and the right channel; a downmixer for mixing the left channel and the right channel to produce a mid signal and a residual signal using the prediction coefficient; and a multiplexer for combining the mid signal, the residual signal, and the prediction coefficient to generate an audio bitstream, wherein the prediction coefficient minimizes an energy of the residual signal, and the encoding operates in either a prediction mode or a non-prediction mode for a time frame based on a value of the prediction coefficient, wherein the encoding operates in the non-prediction mode when the value of the prediction coefficient is zero.
