Multi-channel signal encoding method and encoder
A multi-channel signal encoding method and an encoder, where the encoding method includes obtaining a multi-channel signal of a current frame, determining an initial multi-channel parameter of the current frame, determining a difference parameter based on the initial multi-channel parameter of the current frame and multi-channel parameters of previous K frames of the current frame, where the difference parameter represents a difference between the initial multi-channel parameter of the current frame and the multi-channel parameters of the previous K frames, and K is an integer greater than or equal to one, determining a multi-channel parameter of the current frame based on the difference parameter and a characteristic parameter of the current frame, and encoding the multi-channel signal based on the multi-channel parameter of the current frame. Hence, the method and the encoder ensure better accuracy of inter-channel information of a multi-channel signal. |

Audio encoder with selectable L/R or M/S coding
Methods and systems encoding a stereo audio signal having a left channel and a right channel are disclosed. The system includes a downmixer for generating a downmix signal and a residual signal from the stereo audio signal in selected frequency bands representing only part of a used audio frequency range of the stereo audio signal, and a decision module for selecting, in a time variant manner, either left/right perceptual encoding or mid/side perceptual encoding. The system also includes a parameter estimator for estimating stereo parameters for reconstructing a stereo image of a portion of the stereo audio signal, and a perceptual encoder for performing either left/right perceptual encoding or mid/side perceptual encoding based on the selecting to generate an encoded output signal.
