METHOD AND APPARATUS TO ENCODE AND DECODE MULTI-CHANNEL AUDIO SIGNALS |
摘要 |
An encoder (100) for encoding a multi-channel audio signal comprises a prediction processor (101) for generating two residual signals for two signal components of the multi-channel signal by linear prediction which is associated with psycho-acoustic characteristics and which specifically uses psycho-acoustic prediction filters; a rotation processor (105) for rotating the combined signal of the two residual signals to generate a main signal and a side signal, in which the energy of the main signal is maximized and the energy of the side signal is minimized; an encoding processor (109) for encoding the main and preferably the side signal; and an output processor (111) for generating an output signal data, prediction parameters and rotation parameters. |
