METHOD AND DEVICE FOR PROCESSING AUDIO SIGNAL

摘要

The present invention relates to a method and device for encoding or decoding an object audio signal or rendering the object audio signal in a three-dimensional space. The method for processing an audio signal, according to one aspect of the present invention, comprises the steps of: generating a first object signal group and a second object signal group obtained by classifying a plurality of object signals according to a determined method; generating a first down-mix signal for the first object signal group; generating a second down-mix signal for the second object signal group; generating first object extraction information in correspondence with the first down-mix signal with respect to object signals included in the first object signal group; and generating second object extraction information in correspondence with the second down-mix signal with respect to object signals included in the second object signal group.

主权项

1. An audio signal processing method, comprising:
receiving a plurality of downmix signals including a first downmix signal and a second downmix signal; receiving first object extraction information for a first object signal group corresponding to the first downmix signal; receiving second object extraction information for a second object signal group corresponding to the second downmix signal; generating object signals belonging to the first object signal group using the first downmix signal and the first object extraction information; and generating object signals belonging to the second object signal group using the second downmix signal and the second object extraction information.
