METHOD FOR ENCODING AND DECODING OBJECT-BASED AUDIO SIGNAL AND APPARATUS THEREOF

摘要

Methods and apparatuses for encoding and decoding an object-based audio signal are pro vided. The method of decoding an object-based audio signal includes extracting a down-mix signal and object-based parameter information from an input audio signal, generating an object- audio signal using the down-mix signal and the object-based parameter information, and generating an object audio signal with three-dimensional (3D) effects by applying 3D in¬ formation to the object audio signal. Accordingly, it is possible to localize a sound image for each object audio signal and thus provide a vivid sense of reality during the reproduction of object audio signals.
