MULTI-OBJECT AUDIO ENCODING AND DECODING METHOD AND APPARATUS THEREOF
摘要
<p>A method for encoding/decoding a multi-object and an apparatus therefor are provided to offer various audio services to a user, efficiently. The first down-mix generating unit(102) down-mixes a background object(BGO) and the first foreground object(FGO1) to generate the first down-mix signal and the first residual signal. The second down-mix generating unit(103) down-mixes the first down-mix signal and the second foreground object(FGO2) to generate the second down-mix signal and the second residual signal. A bit stream generating unit produces a bit stream including the down-mix signal and residual signal.</p>
