OBJECT-BASED AUDIO CONTENTS GENERATION/PLAYBACK APPARATUS CAPABLE OF PLAYING A OBJECT-BASED AUDIO CONTENTS BASED ON ONE AMONG A SOUND FIELD SYNTHESIS PLAYBACK MODE AND A MULTI CHANNEL SURROUND PLAYBACK MODE AT LEAST

摘要

PURPOSE: An object-based audio contents generation/playback apparatus is provided to generate the object-based audio contents by encoding one among a plurality of object audio signals, record space information, sound source location information and a multi-channel audio signal at least.;CONSTITUTION: An object audio signal gaining unit(110) gains a plurality of object audio signals by recording a plurality of sound source signals. A record space information gaining unit(130) gains the record space information toward the record space of sound source signals. A sound source location information gaining unit(120) gains the sound source location information of the sound source signals. An encoder(140) generates a object-based audio contents by encoding one among a plurality of object audio signals, the record space information and the sound source location information at least.;COPYRIGHT KIPO 2010
