A Multichannel Surround Audio Format Applying 3D Sound Technology

摘要

As systems employing multichannel audio more and more, it is necessary to consider the surround soundcapability in the process of the sound recording and playing. This paper presents a structured audio format andits application to design more efficient surround sound system. 3D sound technology is used for localization ofsound source. We defined the reusable sound object to clarify the audio format. Sound object is a unit ofrecorded sound samples that can be changed by various effect properties. Filter and 3D property are applied tochange the sound objects in each track.
