Abstract
A method of decoding for an audio signal comprises the step of receiving a downmix of an audio signal, an object information, and a mix information, the object information including an object level information, an object correlation information, and an object gain information, generating a downmix processing information using the object information and the mix information, and processing the downmix of the audio signal using the downmix processing information. Various embodiments of the present invention provide a method and an apparatus for decoding multi-object audio signals fast and efficiently by reducing process time, computer resource, thereby relieving the resource requirement like the wide bandwidth. The object parameters according to the embodiments of the present invention can provide backward compatibility in the view of the channel-oriented decoding process.
