Encoder, Decoder and Methods for Spatial audio Object Coding multiresolution compatible Reverse

摘要

A Decoder is provided for generating an audio signal without mixture that includes a Plurality of audio channels not mixed. In addition, we provide an encoder and an encoded audio signal.The Decoder comprises a mixture of information without a determiner for determining information without mixture through the reception of First Parametric Side information on at least one Second Object audio signal and Parametric Side information on at least A Signal of audio object.Where the frequency Resolution of the second Parametric Side information is higher than the frequency Resolution of the first Parametric Side information.Further, the Decoder includes a module not loaded to the application of the information without mixture on a Down Mix Signal, so as to indicate a downward Mixing of at least one Object audio signal to obtain an audio signal Mixed co Mprende The Plurality of audio channels not mixed.The determiner information without mixture is configured to determine the information without mixture through the modification of the First Information and the second information Parametric Parametric with the purpose of obtaining information and Parametric modifiedSo information has a modified Parametric Frequency resolution that is higher than the first Frequency resolution.
