Abstract:
The present disclosure provides methods, devices and computer program products for encoding and decoding of a vector of parameters in an audio coding system. The disclosure further relates to a method and apparatus for reconstructing an audio object in an audio decoding system. According to the disclosure, a modulo differential approach for coding and encoding a vector of a non-periodic quantity may improve the coding efficiency and provide encoders and decoders with less memory requirements. Moreover, an efficient method for encoding and decoding a sparse matrix is provided.

Claim (Index 10):
A method for reconstructing a time/frequency tile of an audio object in an audio decoding system, comprising:\n receiving a downmix signal comprising M channels; receiving at least one encoded element representing a subset of M elements of a row in an upmix matrix, each encoded element comprising a value and a position in the row in the upmix matrix, the position indicating one of the M channels of the downmix signal to which the encoded element corresponds; and reconstructing the time/frequency tile of the audio object from the downmix signal by forming a linear combination of the downmix channels that correspond to the at least one encoded element, wherein in said linear combination each downmix channel is multiplied by the value of its corresponding encoded element.
