METHOD AND APPARATUS FOR ENCODING AND DECODING OBJECT-BASED AUDIO SIGNAL Russian patent published in 2013 - IPC G10L19/08 

FIELD: information technology.

SUBSTANCE: audio decoding method involves extracting from the audio signal a first audio signal wherein one or more music objects are grouped and encoded, a second audio signal wherein at least two vocal objects are grouped step by step and encoded, and a residual signal which corresponds to the second audio signal, and generating a third audio signal using at least one of the first and second audio signals and the residual signal. A multichannel audio signal is then generated using the third audio signal. Thereafter, multiple playback modes can be efficiently provided.

EFFECT: audio signal encoding and decoding, where object audio signals with an associative link are packeted into one group and can then be processed on a subgroup basis so that multiple playback modes can be processed through it.
