FIELD: physics, acoustics.
SUBSTANCE: invention relates to encoding and decoding an audio signal in which audio samples for each object audio signal may be localised in any required position. In the method and device for encoding an audio signal and in the method and device for decoding an audio signal, audio signals may be encoded or decoded such that audio samples may be localised in any required position for each object audio signal. The method of decoding an audio signal includes extracting from the audio signal a downmix signal and object-oriented additional information; generating channel-oriented additional information based on the object-oriented additional information and control information for reproducing the downmix signal; processing the downmix signal using a decorrelated channel signal; and generating a multichannel audio signal using the processed downmix signal and the channel-oriented additional information.
EFFECT: high accuracy of reproducing object audio signals.
