FIELD: physics.
SUBSTANCE: group of inventions provides for irregular quantization of parametres related to parametric spatial coding of audio signals, and also provides restoration of an audio signal in a sound decoding system that takes into account irregular quantized parameters. According to the invention, such an approach makes it possible to reduce bit costs without significantly reducing the quality of the reconstructed audio signal.
EFFECT: increasing the efficiency and quality of the encoding of the audio signal.
