FIELD: physics, computer engineering.
SUBSTANCE: hardware unit for expanding a compressed audio signal into an expanded audio signal, comprising one or more expanded audio channels, including a parameter processing unit, configured to apply expansion parameters for expanding the compressed audio signal and obtain an expanded audio signal. The parameter processing unit is configured to apply phase shift to the compressed audio signal and obtain a phase-shifted version of the compressed audio signal when storing a decorrelated phase-invariable signal. The parameter processing unit is also configured to sum the phase-shifted version of the compressed audio signal and the decorrelated signal and obtain an expanded audio signal.
EFFECT: expanding a compressed audio signal into an expanded audio signal.
