Audio signal decoding process, involves constructing uncorrelated signal from audio signals based on audio signal frequency transformation, and joining audio and uncorrelated signals to generate signal representing acoustic scene

摘要

The process involves transforming frequency of an audio signal to calculate a spectrum of received audio signal. An uncorrelated signal is constructed from the received audio signal based on the frequency transformation. The received audio signal and the uncorrelated signal are combined to generate a signal, which represents an acoustic scene. Independent claims are also included for the following: (a) a decoding device for an audio signal in the temporal field (b) a computer program with coded instructions to execute the decoding process of audio signal.
