ADAPTIVE GENERATION OF SCATTERED SIGNAL IN UPMIXER Russian patent published in 2018 - IPC H04S7/00 

FIELD: physics.

SUBSTANCE: upmixer can be configured to detect cases of transient states of the audio signal. In the cases of transient states of the audio signal, the upmixer can be configured to add signal-adaptive control to the expansion process of the scattered signal, in which M audio signals are output. The upmixer can change the expansion process of the scattered signal over time in such a way that in cases of transient states of the audio signal, the scattered parts of the audio signals can be distributed mainly only to the output channels spatially close to the input channels. In cases of intransitive states of the audio signal, the scattered parts of the audio signals can be distributed in a substantially uniform manner.

EFFECT: possibility of dividing the scattered and non-scattered parts of N input audio signals.
