SYSTEM, METHOD, APPARATUS, AND COMPUTER-READABLE MEDIA FOR SPATIALLY SELECTIVE AUDIO AUGMENTATION

摘要

PROBLEM TO BE SOLVED: To provide a system, a method, an apparatus, and computer-readable media for processing a multichannel signal to produce an antinoise signal.SOLUTION: An apparatus of processing a multichannel signal includes means of performing an active noise cancellation operation on a first audio input channel. The apparatus also includes means of processing the multichannel signal to obtain a source component, and includes the step of performing a spatially selective processing operation on the multichannel signal to separate the source component from a background component. The apparatus further processes the obtained source component to produce a target component, and combines the antinoise signal and an augmented signal that is based on the target component to produce an audio output signal.
