Title: A METHOD AND AN APPARATUS FOR ENHANCING AN AUDIO SIGNAL CAPTURED IN AN INDOOR ENVIRONMENT
Abstract:
A first audio signal is received from a primary audio signal input. The first audio signal that is associated with a first importance designation indicator (IDI) that indicates an importance of the first audio signal with respect to one or more other audio signals in the indoor environment, wherein the first audio signal includes a primary audio signal that is to be enhanced. A second input indicative of a second audio signal is received from a secondary audio signal source. The second audio signal is associated with a second IDI indicating the importance of the second audio signal. A determination that the first audio signal includes the second audio signal is performed. A modification, based on the first IDI and the second IDI, of the first audio signal is performed to obtain a modified version of the first audio signal that enhances the primary audio signal.
