Abstract
Disclosed is an apparatus and method for extracting a sound source from a multi-channel audio signal. A sound source extracting method includes transforming a multi-channel audio signal into two-dimensional (2D) data, extracting a plurality of feature maps by inputting the 2D data into a convolutional neural network (CNN) including at least one layer, and extracting a sound source from the multi-channel audio signal using the feature maps.
