Abstract
The audio processing system includes a memory to store a neural network trained to process an audio mixture to output estimation of at least a subset of a set of audio sources present in the audio mixture. The audio sources are subject to hierarchical constraints enforcing a parent-children hierarchy on the set of audio sources, such that a parent audio source in includes a mixture of its one or multiple children audio sources. The subset includes a parent audio source and at least one of its children audio sources. The system further comprises a processor to process a received input audio mixture using the neural network to estimate the subset of audio sources and their mutual relationships according to the parent-children hierarchy. The system further includes an output interface configured to render the extracted audio sources and their mutual relationships.
