Sound Event Localization and Detection of Overlapping Sources Using Convolutional Recurrent Neural Networks
TLDR
The proposed convolutional recurrent neural network for joint sound event localization and detection (SELD) of multiple overlapping sound events in three-dimensional (3-D) space is generic and applicable to any array structures, robust to unseen DOA values, reverberation, and low SNR scenarios.
