Abstract
Some disclosed methods involve: receiving multi-channel audio data including unlabeled multi-channel audio data; extracting audio feature data from the unlabeled multi-channel audio data; applying a spatial masking process to a portion of the audio feature data; applying a contextual encoding process to the masked audio feature data, to produce predicted spatial embeddings in a latent space; obtaining reference spatial embeddings in the latent space; determining a loss function gradient based, at least in part, on a variance between the predicted spatial embeddings and the reference spatial embeddings; and updating the contextual encoding process according to the loss function gradient until one or more convergence metrics are attained.
