Abstract: Some disclosed methods involve receiving audio data of at least a first audio data type and a second audio data type, including audio signals and associated spatial data indicating intended perceived spatial positions for the audio signals, determining at least a first feature type from the audio data and applying a positional encoding process to the audio data, to produce encoded audio data. The encoded audio data may include representations of at least the spatial data and the first feature type in first embedding vectors of an embedding dimension. Some methods may involve training a neural network, based on the encoded audio data, to transform audio data from an input audio data type having an input spatial data type to a transformed audio data type having a transformed spatial data type. Some methods may involve training a neural network to identify an input audio data type.

Abstract: Some disclosed methods involve receiving microphone signals from a microphone system, including signals corresponding to one or more sounds detected by the microphone system. Some methods may involve determining, via a trained neural network, a filtering scheme for the microphone signals, the filtering scheme including one or more filtering processes. The trained neural network may be configured to implement one or more subband-domain adaptive filter management modules. Some methods may involve applying the filtering scheme to the microphone signals, to produce enhanced microphone signals.
