Abstract: An apparatus may include an interface system and a first local control system. The first local control system may be configured to: receive first sensor data from a first preview environment while a content stream is being presented in the first preview environment; generate, based at least in part on the first sensor data, first user engagement data corresponding to one or more people in the first preview environment, the first user engagement data indicating estimated engagement with presented content of the content stream; output, via the interface system, either the first user engagement data, the first sensor data, or both, to a data aggregation device; and determine, based at least in part on user preference data, whether to provide at least some of the first user engagement data, at least some of the first sensor data, or both, to one or more machine learning (ML) models.

Abstract: Some implementations involve receiving location information for each of a plurality of audio devices in an audio environment, generating, based at least in part on the location information, rendering information for a plurality of audio devices in an audio environment and determining, based at least on part on the rendering information, a plurality of echo reference metrics. Each echo reference metric may correspond to audio data reproduced by one or more audio devices of the plurality of audio devices. The rendering information may include a matrix of loudspeaker activations. Some examples involve making, based at least in part on the echo reference metrics, an importance estimation for each of a plurality of echo references, selecting, based at least in part on the importance estimation, one or more echo references and providing them to at least one echo management system for canceling or suppressing echoes.
