Abstract: Sound sources can be spatially rendered in a setting and shown through a display. In response to satisfaction of a threshold criterion that is satisfied based on relative distance between the sound sources and a position of a listener, the rendering of the sound sources can be adjusted to maintain spatial integrity of the sound sources. The adjustment can be performed to prevent one of the sound sources from arriving at the listener earlier than another of the sound sources.

Abstract: A plurality of microphone signals of a microphone array may be obtained. An environment change may be detected based on the microphone signals. In response, a reverberation time environment may be determined. The reverberation may be used to modify a playback audio signal.

Abstract: Aspects of the subject technology relate to providing device-independent audio for electronic devices. In one or more implementations, microphone data captured by multiple microphones at an electronic device may be provided to a device-specific audio generalizer at the electronic device. The device-specific audio generalizer may utilize device specific information to generalize the microphone data to form device-independent audio data. The device-independent audio data may then be provided to a device-independent machine learning model at the electronic device or another electronic device for further processing.

Abstract: Aspects of the subject technology provide for joint processing of signals from acoustic microphones and signals from vibration sensors that directly or remotely sense vibrations of the source of the sound itself. The vibration sensors may include remote vibration sensors such as a light-based microphone, which may be implemented as an optical microphone. Joint processing of the signals may include detecting a sound from the source in the signals from the acoustic microphone by selecting a portion of the signals from the acoustic microphone based on the signals from the vibration sensor.
