Abstract: A method includes obtaining an acoustic model of an environment. The acoustic model indicates a set of one or more acoustical properties of the environment. The method includes determining a placement location for a microphone within the environment based on the set of one or more acoustical properties of the environment and a pickup pattern of the microphone. The method includes displaying, on the display, a representation of the environment and a visual indicator that is overlaid onto the representation of the environment in order to indicate the placement location for the microphone.

Abstract: In one implementation, a method of playing audio is performed by a device located in a physical environment, coupled to two or more speakers, and including one or more processors and non-transitory memory. The method includes executing an operating system and an application. The method includes receiving, by the operating system from the application via an application programming interface, audio session parameters including a spatial experience value providing instructions for the spatial playback of audio associated with the application. The method includes receiving, by the operating system from the application, instructions to play audio data. The method includes adjusting, by the operating system, the audio data based on the spatial experience value. The method includes sending, by the operating system to the two or more speakers, the adjusted audio data.

Abstract: A method may include determining a location of a user, determining a virtual playback format based on the location of the user, where the virtual playback format includes a position of a virtual speaker that is fixed in an environment of the user, and determining an acoustic model based on the location of the user. The method also includes rendering audio at the playback device based on the acoustic model and the virtual playback format.

Abstract: In one implementation, a method of visualizing a combined audio pick-up pattern is performed at a first device in a physical environment, the first device including a display, one or more processors, and non-transitory memory. The method includes determining a first audio pick-up pattern of the first device. The method includes determining one or more second audio pick-up patterns of a respective one or more second devices. The method includes determining a combined audio pick-up pattern of the first device and the one or more second devices based on the first audio pick-up pattern and the one or more second audio pick-up patterns. The method includes displaying, on the display, a representation of the combined audio pick-up pattern.
In one implementation, a method of determining an audio emission pattern is performed at a first device at a first location, the first device having a microphone, one or more processors, and non-transitory memory. The method includes obtaining, via the microphone, first audio of a sound source. The method includes receiving, from one or more second devices, one or more second audio of the sound source. The method includes determining one or more second locations of the one or more second devices. The method includes determining an audio emission pattern of the sound source based on the first audio data, the one or more second audio data, and the one or more second locations, wherein the audio emission pattern of the sound source indicates a sound level at various locations relative to the sound source.-

Abstract: A method for self-calibrating a sound pickup process that uses a microphone array in a wearable device that also includes a loudspeaker, where the microphone array being in a physical arrangement with respect to the loudspeaker. The method obtains, for each of several microphones of the microphone array, one or more transfer functions that each represent a response of the microphone to sound from a position in an acoustic space. The method determines whether a physical arrangement of the microphone array with respect to the loudspeaker has changed and adjusts the transfer function, for at least one of the microphones of the several microphones, in response to determining that the current physical arrangement of the microphone array with respect to the loudspeaker has changed.

Abstract: Various implementations disclosed herein include devices, systems, and methods that that modify audio of played back AV content based on context in accordance with some implementations. In some implementations audio-visual content of a physical environment is obtained, and the audio-visual content includes visual content and audio content that includes a plurality of audio portions corresponding to the visual content. In some implementations, a context for presenting the audio-visual content is determined, and a temporal relationship between one or more audio portions of the plurality of audio portions and the visual content is determined based on the context. Then, synthesized audio-visual content is presented based on the temporal relationship.

Abstract: A machine learning model can determine output frequency response at different directions relative to a target audio output format, based on input including frequency response at directions relative to microphones of a capture device. A spatial filter determined based on the output frequency responses is applied to one or more of the microphone signals to map the spatial information from the microphone signals to the target audio output.

Abstract: Spatial filters are generated that map response of an audio capture device to head related transfer functions (HRTFs) for different positions of the audio capture device relative to the HRTFs. A current set of spatial filters are determined based on the plurality of spatial filters and a head position of a user. The microphone signals are convolved with the current set of spatial filters, resulting in a left audio channel and right audio channel that form output binaural audio channels. The binaural audio channels can be used to drive speakers of a headphone set to generate sound that is perceived to have a spatial quality. Other aspects are described and claimed.
