An audio system and a method of determining an audio filter based on a position of an audio device of the audio system, are described. The audio system receives an image of the audio device being worn by a user and determines, based on the image and a known geometric relationship between a datum on the audio device and an electroacoustic transducer of the audio device, a relative position between the electroacoustic transducer and an anatomical feature of the user. The audio filter is determined based on the relative position. The audio filter can be applied to an audio input signal to render spatialized sound to the user through the electroacoustic transducer, or the audio filter can be applied to a microphone input signal to capture speech of the user by the electroacoustic transducer. Other aspects are also described and claimed.

Audio system and method of determining audio filter based on device position

An output device that includes a housing, a first speaker driver that is integrated within the housing at a first location and is arranged to project sound into an ambient environment in a first direction, and a second speaker driver that is integrated within the housing at a second location that is different than the first location and is arranged to project sound into the ambient environment, where the first and second speaker drivers are integrated within the housing and share a common back volume within the housing.

Dual-speaker system

A method performed by a programmed processor of an audio system, the method includes retrieving a head-related transfer function (HRTF) dataset from memory, processing the HRTF dataset to remote comb filtering effects during audio playback; applying, to each HRTF in the processed HRTF dataset, a gain to increase a magnitude of the HRTF at a frequency range; and storing the processed HRTF dataset in memory.

Method and system for processing head-related transfer functions

In one implementation, a method of playing audio data is performed at a device including a frame configured for insertion into an outer ear, a speaker coupled to the frame, an image sensor coupled to the frame, one or more processors, and non-transitory memory. The method includes capturing, using the image sensor, one or more images of a physical environment. The method includes generating audio data based on the one or more images of the physical environment. The method includes playing, via the speaker, the audio data.

Device with speaker and image sensor

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.

Self-calibrating microphone and loudspeaker arrays for wearable audio devices

A multimedia device having a housing that includes a display screen, two tweeters, two mid-range drivers, and two woofers, which are integrated into the housing. Both woofers are disposed at a first distance from a center vertical axis of the housing in opposite horizontal directions, both tweeters are disposed at a second distance from the center vertical axis in the opposite horizontal directions, and both mid-range drivers are disposed at a third distance from the center vertical axis in opposite horizontal directions. In addition, both the first and second distances are greater than the third distance.

Speaker driver arrangement for implementing cross-talk cancellation

A computer system outputs audio content via one or more audio output devices. If the audio content includes information that enables spatialization of the audio content, the system outputs the audio content in a simulated three-dimensional environment, including, if the audio content corresponds to a first category of content, causing the one or more audio output devices to simulate production of the audio content in a first virtual space, and if the audio content corresponds to a second category of content, causing the one or more audio output devices to simulate production of the audio content in a second virtual space that has different simulated acoustic properties than simulated acoustic properties of the first virtual space.

Systems, methods, and graphical user interfaces for using spatialized audio during communication sessions

Loudspeakers are described that may reduce comb filtering effects perceived by a listener by either 1) moving transducers closer to a sound reflective surface (e.g., a baseplate, a tabletop or a floor) through vertical (height) or rotational adjustments of the transducers or 2) guiding sound produced by the transducers to be released into the listening area proximate to the reflective surface through the use of horns and openings that are at a prescribed distance from the reflective surface. The reduction of this distance between the reflective surface and the point at which sound emitted by the transducers is released into the listening area may lead to shorter reflected path that reduces comb filtering effects caused by reflected sounds that are delayed relative to the direct sound. Accordingly, the loudspeakers shown and described may be placed on reflective surfaces without severe audio coloration caused by reflected sounds.

Loudspeaker with reduced audio coloration caused by reflections from a surface

A method performed a local device that is communicatively coupled with several remote devices, the method includes: receiving, from each remote device with which the local device is engaged in a communication session, an input audio stream; receiving, for each remote device, a set parameters; determining, for each input audio stream, whether the input audio stream is to be 1) rendered individually or 2) rendered as a mix of input audio streams based on the set of parameters; for each input audio stream that is determined to be rendered individually, spatially rendering the input audio stream as an individual virtual sound source that contains only that input audio stream; and for input audio streams that are determined to be rendered as the mix of input audio streams, spatially rendering the mix of input audio streams as a single virtual sound source that contains the mix of input audio streams.

Spatial audio controller

Disclosed are systems and methods for automatically transitioning between communication modes of wearable audio output devices based solely on acoustic analysis. The audio output devices may operate in one of three electroacoustic modes. In the transparency mode, an audio output device may pass through the speech signal of a nearby user. In the peer-to-peer mode, the audio output device may establish a direct low-latency radio frequency (RF) link to another audio output device. In the telephony mode, the audio output device may communicate with another audio output device using networked telephony. The disclosed methods and systems perform acoustic analysis of the near-field speech signal of a local wearer of the audio output device and the far-field speech signal of a remote talker to determine the best mode for the audio output device to use and to seamlessly transition between the modes as the acoustic environment between the wearers changes.

Automatic acoustic handoff

Virtualizing speakers for a headphone set can include determining a location of a display. Locations of one or more virtual speakers can be assigned based on the location of the display. A first virtual speaker can be located at the display. A position of a head of a user can be tracked. Audio content can be spatialized with a spatial renderer to generate spatialized audio signals, based on the tracked position of the head and the locations of the virtual speakers. Other aspects are also described and claimed.

Placement of virtual speakers based on room layout

Spatial management of audio

The present disclosure generally relates techniques for audio-assisted enrollment of biometric features. In some embodiments, methods and devices for assisting users with enrollment of biometric features, using spatial audio cues, are described.

Audio assisted enrollment

A system for enhancing audio including a plurality of sensors, an output device, and a processor in communication with the plurality of sensors and the output device. The processor is configured to process data captured by the plurality of sensors, and based on that, modify an output of the output device. The processor also is configured to determine whether there are a plurality of users associated with a video conferencing session, determine which user of the plurality of users is speaking, and enhance the audio or video output of the speaking user on the output device.

Devices with enhanced audio

Disclosed are techniques for a multimedia device with audio and video capturing capability to identify an audio device based on acoustic playback signal if the audio device cannot be identified from captured video. The multimedia device may assemble a list of candidate audio devices that are a possible match for the observed audio device from a database of previously recognized audio devices and may transmit commands to the candidate audio devices to play acoustic identification signals. The acoustic identification signals may be audible sound or ultrasonic tone sequences with embedded identification information unique to each audio device. The multimedia device may record and analyze the acoustic identification signals received from any of the candidate audio devices to construct metrics to select the most likely candidate for the observed audio device. The metrics may include time of flight, direction of arrival, received amplitude, direct-to-reverberant ratio (DRR) of the acoustic identification signals.
