Abstract: Disclosed herein are example techniques to facilitate calibrating a portable playback device. An example implementation involves determining that a playback device is to perform an equalization calibration of the playback device and initiating the equalization calibration. Initiating the equalization calibration involves (i) outputting audio content, (ii) capturing audio data representing reflections of the audio content within an area in which the playback device is located, (iii) determining an acoustic response of the area in which the playback device is located, (iv) selecting a stored acoustic response from the acoustic response database that is most similar to the determined acoustic response of the area in which the playback device is located, and (v) applying to the audio content, via the playback device, a set of stored audio calibration settings associated with the selected stored acoustic area response.

Abstract: An iterative method for finding which user characteristic data should be used for pruning a database of available HRTFs before selecting an HRTF from the database for a target user (target listener.) The selected HRTF is expected to be the one that is more suitable for target user. This is also referred to as having “personalized” the HRTF selection process for the target user. This is not about computing a suitable HRTF but rather how to use the user characteristic data to improve the chances of selecting the most appropriate one from a database of available HRTFs. Other aspects are also described and claimed.

Abstract: Examples are disclosed relating to providing spatialized audio to multiple users. In one example, a computing device presents spatialized audio to multiple users within an environment via communicative connection to one or more wearable spatial audio output devices. For each communicatively connected wearable spatial audio output device, a user-specific subset of audio tracks is generated from a set of audio tracks for a dynamic audio object positioned within the environment based on one or more user-specific parameters. A location of the wearable spatial audio output device is determined relative to the dynamic audio object, and based upon this location, a device-specific spatialized audio mix is generated that includes the user-specific subset of audio tracks. The device-specific spatialized audio mixes are sent to the wearable spatial output devices, and playback of the device-specific spatialized audio mixes are synchronously initiated at each wearable spatial audio output device.

Abstract: A wearable simulation system worn by a user outputs optical and acoustic signals that cause the user to perceive a simulation. The simulation may be an immersive virtual world or, alternatively, an augmentation to the real world. The wearable simulation system also captures acoustic and optical signals from the environment around the user and then selectively incorporates these signals into the simulation. Accordingly, the user may perceive the environment to a limited extent, while still remaining engaged with the simulation. At least one advantage of the disclosed techniques is that the wearable simulation system does not completely interfere with user perception of the environment, thereby reducing the risk of the user missing important real-world events or being otherwise unaware of such real-world events.

Abstract: A sound processing apparatus includes a signal processing device that individually performs first localization setting (e.g., sound volume panning) for setting localization of an input sound signal based on a value of a first parameter and second localization setting (e.g., delay panning) for setting localization of the input sound signal based on a value of a second parameter. In response to an adjustment by an operation device of the value of one of the first and second parameters, a control device automatically changes the value of the other of the first and second parameters. In this way, sound image localization based on the first localization setting and sound image localization based on the second localization setting are automatically controlled in an interlocked relation to each other. At least one of the sound signals localized based on the first and/or second localization setting is output to an output destination.
