Abstract: In a device or method for rendering a sound program for headphones, a location is received for placing the sound program with respect to first and second ear pieces. If the location is between the first ear piece and the second ear piece, the sound program is filtered to produce low-frequency and high-frequency portions. The high-frequency portion is panned according to the location to produce first and second high-frequency signals. The low-frequency portion and the first high-frequency signal are combined to produce a first headphone driver signal to drive the first ear piece. A second headphone driver signal is similarly produced. The sound program may be a stereo sound program. The device or method may also provide for a location that is between the first ear piece and a near-field boundary. Other aspects are also described.

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: A microphone array included in a portable electronic device is used to generate various virtual studio microphones by combining one or more microphone signals to produce one or more acoustic pickup beams. An error is determined in a position of the microphone array relative to an audio source to be recorded. An interface is displayed to instruct a user on repositioning the microphone array relative to the instrument and the instrument is recorded using the repositioned microphone array.

Abstract: 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.

Abstract: An audio output device case that includes one or more input devices and a display component, and is communication with at least one or more audio output devices and an audio source, performs a method that includes displaying information corresponding to a functionality associated with outputting audio at the one or more audio output devices. While displaying the information, the audio output device case receives, via the one or more input devices, an input, and in response to receiving the input communicates instructions for outputting, via the one or more audio output devices, audio associated with the functionality.

Abstract: A binaural sound reproduction system, and methods of using the binaural sound reproduction system to dynamically re-center a frame of reference for a virtual sound source, are described. The binaural sound reproduction system may include a reference device, e.g., a mobile device, having a reference sensor to provide reference orientation data corresponding to a direction of the reference device, and a head-mounted device, e.g., headphones, having a device sensor to provide device orientation data corresponding to a direction of the head-mounted device. The system may use the reference orientation data to determine whether the head-mounted device is being used in a static or dynamic use case, and may adjust an audio output to render the virtual sound source in an adjusted source direction based on the determined use case. Other embodiments are also described and claimed.

Abstract: 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.
