Abstract: A method performed by a processor of a computer system including a headset that is to be worn on a head of a user. The method drives a speaker of the headset with an input audio signal to output sound into an environment. The method determines that the speaker is at least partially covered with a cupped hand. In response to determining that the speaker is at least partially covered with the cupped hand, applying a gain to the input audio signal to reduce an output sound level of the speaker.

Abstract: Audio processing with audio transparency can include receiving a user content audio signal and receiving a microphone signal. The microphone signal can contain sensed sound of a user environment. Strength of the sensed sound can be increased based on strength of the user content audio signal, to reduce a masking of the sensed sound during playback. The sensed sound and the user content audio signal can be combined in a composite output audio signal used to drive a speaker. Other aspects are also described and claimed.

Abstract: A method for routing audio content through an electronic device that is to be worn by a user. The method obtains a communication and determines whether the communication is private. In response to determining that the communication is private, the method drives a bone conduction transducer of the electronic device with an audio signal associated with the communication. In response to determining that the communication is not private, however, the method drives a speaker of the electronic device with the audio signal.

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: Processing of ambience and speech can include extracting from audio signals, ambience and speech signals. One or more spatial parameters can be generated that define spatial characteristics of ambience sound in the one or more ambience audio signals. The primary speech signal, the one or more ambience audio signals, and the spatial parameters can be encoded into one or more encoded data streams. Other aspects are described and claimed.

Abstract: Transfer functions can describe responses of microphones or ears to sounds at different locations on a sphere. The transfer functions can be compressed by determining, based on transfer functions, a) one or more basis transfer functions, and b) spherical harmonics coefficients that describe variations of the transfer functions with respect to spherical coordinates. Other aspects are described and claimed.

Abstract: Image analysis of a video signal is performed to produce first metadata, and audio analysis of a multi-channel sound track associated with the video signal is performed to produce second metadata. A number of time segments of the sound track are processed, wherein each time segment is processed by either (i) spatial filtering of the audio signals or (ii) spatial rendering of the audio signals, not both, wherein for each time segment a decision was made to select between the spatial filtering or the spatial rendering, in accordance with the first and second metadata. A mix of the processed sound track and the video signal is generated. Other embodiments are also described and claimed.

Abstract: 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.
