摘要： A media system and a method of using the media system to reproduce spatial audio based on head-to-torso orientation, are described. The method includes determining a head-to-source orientation and a head-to-torso orientation based on head orientation data generated by a head tracking device. Determining the head-to-torso orientation includes determining torso movements based on movements of the head. The torso can be determined to move when the head movements meet a head movement condition, such as a predetermined angle of movement or pattern of movement. A binaural audio filter that is based on a head-related transfer function corresponding to both the head-to-source orientation and the head-to-torso orientation is applied to an audio input signal to generate an audio output signal. The audio output signal is played to accurately recreate spatial audio having sounds emitted to the user by a sound source. Other aspects are also described and claimed.

摘要： 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.

摘要： An audio system and a method of using the audio system to determine one or more of a head-related transfer function (HRTF) or a headphone equalization (HpEQ) filter for a user, are described. The audio system can determine an acoustic transfer function that relates an output signal detected by a microphone of a headphone worn by the user to an in input signal played by a speaker of the headphone. The acoustic transfer function corresponds to sound reflecting from a pinna of the user between the speaker and the microphone, and accordingly, the acoustic transfer function is user-specific. The user-specific acoustic transfer function can be used to determine the HRTF or the HpEQ filter for the user. Other aspects are also described and claimed.

摘要： Spatializing audio can include determining a draw-away curve of an audio signal and modifying the draw-away curve based on a strength of the audio signal. The strength can be determined prior to spatializing the audio signal. The audio signal can be attenuated or modified based on the modified draw-away curve. The attenuated or modified audio signal can be spatialized. Other aspects are described and claimed.

摘要： Audio processing for a headworn device can include obtaining ear geometry of a user. A frequency response or transfer function can be determined, based on the ear geometry of the user and a model of the headworn device, where the frequency response or transfer function characterizes an effect of a path between a speaker of the headworn device and an ear canal entrance of the user on sound. An equalization filter profile can be generated based on the based on the frequency response or transfer function. The equalization filter profile can be applied to an audio signal, and the audio signal can be used to drive the speaker of the headworn device.

摘要： 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.

摘要： A device and a method of using the device to determine a user-specific head-related transfer function (HRTF), are described. The device can determine first geometric data corresponding to visible features of a pinna of a user in an image, and second geometric data corresponding to hidden features of the pinna obfuscated by the visible features in the image. The first geometric data and the second geometric data are combined in a geometric model that describes a shape of the pinna, and the user-specific HRTF is determined based on the geometric model. The user-specific HRTF is used to render spatial audio to the user. Other aspects are also described and claimed.
