  • Patent number: 11081097
    Abstract: A system and method for passively balancing electroacoustic transducers so that sounds other than the transducer's output can be detected. A transducer producing audio output based upon an input audio signal can operate in reverse to produce a signal in response to the impact of external sound upon the transducer from another source. This “reverse” or “microphone” signal represents the sound from the other source. Transducers are operated in monophonic mode, each in opposite polarity to the other thus canceling out and leaving only the microphone signal created by the transducers, i.e., a signal representing the external sound. The microphone signal can be amplified, and can be filtered and processed to identify and/or obtain various types of information about the sound received by the transducers.

  • Patent number: 11082796
    Abstract: An exemplary acoustics generation system accesses acoustic propagation data representative of characteristics affecting propagation of a virtual sound to an avatar within an extended reality world being experienced by a user associated with the avatar. Based on the acoustic propagation data, the acoustics generation system also generates a binaural audio signal representative of the virtual sound as experienced by the avatar when the propagation of the virtual sound to the avatar is simulated in accordance with the characteristics affecting the propagation. Additionally, the acoustics generation system prepares the binaural audio signal for presentation to the user as the user experiences the extended reality world by way of the avatar. Corresponding methods and systems are also disclosed.

  • Patent number: 10998870
    Abstract: There is provided an information processing apparatus, an information processing method, and a program that enable output of a sound to be heard at an assumed viewing/listening position of a zoom image when an image is displayed as the zoom image. In the case of image content such as a sports broadcast, the individual location information, direction and posture information, and audio data of each player as an object are stored separately for direct sound and reverberant sound, at the time of recording. At the time of reproducing a zoom image, the direct sound and the reverberant sound are mixed according to the direction of a player as an object with respect to an assumed viewing/listening position in the zoom image, so that a sound to be heard at the assumed viewing/listening position is output. The present disclosure can be applied to a content reproduction apparatus.

  • Patent number: 10966043
    Abstract: Embodiments relate to calibrating head-related transfer functions (HRTFs) for a user of an audio system (e.g., as a component of a headset) using cartilage conducted sounds. A test sound is presented to a user using a transducer (e.g., cartilage conduction) and an audio signal is responsively received via a microphone at an entrance to the user's ear canal. The test sound and audio signal combination may be provided to an audio server where a model is used to determine one or more HRTFs for the user. Information describing the one or more HRTFs is provided to the audio system to be used for providing audio to the user. The audio server may also use a model to determine geometric information describing a pinna of the user based on the combination. In one embodiment, the geometric information is used to determine the one or more HRTFs for the user.
