  • Publication number: 20230379645
    Abstract: The technology generally relates to spatial audio communication between devices. For example, a first device and a second device may be connected via a communication link. The first device may capture audio signals in an environment through two or more microphones. The first device may encode the captured audio with spatial configuration data. The first device may transmit the encoded audio via the communication link to the second device. The second device may decode the encoded audio into binaural or ambisonic audio to be output by one or more speakers of the second device. The binaural or ambisonic audio may be converted into spatial audio to be output. The second device may output the binaural or spatial audio to create an immersive listening experience.

  • Patent number: 11751000
    Abstract: A method of modeling the human head is provided. The human head model has a width and an aspect ratio. The aspect ratio defines different head shapes independent of the size of the human head model. The method includes the steps of forming a high-frequency head model based on ray-tracing and a plurality of half plane sections, coupling the high-frequency head model with a far-field shadowing filter, coupling the far-field shadowing filter with a near-field compensation filter to compensate for acoustic changes between the far-field and near-field regions and modifying the aspect ratio of the human head model to configure variable geometric models of the human head ranging from a nearly spherical to a very narrow embodiment.
