  • Patent number: 12294850
    Abstract: The present technology relates to an audio processing apparatus and method and a program that make it possible to obtain sound of higher quality. An acquisition unit acquires an audio signal and metadata of an object. A vector calculation unit calculates, based on a horizontal direction angle and a vertical direction angle included in the metadata of the object and indicative of an extent of a sound image, a spread vector indicative of a position in a region indicative of the extent of the sound image. A gain calculation unit calculates, based on the spread vector, a VBAP gain of the audio signal in regard to each speaker by VBAP. The present technology can be applied to an audio processing apparatus.

  • Patent number: 12212914
    Abstract: A headset presents audio sounds with first and second speakers disposed in first and second earcups that fit over first and second of an end user's ears. One ear cup adjusts with a greater travel distance relative to the other earcup so that the headset rests on the end user head with the one earcup raised above an ear and the other on an ear. A position sensor disposed in the headset detects the headset configuration to turn off audio at the speaker of the earcup that is displaced from the ear while increasing volume at the speaker of the earcup that remains over an ear. In addition, when only one ear is covered by an earcup, the audio presentation converts from stereo to monoaural.
