Provided is a vibration presentation system that improves the convenience of a user in sensing vibrations at various body sites, or of a plurality of users in sensing vibrations. A vibration presentation system for presenting vibration signals for perception by tactile sense for media content, the vibration presentation system including: a vibrating body configured to generate vibrations corresponding to the vibration signals of a plurality of channels respectively; and a presentation target batch selection user interface including a plurality of (M, where M is an integer of 2 or more) combinations each of which contains one selection button and designation of a predefined body site for a channel included in the plurality of channels, wherein the vibrating body generates vibrations corresponding to the vibration signals for a body site for a channel included in a combination corresponding to a selection button selected from among M selection buttons.

An audio processing method includes: M first audio signals are obtained by processing a to-be-processed audio signal by M first virtual speakers; N second audio signals are obtained by processing the to-be-processed audio signal by N second virtual speakers; M first head-related transfer functions (HRTFs) centered at a left ear position and N second HRTFs centered at a right ear position are obtained; a first target audio signal is obtained based on the M first audio signals and the M first HRTFs; and a second target audio signal is obtained based on the N second audio signals and the N second HRTFs.

A sound generation system and related method include a user interface device and a processing device to obtain a specification of a three-dimensional space, obtain one or more sound tracks each comprising a corresponding sound signal associated with a corresponding sound source, present, in a user interface, representations representing one or more listeners and the one or more sound sources corresponding to the one or more sound signals in the three-dimensional space, responsive to a configuration of the locations of the one or more listeners or the locations of the one or more sound sources in the three-dimensional space in the user interface, determine filters based on the configuration and pre-determined locations of one or more loudspeakers, and apply the filters to the one or more sound signals to generate filtered sound signals for driving the one or more loudspeakers.

Playback of an audio signal is simulated from a playback position to a listening position. The simulation is performed with respect to a model of a listening area. The resulting loudness of the audio, perceived at the listening position, is rendered to a display. Other aspects are described and claimed.

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.

In some embodiments, a method comprises receiving audio content comprising left input channel signals and right input channel signals, and generating first and second input signals from the left and right input channel signals. The first input signal is based on a sum of the left and right input channel signals, and the second input signal is based on a difference of the left and right input channel signals. An array transfer function is applied to the first and second input signals to produced audio output signals, which can be provided to a plurality of audio transducers on one or more playback devices.

In one example in accordance with the present disclosure, a system is described. The system includes a decompose device to decompose a multi-channel audio stream into at least a first portion and a second portion. A synthesis device of the system independently synthesizes harmonics in each of the first portion and the second portion using different harmonic models. An audio generator of the system combines synthesized harmonics from the first portion and the second portion with the multi-channel audio stream to generate a synthesized audio output.

Immersive experiences for users are described herein. In an example, audio data from a plurality of audio sensors associated with a vehicle can be received by an audio data processing system. The audio data processing system can combine individual captured audio channels (e.g., from the plurality of audio sensors) into two or more audio channels for output via two or more speakers proximate a user. A first audio channel of the two or more audio channels can be output via a first speaker and second audio channel of the two or more audio channels to be output via a second speaker, wherein output of the first audio channel and the second audio channel causes a resulting sound corresponding to at least a portion of a sound scene associated with the vehicle. In an example, a user computing device operable by the user can receive an input from the user.

An online conversation management apparatus includes a processor. The processor acquires, across a network, reproduction environment information from at least one terminal that reproduces a sound image via a reproduction device. The reproduction environment information is information of a sound reproduction environment of the reproduction device. The processor acquires azimuth information. The azimuth information is information of a localization direction of the sound image with respect to a user of the terminal. The processor performs control for reproducing a sound image of each terminal based on the reproduction environment information and the azimuth information.

Electronic glasses track head movement of a user with respect to a location in empty space on top of a physical object. One or more processors process sound that externally localizes as binaural sound to the location in empty space on top of the physical object. Speakers in the electronic glasses provide the binaural sound to the user.
