A virtual meeting system is discussed herein. An online meeting application can provide a parallel virtual meeting between or among two or more participants of a main virtual meeting. The parallel virtual meeting permits two or more participants of the main virtual meeting to have a “smaller-sized” meeting in parallel with the main virtual speaker or presentation while still participating in the main virtual meeting. Therefore, the participants of the parallel virtual meeting do not have to connect via another device or application and can avoid disrupting the main virtual meeting. The parallel virtual meeting can permit two separate meetings, such as one meeting with all participants and one meeting with a subset of all the participants.

An information processing method receives settings of a plurality of pieces of information on a plurality of physical spaces that respectively correspond to a plurality of pieces of information on a plurality of logical spaces, receives a first group of a plurality of pieces of first acoustic image localization information that indicates a position of an acoustic image to be localized in each of the plurality of logical spaces using first coordinates in the plurality of logical spaces, receives a change in one piece of first acoustic image localization information, among the first group of the plurality of pieces of first acoustic image localization information, changes other pieces of first acoustic image localization information, among the first group of the plurality of pieces of first acoustic image localization, in response to the received change in the one piece of first acoustic image localization information, and transforms the first group of the plurality of pieces of first acoustic image localization information respectively into a plurality of pieces of second acoustic image localization information using second coordinates in the plurality of physical spaces.

In various embodiments, a communication application selectively modifies sounds associated with a selected location or entity in one or more images. In operation, the communication application receives an image of an environment of a first device and an audio signal associated with the environment. The communication application receives first user input selecting a location in the image, and modifies a first sound included in the audio signal based on the selected location in the image, where at least a portion of the audio signal is unmodified.

A transmission apparatus includes a first transmission unit that transmits sound data to a first sound channel in a transmission path, and a second transmission unit that transmits meta data related to the sound data to a second sound channel in the transmission path while ensuring synchronization with the sound data.

An apparatus, method and computer program for signaling change events at an audio output device are disclosed. The apparatus may include circuitry for detecting, during an audio communications session between a first user device and a second user device, a change event at a first earphones device associated with the first user device, the first earphones device included of first and second earphones. The apparatus may also include circuitry for signaling the detected change event to the second user device and/or a second audio output device associated with the second user device.

The present technology relates to a signal processing device, method, and program that can improve encoding efficiency.

A signal processing device includes: an acquisition unit that acquires reverb information including at least one of space reverb information specific to a space around an audio object or object reverb information specific to the audio object and an audio object signal of the audio object; and a reverb processing unit that generates a signal of a reverb component of the audio object on the basis of the reverb information and the audio object signal. The present technology can be applied to a signal processing device.

A method for processing an audio signal and an electronic device, relate to the field of audio and video technology. The method includes: detecting beat information of the audio signal; and obtaining virtual surround sound for the audio signal by performing a convolution operation on a head-related transfer function and the audio signal based on the beat information of the audio signal.

Aspects of the disclosure include methods, apparatuses, and non-transitory computer-readable storage mediums for decoding audio data of an audio scene. One apparatus includes processing circuitry that receives first audio source data and second audio source data. The first audio source data corresponds to a space of interest in the audio scene and the second audio source data does not correspond to the space of interest in the audio scene. The space of interest in the audio scene is represented by at least one of a listener space, an audio channel, or an audio object. The processing circuitry decodes the first audio source data based on the space of interest.

Processes, methods, systems, and devices are disclosed for synchronizing multiple wireless data streams captured in action by various sensors, with lost data recovery. For example, a source device may have multiple sensors acquiring data and sending the data streams (e.g., via Bluetooth connections) to a target device. Timing information may be appended for each of the data streams. Data packets of the multiple data streams may be formed with the timing information. The data packets may be transmitted to a target device that is configured to synchronize the multiple data streams using the timing information. The target device, applying the example processes or techniques of this disclosure, may accurately synchronize the multiple data streams. In some cases, the target device may capture additional data streams and the processor synchronizes all data streams of both the source and the target devices.

The present disclosure generally relates to interfaces and techniques for media playback on one or more devices. In accordance with some embodiments, an electronic device includes a display, one or more processors, and memory. The electronic device receives user input and, in response to receiving the user input, displays, on the display, a multi-device interface that includes: one or more indicators associated with a plurality of available playback devices that are connected to the device and available to initiate playback of media from the device, and a media playback status of the plurality of available playback devices.
