Implementations of the disclosed subject matter provide a method of transmitting, from a mobile robot device, sound and/or at least one image captured by a sensor to a remote user device. The mobile robot device may receive at least one first control operation for the mobile robot device to move within an area via a communications network from a remote user device. An audio signal may be transmitted based on sound received at a microphone of the mobile robot device in the area. The audio signal received from the remote user device may be output at a speaker of the mobile robot device. A volume of the audio signal output by the speaker may be adjusted based on a size of the area and on an average or a median of an amplitude of frequencies in the area based on the sound received by the microphone.

An apparatus for positioning at least part of a sound field based on a target direction, the apparatus comprising means configured to: obtain at least one audio signal; obtain speaker setup information; obtain, for at least two processing paths, at least one processing path parameter, the at least one processing path parameter comprising a target direction associated with each of the at least two processing paths; process, for each of the at least two processing paths, the at least one audio signal based on the at least one processing path parameter to generate a multiple-channel audio signal, wherein for each processing path the means is configured to: generate at least two at least partly mutually incoherent audio signals from the at least one audio signal; determine at least two panning gains based on the target direction associated with the processing path and the speaker setup information; apply each of the at least two panning gains with an associated one of the at least partly mutually incoherent audio signal to generate at least two panning gain applied at least partly mutually incoherent audio signals; and combine the at least two panning gain applied at least partly mutually incoherent audio signals to generate the multiple-channel audio signal; and combine the multiple-channel audio signal from each processing path to generate a combined panning gain applied multiple-channel audio signal.

An attention-based audio adjustment method includes identifying, at a processor and at a first time, a first estimated gaze direction of a first participant within a virtual environment. First audio data is received at the processor from a compute device of the first participant. A second estimated gaze direction of the first participant within the virtual environment is determined by the processor at a second time. Second audio data, different from the first audio data and associated with a virtual representation of a second participant and/or a virtual object, is automatically generated by the processor, based on the first audio data and the second estimated gaze direction. A signal is sent from the processor to the compute device of the first participant, at a third time, to cause an adjustment to an audio output of the compute device of the first participant based on the second audio data.

An apparatus, method and computer program is disclosed. The apparatus may comprise means for providing first virtual content for presentation, which first virtual content is associated with a first space and comprises one or more first virtual objects. One of the first virtual objects may comprise one or more virtual objects having respective audio signals and another may represent a miniature representation of a second space into which the user can transition. The miniature representation may have a second scale, smaller or larger than the first scale, and may comprise one or more second virtual objects having respective audio signals audible from outside of the second space. The apparatus may further comprise means for determining whether at least part of the user is within the first space or the second space, and dependent on the determination, modifying the audio signal of one or more of the first or second virtual objects.

Systems and methods are provided for using one or more external Bluetooth speakers in conjunction with an in-vehicle Bluetooth-enabled audio system. Locational features or aspects of the external Bluetooth speakers and the in-vehicle Bluetooth-enabled audio system can be leveraged in a manner that allows for automatic or manual adjustment of the one or more external Bluetooth speakers, e.g., adjusting left/right balance of the one or more external Bluetooth speakers based on the position or location of the or more external speakers relative to the vehicle, in-vehicle Bluetooth-enabled audio system, etc.

An audio system and method of spatially rendering audio signals that uses modified virtual speaker panning is disclosed. The audio system may include a fixed number F of virtual speakers, and the modified virtual speaker panning may dynamically select and use a subset P of the fixed virtual speakers. The subset P of virtual speakers may be selected using a low energy speaker detection and culling method, a source geometry-based culling method, or both. One or more processing blocks in the decoder/virtualizer may be bypassed based on the energy level of the associated audio signal or the location of the sound source relative to the user/listener, respectively. In some embodiments, a virtual speaker that is designated as an active virtual speaker at a first time, may also be designated as an active virtual speaker at a second time to ensure the processing completes.

An apparatus including circuitry configured to: obtain at least two audio signals; determine, with respect to the at least two audio signals, an audio object part and an ambience audio part; determine a level parameter based on the ambience audio part; apply a noise suppression to the audio object part, wherein the noise suppression is configured to be controlled based on the determined level parameter; and generate a noise suppressed audio object part based on the applied noise suppression.

An example method includes, based on an adjustment to a first displayed volume control, instructing the first playback device to adjust playback volume level; based on an adjustment to a second displayed volume control, instructing the second playback device to adjust playback volume level; after sending the commands, instructing the first and/or second playback device to process an audio stream into a first and/or second channel and to reproduce a respective one of the first and second channel, wherein the grouped first and second playback devices provide multi-channel sound; and based on an adjustment to a third displayed volume control, instructing the first and/or second playback device to adjust a group volume level for both the first and second playback devices.

A method of sound box position adjustment is provided, including: An electronic device sends a first playing instruction to a sound box, where the first playing instruction is used to instruct the sound box to rotate from a first position to a second position in a preset direction and play positioning audio in a process of rotation, and a loudness of the positioning audio is unchanged when the positioning audio is being played; the electronic device receives the positioning audio; the electronic device determines indication information based on the positioning audio, where the indication information is used to determine a target position of the sound box, the target position is a position of the sound box when a loudness of the received audio is largest in a process of receiving the positioning audio; and the electronic device sends the indication information to the sound box.
