To implement some methods of attenuating noise it can be useful to obtain an accurate estimate of the noise in the microphone signals. Examples of the disclosure provide a method of accurately estimating incoherent noise levels. In examples of the disclosure a primary estimation of a noise amount is made. The primary estimation of a noise amount is used to determine a direction parameter and a diffuseness parameter. The determined direction parameter and the estimated diffuseness parameter are used to estimate a predicted level difference between a first microphone signal and a second microphone signal. A level difference between the first microphone signal and the second microphone signal is determined and a noise level is estimated using at least the determined level difference and the predicted level difference.

Estimating noise levels

An apparatus for assisting spatial audio signal processing, the apparatus including circuitry configured to: capture, at least using at least three microphones in the apparatus, sensor data including microphone audio signals; analyse the sensor data to determine at least one three-dimension direction of a sound source; and process the sensor data to map the at least one three-dimension direction of the sound source to at least one further direction, wherein the processing of the sensor data is configured to employ at least a parasagittal plane based mapping.

Apparatus for mapping sound source direction

Example embodiments are disclosed relating to virtual content. Example embodiments may involve providing video data for output to a user device, the video data representing a virtual scene comprising one or more virtual objects at respective locations in the virtual scene with which a user of the user device may interact during an interactive session. The interactive session may be paused and a resumption input may be received at a second time, subsequent to the first time, for unpausing the interactive session. Responsive to receiving the resumption input, it may be detected that interaction with a particular virtual object, with which the user has interacted prior to the interactive session being paused, is restricted due to physical properties of a real-world space in which the user is located at the second time. The virtual scene may be modified to permit interaction with the particular virtual object without the detected restriction.

Virtual content

An apparatus, method and computer-program is described relating to user control in augmented reality (AR). For example, the method may comprise determining, based on motion of a user, one or more future step locations along a path. The method may also comprise displaying, via an augmented reality display device associated with the user, one or more interactive items. Each of the one or more interactive items may be associated with a respective one of the future step locations and is displayed so as to be perceived at a respective display position which is at or near said associated respective future step location. The method may also comprise detecting a control input associated with a particular interactive item, based at least in part on the user having reached a selection area which is at or near said associated future step location along the path.

User control in augmented reality

An apparatus, method and computer program product for: providing spatial audio content for output via at least one loudspeaker, determining a position of at least one audio device operatively connected to the at least one loudspeaker, providing, in response to determining that the position of the at least one audio device corresponds to an audio zone associated with additional spatial audio content, the additional spatial audio content for output via the at least one audio device, receiving an instruction to include the additional spatial audio content in the spatial audio content, and supplementing, in response to receiving the instruction to include the additional spatial content in the spatial audio content, the spatial audio content with the additional spatial audio such that the additional spatial audio content is provided for output independent of the audio zone.

Supplementing content

An apparatus comprising means configured to:

Tactile audio display

An apparatus comprising means for: providing a user interface for enabling a user to select audio content, comprising an arrangement of multiple user-selectable visual elements at positions in the user interface that are indicative of different orientations from a user and have an appearance dependent upon audio content for the respective orientations; and responding to selection of a user-selectable visual element at a position in the user interface indicative of an orientation from the user to select, for processing, audio content for the orientation.

An apparatus, method and computer program is described for rendering visual content on a display screen. The apparatus comprises a means for rendering visual content on a display screen. The means for rendering is configured to render said visual content at a first rendering position on said display screen. The apparatus further comprises a means for detecting a user gaze direction through an eye correction means towards said first rendering position. The apparatus further comprises a means for receiving data relating to optical properties of said eye correction means at said detected user gaze direction. The apparatus further comprises a means for determining if said optical properties at said detected gaze direction provide a threshold level of suitability for viewing said visual content.
