Abstract:
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.
Abstract:
An apparatus comprising means for: causing display of at least one world-locked volumetric object having at least one non-viewable region; determining a change in a user's viewing position relative to the at least one world-locked volumetric object; determining if the change in the user's viewing position relative to the at least one world-locked volumetric object will cause display of at least a portion of the at least one non-viewable region of the at least one world-locked volumetric object; and if it is determined that the change in the user's viewing position will cause display of at least a portion of the at least one non-viewable region, cause the at least one world-locked volumetric object to be user-locked.
Abstract:
A first input and a second input are received from a front camera and a rear camera respectively of a user device The first input is a video of a first object having a first orientation with respect to the front camera, the second input is a video of a second object having a second orientation with respect to the rear camera. A video output is generated including a first part based on the first input and a second part based on the second input. The video output is presented relative to a viewpoint of a first viewer, such that, at the viewpoint, the first and second parts of the video output are visible at the same time and the first object in the first part of the video output is orientated towards the second object in the second part of the video output.

Abstract:
In an example embodiment, method, apparatus and computer program product are provided. The method includes capturing an acoustic signal by a microphone of an apparatus to generate an electrical output signal. The acoustic signal is rendered in response to a source audio signal by a speaker through at least one speaker interface element of the apparatus. The electrical output signal is compared to the source audio signal in order to determine whether the electrical output signal is being affected by mechanical vibrations caused at least partially by the speaker interface element being at least partially interfered by a user. A predetermined action is further performed in the apparatus whenever it is determined that the electrical output signal is affected by the mechanical vibrations caused at least partially by the speaker interface element being at least partially interfered by the user.
Abstract:
In an example embodiment, a method, apparatus and computer program product are provided. The method includes determining one or more operating conditions of a device. A selection of a mode of operation of the device from at least a first mode and a second mode is facilitated based on the one or more operating conditions of the device. In the first mode, the device is configured to detect an operation input received from an audio source based on two or more audio sensors of the device. In the second mode, the device is configured to detect the operation input based on at least one of the two or more audio sensors and at least one non-audio sensor of the device.
Abstract:
The invention relates to a method, comprising receiving a first audio signal during an application execution in an apparatus, determining a volume level of a volume control interface for controlling a volume level of the first audio signal, controlling processing the first audio signal by at least one digital signal processing algorithm determined on the basis of the determined volume level of the volume control interface for controlling the volume level of the first audio signal, and outputting the controlled processed first audio signal at the determined volume level of the volume control interface. The invention further relates to an apparatus and a computer program product that perform the method.
