An apparatus for generating a 3D presentation is described wherein the 3D presentation (that could include a 3D movie, a VR (virtual reality) and/or an AR (augmented reality) content) from original 3D content including original audio and visual components, forming a plurality of scenes, each scene being associated with a respective environment or environments having respective audio characteristics. The original audio components in at least some of the scenes are modified by the apparatus to conform with or compensate for the acoustic characteristics of the respective scene and/or the environment of the location where the presentation is taking place.

An audio appliance includes an oscillatable diaphragm, a first heat-dissipation unit, a second heat-dissipation unit, and a control unit. The first heat-dissipation unit dissipates heat at a first rate and the second heat-dissipation unit dissipates heat at a second rate. The control unit can receive an indication of a temperature of the first heat-dissipation unit and an indication of a temperature of the second heat-dissipation unit. The control unit provides oscillation control of the oscillatable diaphragm to maintain the temperature of the first heat-dissipation unit below a first threshold and/or to maintain the temperature of the second heat-dissipation unit below a second threshold. The control unit can provide the oscillation control responsive to each of the indication of the temperature of the first heat-dissipation unit and the indication of the temperature of the second heat-dissipation unit exceeding a respective threshold.

An aspect of some embodiments of the present invention relates to a system for processing audiovisual data. The system is configured to mediate between a user and an audio post-processing system, to enable the user to easily assign sounds to corresponding objects in a scene and for selecting suitable sounds effects to be applied to desired sounds by the post-processing system. Optionally, the sounds effects are selected according to distances between the objects and the camera and/or distances between objects in the scene with other objects which may or may not be in the scene.

An apparatus generating audio cues for content indicative of the position of audio objects within the content comprising: an audio processor receiving raw audio tracks for said content and information indicative of the positions of at least some of said audio tracks within frames of said content, said audio processor generating corresponding audio parameters; an authoring tool receiving said audio parameters and generating encoding coefficients, said audio parameters including audio cue of the position of audio objects corresponding to said tracks in at least one spatial dimension; and a first audio/video encoder receiving an input and encoding said input into an audio visual content having visual objects and audio objects, said audio objects being disposed at location corresponding to said one spatial position, said encoder using said encoding coefficients for said encoding.

Improved techniques for presenting sound effects at a portable media device are disclosed. The sound effects can be output as audio sounds to an internal speaker, an external speaker, or both. In addition, the audio sounds for the sound effects can be output together with other audio sounds pertaining to media assets (e.g., audio tracks being played). In one embodiment, the sound effects can serve to provide auditory feedback to a user of the portable media device. A user interface can facilitate a user's selection of sound effect usages, types or characteristics.

An apparatus generating audio cues for content indicative of the position of audio objects within the content comprising:

an audio processor receiving raw audio tracks for said content and information indicative of the positions of at least some of said audio tracks within frames of said content, said audio processor generating corresponding audio parameters;

an authoring tool receiving said audio parameters and generating encoding coefficients, said audio parameters including audio cue of the position of audio objects corresponding to said tracks in at least one spatial dimension; and

a first audio/video encoder receiving an input and encoding said input into an audio visual content having visual objects and audio objects, said audio objects being disposed at location corresponding to said one spatial position, said encoder using said encoding coefficients for said encoding.

The present invention provides an audio enhancement system which is achieved by processing a duplicate of a recording or audio file and creating therefrom at least two identical secondary signals or two layers. One of the layers is the duplicated original and the other being an exact duplicate of that duplicated original. The enhanced audio files or recordings are used to enable the owner of the original audio file to purchase the enhanced audio. The user is enabled by the present system to compare the enhanced duplicate to the original to determine whether or not to purchase the enhanced audio.
