20130282386 | MULTI-CHANNEL ENCODING AND/OR DECODING - A method comprising: receiving input signals for multiple channels; and parameterizing the received input signals into parameters defining multiple different object spectra and defining a distribution of the multiple different object spectra in the multiple channels. | 10-24-2013 |
20130332837 | METHODS AND APPARATUS FOR SOUND MANAGEMENT - Systems and techniques for location based sound management. Information associated with a display is defined or selected based on user inputs and sounds associated with responsive locations of the display. Defining of the information associated with the display may be based at least in part on user touches to a touch screen display. Parameters for playback are also selected, such as a number of audio channels, based on user inputs that may similarly comprise user touches to the touch screen display. Playback parameters may be changed during playback based on user inputs occurring during playback. | 12-12-2013 |
20140029767 | Downmixing Control - An apparatus including an audio mixer configured to mix at least two audio channels of an audio signal; and a sensor configured to sense motion and/or orientation of the apparatus. The audio mixer is configured to change mixing of the at least two audio channels based, at least partially, on an output from the sensor regarding the sensed motion and/or orientation of the apparatus. | 01-30-2014 |
20140169754 | Spatial Seeking In Media Files - A method, apparatus, and computer program product are provided in order to playback video and/or audio files wherein a desired segment is selected and played back based on its spatial audio content. In the context of a method, playback of media data is provided. The method may include generating one or more spatial seek points for the media data and causing display of information corresponding to the one or more spatial seek points. The method may further include performing the generation of the one or more seek points based on receiving a request for spatial seek points, automatically upon receiving the media data or upon starting playback of the media data, or based on the format of the media data. The method may further include receiving a selection of one of the one or more spatial seek points and providing for playback of the media data from a time point corresponding to the selected spatial seek point. A corresponding apparatus and a computer program product are also provided. | 06-19-2014 |
20140337742 | METHOD, AN APPARATUS AND A COMPUTER PROGRAM FOR DETERMINATION OF AN AUDIO TRACK - An audio processing apparatus is provided. The apparatus comprising an audio analysis unit configured to obtain a group of audio signals, each audio signal associated with an image of a group of images, the group of images being provided for a presentation having an assigned overall viewing time with each image having an assigned viewing time, and to analyze at least one of the audio signals to determine one or more intermediate audio signals for determination of an audio track having a first duration, which first duration essentially covers said assigned overall viewing time. The apparatus further comprises an audio track determination unit configured to compose the audio track having said first duration on basis of said one or more intermediate audio signals. The apparatus may further comprise a classification unit configured to obtain a plurality of audio signals, each audio signal associated with an image of a plurality of images, to obtain a plurality of location indicators, each location indicator associated with an image of the plurality of images, and to determine the group of images as a subset of the plurality of images such that the group comprises images having location indicator referring to a first location associated therewith. | 11-13-2014 |
20140341547 | AN APPARATUS AND METHOD OF AUDIO STABILIZING - A method comprising: determining a spatial audio signal; determining an apparatus motion parameter; and stabilizing the spatial audio signal dependent on the apparatus motion parameters. | 11-20-2014 |
20140369506 | METHOD, AN APPARATUS AND A COMPUTER PROGRAM FOR MODIFICATION OF A COMPOSITE AUDIO SIGNAL - The present invention provides an arrangement, e.g. a method, an apparatus and a computer program. The arrangement comprises obtaining information indicative of spatial positions of one or more sound sources within an audio image of a composite audio signal, obtaining information indicative of the types of the one or more sound sources, determining, for each of the one or more sound sources, a position in a display of the apparatus indicative of the spatial position of the sound source and causing an apparatus to display an item representing the sound source in the determined position in the display, wherein the item representing the sound source is determined on basis of the type of the sound source. The arrangement further comprises receiving an indication of a user action associated with an item indicative of a first sound source, determining an indication of a user selected modification of the audio image on basis of the user action, and modifying the composite audio signal in accordance with the user selected modification. | 12-18-2014 |
20140372107 | AUDIO PROCESSING - A technique for creating audio objects on basis of a source audio signal is provided. According to an example embodiment, the technique comprises obtaining a plurality of frequency sub-band signals, each representing a directional component of a source audio signal in the respective frequency sub-band, obtaining an indication of dominant sound source direction for one or more of said frequency sub-band signals, and creating one or more audio objects on basis of said plurality of frequency sub-band signals and said indications, said creating comprising deriving one or more audio object signals, each audio object signal comprising a respective directional signal determined on basis of frequency sub-band signals for which dominant sound source direction falls within a respective predetermined range of source directions and deriving one or more audio object direction indications for said one or more audio object signals, each audio object direction indication derived on basis of dominant sound source directions for the frequency sub-band signals used for determining the respective directional signal. | 12-18-2014 |
