Abstract: A method for processing sound data is provided for the reconstruction of multi-channel audio data on the basis at least of data on a reduced number of channels and of spatialization data. A test is carried out to determine whether the spatialization data received are valid. If the test is positive, a spatialization value is predicted according to a per respective model of a plurality of models. A prediction model is chosen on the basis of the spatialization values thus predicted and on the basis of the spatialization data received, to permit, in case of subsequent reception of defective spatialization data, a prediction according to this chosen model of a spatialization value and to use this predicted spatialization value for the reconstruction of the multi-channel audio data.

Abstract: Automatic measurements are made of audio presence and level in an audio signal by direct processing of an MPEG data stream representing the audio signal, without reconstructing the audio signal. Sub-band data is extracted from the data stream, and the extracted sub-band data is dequantized and denormalized. An audio level for the dequantized and denormalized sub-band data is measured without reconstructing the audio signal. Channel characteristics are used in measuring the audio level of the sub-band data, wherein the channel characteristics are used to weight the measured levels. The measured levels are compared against at least one threshold to determine whether an alarm should be triggered.

Abstract: An audio user interface is provided in which items are represented in an audio field by corresponding synthesized sound sources from where sounds related to the items appear to emanate. An audio cursor, in the form of a synthesised sound source from which a distinctive cursor sound emanates, is movable in the audio field under user control.

In one embodiment, this audible indication also indicates the current distance between the cursor and item-representing sound source and also the direction of the latter from the cursor.

Abstract: Systems and methods for enhanced media playback are disclosed. According to one aspect, during media playback, auxiliary (or secondary) media can be integrated with primary media. For example, an electronic device offering media playback can not only play back media item data but can also play back other auxiliary media data.

Another aspect pertains to how and when auxiliary media data is to be presented (e.g., played) by an electronic device. Another aspect pertains to updating or refreshing auxiliary media data. Still another aspect pertains to restricting presentation of primary media by an electronic device unless auxiliary data is also presented.

Abstract: An audio system receives a multi-channel signal which is fed to a controller (121) that generates a first drive signal for a first sound emitter (111) by combining signals of a plurality of the channels. The first drive signal has a signal component contribution from a first bandwidth of each channel of the multi-channel signal.

Abstract: A reverberant characteristic of an acoustic space is superimposed on an audio signal that is received by an apparatus. The apparatus decomposes the audio signal into an estimated original dry signal component and an estimated reverberant characteristic of the acoustic space. Estimation of the original dry signal component and the reverberant characteristic of the acoustic space is based on determination of an estimated impulse response of the acoustic space from the received audio signal. Once the audio signal is decomposed, the estimated original dry signal component and the estimated reverberant characteristic of the acoustic space may be independently modified by the apparatus. The modified or unmodified estimated original dry signal component and estimated reverberant characteristic of the acoustic space may be combined by the apparatus to produce one or more adjusted frequency spectra.
