  • Publication number: 20060025993
    Abstract: An audio system comprises a post-processor (12) arranged to alter successive fragments of a decoded audio signal (14) to provide successive fragments of post-processed audio signal (16). A masking threshold generator (20) provides an estimate of a masking threshold ( ) for successive fragments of post-processed audio signal (16). A noise level generator (17) provides an estimate of a noise level ( ) for successive fragments of the post-processed audio signal (16). A distortion generator (17) determines a degree (D) to which the noise level exceeds the masking threshold for successive fragments of the post-processed audio signal (16). A regulator (18) controls the post-processor according to the degree to which the noise levels exceed the masking threshold.

  • Publication number: 20050281416
    Abstract: To improve the aural sensation from an input signal of an audio reproduction system a bandwidth extension device can be used. The bandwidth extension device includes a first and a second signal path and an analyzer for selecting the created signal which fits most for the current input signal.

  • Publication number: 20050219222
    Abstract: In a touch sensor the change in electrical characteristics (impedance, piezo-voltage) of spacing elements (13,14,15,25), provided with an conducting, resistive or piezo-electric layer (15, 25), are measured to determine the sensing area.

  • Publication number: 20050213522
    Abstract: Disclosed is a method of encoding a multichannel signal including at least a first signal component (y) and a second signal component (r). The method comprises the steps of determining a set of filter parameters (Fp) of a prediction filter (201) such that the prediction filter provides an estimate (P) of the second signal component when receiving the first signal component as an input; and representing the multichannel signal as the first signal component and the set of filter parameters. Further disclosed are a corresponding arrangement for encoding a multichannel signals and a corresponding method and arrangement for decoding such a signal.

  • Publication number: 20050213528
    Abstract: The present invention relates to a method for a service provider to distribute an audio signal to a listener. Before delivering the audio signal to the listener, the audio impression of the audio signal is personalized to the listener. The personalizing could e.g. be performed by filtering the audio signal using a set of head related transfer functions (HRTFs) defined by parameters being specific for the listener. This is for minimizing the interest of performing illegal copying of the audio signal. The invention further relates to a method of playing back a distributed audio signal and a playback device for playing back a distributed audio signal, where the personalization is detected and used as a watermark, which is identified and interpreted before playing back the distributed audio.

  • Publication number: 20050162410
    Abstract: In a touch sensor the change in pixel impedance is measured from the sensing area directly (passive matrix) or through the address transistors (AMLCD) associated with the sensing area.

  • Publication number: 20050146986
    Abstract: A shuffle device (5) for players with different types of storage medium such as CD (1), DVD (2), hard disk drive (3) or random access memory (4). The shuffle device (5) is provided in a particular central control device (7) such as a remote control, a hand-held computer, a personal digital assistant or palmtop that is valuable for all the players of the (home) system. As the shuffle device (5) comprising hardware and software is needed only once and can be used for different players, the cost of each player is reduced. Meta data that are downloaded from the Internet, derived from a smart card, added by means of a voice-to-text-converter or typed in by the user can be displayed on the central control system (7).

  • Publication number: 20050141721
    Abstract: Disclosed is a method of encoding a multichannel signal, such as a stereophonic audio signal, including at least a first signal component (L) and a second signal component (R). The method comprises the steps of transforming at least the first and second signal components by a predetermined transformation into a principal signal (y) including most of the signal energy and at least one residual signal (r) including less energy than the principal signal, the predetermined transformation being parameterised by at least one transformation parameter (( ) and representing the multichannel signal at least by the principal signal and the transformation parameter. Further disclosed are a corresponding arrangement for encoding a multichannel signals and a corresponding method and arrangement for decoding such a signal.

  • Publication number: 20050078831
    Abstract: The invention relates to a circuit (100) for enhancing a stereo sound signal, represented by a left input signal (L) and a right signal (R). By only using the parts of the left input signal (L) and the right input signal (R) that are not correlated to each other, unwanted stereo enhancement of, for example, dialogs is eliminated. On the other hand, the stereo image of sound effects like explosions will be enhanced. Most movies are properly mixed for this. In one embodiment of the invention, a center signal is generated by averaging the left input signal and the right input signal. The invention relates to a method of enhancing a stereo sound signal. The invention also relates to an apparatus (500) for reproducing sound.

  • Publication number: 20050013446
    Abstract: An audio system includes a circuit (12) for processing an audio signal, which circuit (12) having an input (20) for receiving the audio signal and an output (26) for supplying an output signal. The circuit (12) further includes a harmonics generator (22) coupled to the input (20) for generating harmonics of the audio signal and an adding circuit (24) coupled to the input (20) as well as to the harmonics generator (22) for supplying a sum of the audio signal and the generated harmonics to the output (26). The harmonics generator (22) includes an integrator (34) for integrating the audio signal and, coupled thereto, a resetting circuit (36) for resetting the integrator (34) at resetting times.
