    摘要： A panel-shaped acoustic wave generator (1A; 1B; 101) comprises one or more planar plates (2,3;102,103). In an embodiment two planar plates (2, 3; 102, 103) are arranged substantially parallel at a distance (D) from each other, while the wave generator (1A;1B;101) further includes an acoustic transducer unit (4; 110A) for causing at least one of the plates to vibrate and a motional feedback unit (10; 110B). The motional feedback unit (10; 110B) comprise an integrated motion sensor (9) which comprises a first sensor component (11; 111B) mechanically coupled to a first plate (2; 102) and a second sensor component (12; 112B) mechanically coupled to a second plate (3; 103). In a specific embodiment, the wave generator is implemented as a display device (100) wherein the feedback means comprise at least one display cell (110B) of the display device.

    摘要： A device is arranged for producing a driving signal (VM) for a transducer (7), such as a loudspeaker. The driving signal has a frequency substantially equal to a resonance frequency of the transducer and an amplitude controlled by an external signal (VE). The device is arranged for automatically adjusting the frequency of the driving signal to the resonance frequency of the transducer, using a control path (8). The device may be part of a frequency adaptation device (1) for adapting a frequency range of an audio signal to the transducer (7).

    摘要： 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.

    摘要： 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.

    摘要： An audio signal may be enhanced by adding enhancement signals, such as harmonics and/or sub-harmonics of the signal's bass components. To avoid any unwanted enhancement signals during soft passages or speech, it is proposed to monitor the audio signal for tonal signal components in a frequency range and to only add the enhancement signals if such tonal signals are detected. A tonal detector (3) may comprise sine and cosine generators whose frequency is preferably equal to a dominant frequency of the frequency range.

    摘要： The present invention relates to a method and a media system of/for generation of at least one output signal (HPL, (HPR) from at least one input signal from a second set of sound signals (M) having a related second set of Head Related Transfer Functions. The media system can be a TV, a CD player, a DVD player, a Radio, a display, an amplifier, a headphone or a VCR. Said method includes the steps of determining, for each signal in the second set of sound signals, a weighted relation (14) comprising at least one signal from a third set of intermediate sound signals (CHI1, CHI2) and at least one weight value (Weights); determining a first set of Head Related Transfer Functions (HRTFs) based on the second set of sound signals, the second set of Head Related Transfer Functions and the weighted relation; and transferring at least one signal from the third set of intermediate sound signals by means of at least one HRTF from said first set of Head Related Transfer Functions in order to generate at least one output signal belonging to said first set of sound signals. Hereby, in the end, fewer HRTFs are determined for a subsequent transfer of input signal(s) to output signal(s). Accordingly few convolutions are required.
