摘要： An apparatus for capturing audio information from a target location is provided. The apparatus comprises a first beamformer (110) being arranged in a recording environment and having a first recording characteristic, a second beamformer (120) being arranged in the recording environment and having a second recording characteristic and a signal generator (130). The first beamformer (110) is configured for recording a first beamformer audio signal and the second beamformer is configured for recording a second beamformer audio signal when the first beamformer (110) and the second beamformer (120) are directed towards the target location with respect to the first and the second recording characteristic. The first beamformer (110) and the second beamformer (120) are arranged such that a first virtual straight line, being defined to pass through the first beamformer (110) and the target location, and a second virtual straight line, being defined to pass through the second beamformer (120) and the target location, are not parallel with respect to each other. The signal generator (130) is configured to generate an audio output signal based on the first beamformer audio signal and on the second beamformer audio signal so that the audio output signal reflects relatively more audio information from the target location compared to the audio information from the target location in the first and the second beamformer audio signal.

摘要： An audio encoder, an audio decoder or an audio processor includes a filter (12) for generating a filtered audio signal, the filter having a variable warping characteristic, the characteristic being controllable in response to a time-varying control signal (16), the control signal indicating a small or no warping characteristic or a comparatively high warping characteristic. Furthermore, a controller (18) is connected for providing the time-varying control signal, which depends on the audio signal. The filtered audio signal can be introduced to an encoding processor (22) having different encoding algorithms, one of which is a coding algorithm adapted to a specific signal pattern. Alternatively, the filter is a post-filter receiving a decoded audio signal.

摘要： In order to determine a quantiser step size for quantising a signal comprising audio or video information, a first quantiser step size and an interference threshold are supplied (502). According to the invention, the actual interference introduced by means of the first quantizer step size is determined (504) and compared with the interference threshold (506). Even if the comparison indicates that the actually introduced interference is higher than the threshold, a second coarser quantizer step size is used (508), that is then used for the quantisation (514) if it emerges that the interference introduced by the coarser second quantizer step size is lower than the threshold or the interference introduced by the first quantiser step size (512). In this way, the quantisation interference is reduced during the coarsening of the quantisation and thus during an increase in the compression gain.

摘要： An audio encoder for encoding an audio signal comprises a first coding branch (400), the first coding branch comprising a first converter (410) for converting a signal from a time domain into a frequency domain. Furthermore, the audio encoder comprises a second coding branch (500) comprising a second time/frequency converter (523). Additionally, a signal analyzer (300/525) for analyzing the audio signal is provided. The signal analyzer, on the hand, determines whether an audio portion is effective in the encoder output signal as a first encoded signal from the first encoding branch or as a second encoded signal from a second encoding branch. On the other hand, the signal analyzer determines a time/frequency resolution to be applied by the converters (410, 523) when generating the encoded signals. An output interface includes, in addition to the first encoded signal and the second encoded signal, a resolution information identifying the resolution used by the first time/frequency converter and used by the second time/frequency converter.
