摘要： An audio system comprises a receiver (301) for receiving an audio signal, such as an audio object or a signal of a channel of a spatial multi-channel signal. A binaural circuit (303) generates a binaural output signal by processing the audio signal. The processing is representative of a binaural transfer function providing a virtual sound source position for the audio signal. A measurement circuit (307) generating measurement data indicative of a characteristic of the acoustic environment and a determining circuit (311) determines an acoustic environment parameter in response to the measurement data. The acoustic environment parameter may typically be a reverberation parameter, such as a reverberation time. An adaptation circuit (313) adapts the binaural transfer function in response to the acoustic environment parameter. For example, the adaptation may modify a reverberation parameter to more closely resemble the reverberation characteristics of the acoustic environment.

摘要： A multi-channel audio encoder (10) for encoding a multi-channel audio signal (101), e.g. a 5.1 channel audio signal, into a spatial down-mix (102), e.g. a stereo signal, and associated parameters (104, 105). The encoder (10) comprises first and second units (110, 120). The first unit (110) encodes the multi-channel audio signal (101) into the spatial down-mix (102) and parameters (104). These parameters (104) enable a multi-channel decoder (20) to reconstruct the multi-channel audio signal (203) from the spatial down-mix (102). The second unit (120) generates, from the spatial down-mix (102), parameters (105) that enable the decoder to reconstruct the spatial down-mix (202) from an alternative down-mix (103), e.g. a so-called artistic down-mix that has been manually mixed in a sound studio. In this way, the decoder (20) can efficiently deal with a situation in which an alternative down-mix (103) is received instead of the regular spatial, down-mix (102). In the decoder (20), first the spatial down-mix (202) is reconstructed from the alternative down-mix (103) and the parameters (105). Next, the spatial down-mix (202) is decoded into the multi-channel audio signal (203).

摘要： A basic idea of the present invention is to selectively employ one of at least two different feature extraction processes when generating a biometric template of an individual. An individual offers a physiological property, such as a fingerprint, an iris, an ear, a face, etc., from which biometric data can be derived, to a sensor of an enrolment authority. In the following, the property to be discussed will be fingerprints, even though any suitable biometric property may be used. From the fingerprint, a positional reference point of the biometric data is derived. The derivation of the positional reference point may be accomplished using any appropriate method out of a number of known methods. Such a reference point could be the location of a core, a delta, a weighted average of minutiae coordinates, or alike. Typically, the reference point includes a core of a fingerprint expressed as a three-dimensional coordinate denoted by means of xr, yr, and angle αr. A contribution indicator is calculated for the derived positional reference point, and it is determined whether the derived positional reference point can be considered reliable. Depending on the reliability of the derived reference point, one of the two different feature extraction processes is selected; either the first feature set is extracted using a method which is invariant of the derived reference point, or a method is used taking into account the derived reference point. The better the estimation of the reference point is, the more reliable the reference point-dependent extraction method is. Finally, the biometric template is generated using the extracted first feature set.
摘要翻译：本发明的基本思想是当生成个体的生物特征模板时，选择性地采用至少两种不同的特征提取过程中的一种。个体向生物特征提供生物特征，例如指纹，虹膜，耳朵，面部等，从中可以将生物特征数据导出到注册机构的传感器。在下文中，要讨论的属性将是指纹，即使可以使用任何合适的生物特征属性。从指纹，导出生物特征数据的位置参考点。可以使用多种已知方法中的任何适当的方法来实现位置参考点的推导。这样的参考点可以是核心的位置，三角形，细节坐标的加权平均值，或类似的。通常，参考点包括表示为由xr，yr和角度αr表示的三维坐标的指纹的核心。针对导出的位置参考点计算贡献指标，并且确定导出的位置参考点是否可以被认为是可靠的。根据导出的参考点的可靠性，选择两个不同特征提取过程之一; 使用导出的参考点不变的方法来提取第一特征集，或者使用考虑到导出的参考点的方法。参考点的估计越好，参考点依赖性提取方法越可靠。最后，使用提取的第一特征集生成生物特征模板。

摘要： An encoding device (1) and method convert a set of signals (l, r) into a dominant signal (m) containing most signal energy, a residual signal (s) containing a remainder of the signal energy, and signal parameters (IID, ICC) associated with the conversion. The dominant signal (m) and selected parts of the residual signal (s) are encoded. Selecting parts of the residual signal involves a residual signal (s′) passing perceptually relevant parts of the residual signal (s), attenuating perceptually less relevant parts of the residual signal and suppressing least relevant parts of the residual signal. An associated decoding device (2) and method decode the encoded dominant signal and the encoded residual signal so as to produce a decoded dominant signal (m′u) and a decoded residual signal (s′mod) respectively. A synthetic residual signal (s′syn) is derived from the decoded dominant signal (m′u) and is attenuated so as to produce an attenuated synthetic residual signal (s′syn,mod). The attenuated synthetic residual signal (s′syn,mod) and the decoded residual signal (s′mod) are combined to produce a reconstructed residual signal (s′). The decoded dominant signal (m′) and the reconstructed residual signal (s′) are then converted into a set of output signals (l′, r′).

摘要： A method and a device are described for processing a stereo signal obtained from an encoder, which encodes an N-channel audio signal into spatial parameters (P) and a stereo down-mix comprising first and second stereo signals (L0, R0). A first signal and a third signal are added in order to obtain a first output signal (Low), wherein the first signal (L0wL) comprises the first stereo signal (L0) modified by a first complex function (g1), and the third signal (L0wR) comprises the second stereo signal (R0) modified by a third complex function (g3). A second signal and a fourth signal are added to obtain a second output signal (R0w). The fourth signal (R0wR) comprises the second stereo signal (R0) modified by a fourth complex function (g4), and the second signal (R0wL) comprises the first stereo signal (L0) modified by a second complex function (g2). The complex functions (g1, g2, g3, g4) are functions of the spatial parameters (P) and are chosen to be such that an energy value of the difference (L0wL,R0wL) between the first signal and the second signal is larger than or equal to the energy value of the sum (L0wL+R0wL) of the first and the second signal, and the energy value of the difference (R0wR−L0wR) between the fourth signal and the third signal is larger than or equal to the energy value of the sum (R0wR+L0wR) of the fourth signal and the third signal.

摘要： A method of encoding input signals (l, r) to generate encoded data (100) is provided. The method involves processing the input signals (l, r) to determine first parameters (φ1, φ2) describing relative phase difference and temporal difference between the signals (l, r), and applying these first parameters (φ1, φ2) to process the input signals to generate intermediate signals. The method involves processing the intermediate signals to determine second parameters (α; IID, ρ) describing angular rotation of the first intermediate signals to generate a dominant signal (m) and a residual signal (s), the dominant signal (m) having a magnitude or energy greater than that of the residual signal (s). These second parameters are applicable to process the intermediate signals to generate the dominant (m) and residual (s) signals. The method also involves quantizing the first parameters, the second parameters, and dominant and residual signals (m, s) to generate corresponding quantized data for subsequent multiplexing to generate the encoded data (100).
