摘要： A binaural object-oriented audio decoder including a decoder device to decode and render an audio object based on head-related transfer function (HRTF) parameters. The decoder device positions an audio object in a virtual three-dimensional space. The HRTF parameters are based on elevation, azimuth, and distance parameters and correspond to the position of the audio object in the virtual three-dimensional space. The binaural object-oriented audio decoder is configured to receive the HRTF parameters that vary for the elevation and azimuth parameters only. The binaural object-oriented audio decoder further includes a distance processor for modifying the received HRTF parameters according to a received desired distance parameter. The modified HRTF parameters are used to position the audio object in the three-dimensions at the desired distance. The modification of the HRTF parameters is based on a predetermined distance parameter for the received HRTF parameters.

摘要： A spatial decoder unit (23) is arranged for transforming one or more audio channels (s; l, r) into a pair of bin-aural output channels (Ib, rb). The device comprises a parameter conversion unit (234) for converting the spatial parameters (sp) into binaural parameters (bp) containing binaural information. The device additionally comprises a spatial synthesis unit (232) for transforming the audio channels (L, R) into a pair of binaural signals (Lb, Rb) while using the binaural parameters (bp). The spatial synthesis unit (232) preferably operates in a transform domain, such as the QMF domain.

摘要： In summary, this application describes a psycho-acoustically motivated, parametric description of the spatial attributes of multichannel audio signals. This parametric description allows strong bitrate reductions in audio coders, since only one monaural signal has to be transmitted, combined with (quantized) parameters which describe the spatial properties of the signal. The decoder can form the original amount of audio channels by applying the spatial parameters. For near-CD-quality stereo audio, a bitrate associated with these spatial parameters of 10 kbit/s or less seems sufficient to reproduce the correct spatial impression at the receiving end.
摘要翻译：总之，本应用程序描述了多声道音频信号的空间属性的心理声学动机的参数描述。该参数描述允许音频编码器中的强比特率降低，因为只需要传输一个单声道信号，并与描述信号的空间属性的（量化）参数组合。解码器可以通过应用空间参数形成原始数量的音频通道。对于近CD质量的立体声音频，与这些10 kbit / s或更小的空间参数相关联的比特率似乎足以在接收端再现正确的空间印象。

摘要： An audio system comprises an encoder (209) which encodes audio objects in an encoding unit (403) that generates a down-mix audio signal and parametric data representing the plurality of audio objects. The down-mix audio signal and parametric data is transmitted to a decoder (215) which comprises a decoding unit (301) which generates approximate replicas of the audio objects and a rendering unit (303) which generates an output signal from the audio objects. The decoder (215) furthermore contains a processor (501) for generating encoding modification data which is sent to the encoder (209). The encoder (209) then modifies the encoding of the audio objects, and in particular modifies the parametric data, in response to the encoding modification data. The approach allows manipulation of the audio objects to be controlled by the decoder (215) but performed fully or partly by the encoder (209). Thus, the manipulation may be performed on the actual independent audio objects rather than on approximate replicas thereby providing improved performance.

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).

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： The application describes a child monitoring system and method for detecting and discriminating between children and adults passing under a sensor that is independent of the position of the sensor in relation to the subject. The system determines a distance to a surface on which a person can stand, and calculates a reference distance from this distance and a desired threshold. When a person enters the sensor range, the distance to the top of the person's head is compared with the reference distance to determine whether the person is an adult or a child. An alert can be provided when a child is detected as opposed to an adult, and alerts can be suppressed if an adult is in the vicinity.

摘要： A selected channel of a multi-channel signal which is represented by frames composed from sampling values having a high time resolution can be encoded with higher quality when a wave form parameter representation representing a wave form of an intermediate resolution representation of the selected channel is derived, the wave form parameter representation including a sequence of intermediate wave form parameters having a time resolution lower than the high time resolution of the sampling values and higher than a time resolution defined by a frame repetition rate. The wave form parameter representation with the intermediate resolution can be used to shape a reconstructed channel to retrieve a channel having a signal envelope close to that one of the selected original channel. The time scale on which the shaping is performed is shorter than the time scale of a framewise processing, thus enhancing the quality of the reconstructed channel. On the other hand, the shaping time scale is larger than the time scale of the sampling values, significantly reducing the amount of data needed by the wave form parameter representation.
