摘要： An audio signal processor receives a plurality of encoded multi-channel audio signals. A multi-channel decoder (105) decodes a first encoded multi-channel signal to generate a first decoded multi-channel signal. A generator (109) generates an encoded further audio signal by selecting audio encoding data from at least a second encoded multi-channel audio signal such that a number of channels of the encoded further audio signal comprising audio encoding data from the second encoded multi-channel audio signal is less than a number of channels in the second encoded multi-channel signal. Thus, a channel reduction is performed in the encoded data domain. A further decoder (111) generates a further decoded signal by decoding the further encoded audio signal. A combiner (107) combines the first decoded multi-channel signal and the further decoded signal to generate a multi-channel output signal. An exciting user experience can be provided while maintaining low complexity and resource usage.
摘要翻译：音频信号处理器接收多个编码的多声道音频信号。多通道解码器（105）对第一编码多通道信号进行解码以产生第一解码多通道信号。发生器（109）通过从至少第二编码的多声道音频信号中选择音频编码数据来生成编码的另外的音频信号，使得编码的另外的音频信号的信道数量包括来自第二编码多声道的音频编码数据音频信号小于第二编码多声道信号中的多个声道。因此，在编码数据域中执行信道减少。另外的解码器（111）通过解码另外编码的音频信号来产生进一步的解码信号。组合器（107）组合第一解码多通道信号和另外的解码信号以产生多通道输出信号。可以提供令人兴奋的用户体验，同时保持低复杂性和资源使用。

摘要： A sound processing system receives a stereo signal which, by a segmenter (109) is divided into stereo time-frequency signal segments, each of which may correspond to a frequency domain sample in a given time segment. A decomposer (111) decomposes the time-frequency signal segments by for each pair of stereo time-frequency signal segments performing the steps of: determining a similarity measure indicative of a degree of similarity of the stereo time frequency signal segments; generating a sum time-frequency signal segment as a sum of the stereo time-frequency signal segments; and generating a centre time-frequency signal segment from the sum time-frequency signal segment and a pair of side stereo time-frequency segments from the pair of stereo time-frequency signal segments in response to the similarity measure. A signal generator (113) then generates a multi-channel signal comprising a centre signal generated from the sum time-frequency signal segments and side signals generated from the side stereo time-frequency segments.

摘要： An apparatus for spatial sound reproduction comprises a receiver (101) for receiving a multi-channel audio signal. An analyzer (107) determines a spatial property of the multi-channel audio signal, such as a spatial complexity or organization. A selection processor (109) then selects a reproduction mode from a plurality of sound reproduction modes where the multi-channel sound reproduction modes employ different spatial rendering techniques. A reproduction circuit (103) then drives a set of loud-speakers (105) to reproduce the multi-channel audio signal using the selected reproduction mode. The switching between the reproduction modes may be fast (e.g. in the order of 100 ms to 10 secs) thereby allowing a short term adaptation of the reproduction mode to the signal characteristics. The approach may in particular provide an improved spatial experience to a listener.

摘要： An audio system comprises a receiver which receives an input audio signal. A decomposer (103) decomposes the audio signal into at least a transient component signal and a non-transient component signal. An output circuit (105, 107, 109) then generates a first output audio signal in response to a weighted combination of the transient component signal and the non-transient component signal. In the combination the weighting of the transient component signal is different than the weighting of the non-transient component signal. A new signal with different emphasis of specific sound characteristics can be achieved. The approach may be particularly suited to generation of new spatial audio channels from an existing spatial audio channel, such as in particular the generation of an elevated channel from audio signals of a lower channel.
