The attenuation of the audio signal containing the at least one main speech is carried out by means of a hardware- and/or software-implemented attenuation device which is provided for attenuating the audio signal component containing the at least one main speech and forms a functional part of the device.

Thus, the audio signal can be divided into a plurality of main speeches, wherein the audio signal contains at least one main speech. For this purpose, the audio signal is analyzed by means of a suitable analysis device or analysis algorithm at least with respect to the audio signal component containing the at least one main speech and divided accordingly. The analysis of the audio signal can be based on specific predefinable or predefinable acoustic properties, ie for example amplitude(s) and/or frequency(s) of the audio signal components comprising the main speech, for example stored in the storage device (data storage). The analysis of the audio signal can thus eg be performed by equalizing with the acoustic signal a definable or predefined acoustic characteristic, ie eg amplitude(s) and/or frequency(s), of the audio signal component comprising the main speech. As shown below, a division of the audio signal can also be performed, wherein a central audio signal component is obtained, which usually contains at least one main speech. The division of the provided audio signal into a plurality of audio signal components can be carried out by means of extraction means or division means associated with the extraction means or capable of being associated with the extraction means, the division means being arranged to divide the provided audio signal.

根据研究多样的音频信号或音乐作品获得如下知识:通常中央音频信号分量包含至少一个主语音,因此,通过相应地划分音频信号获得中央音频信号分量通常能够获得包含至少一个主语音的音频信号分量。The following knowledge is gained from studying various audio signals or musical compositions: usually the central audio signal component contains at least one main speech, thus obtaining the central audio signal component by dividing the audio signal accordingly usually results in an audio signal component containing at least one main speech.
每个从音频信号的划分中获得的音频信号分量原理上能够混音到音频输出装置的特定的音频输出通道上或者经由音频所述装置的特定的音频输出通道输出。换言之,每个音频信号分量能够与音频输出装置的两个音频输出通道之一关联,经由所述音频输出通道还输出各自的音频信号分量。在输出音频信号期间,左侧和右侧的音频信号分量通常混合到音频输出装置的右侧和/或左侧的音频输出通道上;在输出音频信号期间,左侧的音频信号分量通常经由音频输出装置的左侧的音频输出通道和右侧的音频输出通道输出。对于所提及的、通常包含至少一个主语音的中央音频信号分量适用的是:所述中央音频信号分量能够根据衰减度或删除度例如衰减地按比例划分的方式在两个音频输出通道之一或两者上或经由两个音频输出通道之一或两者混音或输出,或能够以(完全)删除的方式而不被混音或输出。Each audio signal component obtained from the division of the audio signal can in principle be mixed onto a specific audio output channel of the audio output device or output via a specific audio output channel of the audio output device. In other words, each audio signal component can be associated with one of the two audio output channels of the audio output device, via which audio output channel the respective audio signal component is also output. During output of an audio signal, the left and right audio signal components are typically mixed onto the right and/or left audio output channels of the audio output device; during output of the audio signal, the left audio signal component is typically The audio output channel on the left side of the output device and the audio output channel on the right side are output.

Mixed or output on either or both or via one or both of the two audio output channels, or can be (completely) deleted without being mixed or output.
将所提供的音频信号划分成各自的音频信号分量能够借助于源分离装置执行。相应的源分离装置例如能够通过源分离算法实施。用于源分离的适合的设备或适合的源分离算法例如在德国专利DE 10 2012 025 016 B3中描述,其公开内容通过参考并入本文。The division of the provided audio signal into the respective audio signal components can be performed by means of the source separation device. A corresponding source separation device can be implemented, for example, by means of a source separation algorithm. Suitable devices for source separation or suitable source separation algorithms are described, for example, in
包含至少一个主语音的音频信号分量的衰减、即例如中央音频信号分量的衰减尤其能够通过借助滤波装置、尤其阻隔滤波装置、优选带阻滤波装置从音频信号中过滤音频信号分量来执行。对此,衰减装置能够构成为包含频率上限和频率下限的滤波装置或包括这种滤波装置。能够选择滤波装置的频率上限和频率下限,使得滤除要滤除的主语音的频率分量。因此,该设备能够包括如下滤波装置,所述滤波装置由于相应的上限频率和下限频率而设置用于滤除要滤除的主语音的频率分量。Attenuation of the audio signal component comprising the at least one main speech, ie for example of the central audio signal component, can in particular be performed by filtering the audio signal component from the audio signal by means of a filtering device, in particular a blocking filtering device, preferably a band-rejecting filtering device. For this purpose, the attenuation device can be designed as a filter device comprising an upper frequency limit and a lower frequency limit or as such a filter device. The upper and lower frequency limits of the filtering means can be selected such that the frequency components of the main speech to be filtered are filtered out. Therefore, the apparatus can comprise filtering means arranged to filter out frequency components of the main speech to be filtered out due to the respective upper and lower frequencies.
