摘要： An input audio signal (101) is separated into input audio signal components (X(k,b)). A set of two or more band branches (105e) provides output audio signal components (Y(k,b)). The set of band branches (105e) comprises one or more compressor branches Each compressor branch compresses a respective input audio signal component (X(k,b)) into a respective output audio signal component (Y(k,b)). A summed audio signal (y(t)) is generated by summing the output audio signal components (Y(k,b)). A residual audio signal (v(t)) is a difference between the input audio signal (101) and the summed audio signal (y(t)) A virtual bass signal (w(t)) comprises one or more harmonics of the residual audio signal (v(t)). An output audio signal (103) is generated by summing the summed audio signal (y(t)) and the virtual bass signal (w(t)).

摘要： The disclosure is based on the finding that acoustic near-field transfer functions indicating acoustic near-field propagation channels between loudspeakers and ears of a listener can be employed to pre-process audio signals. Therefore, acoustic near-field distortions of the audio signals can be mitigated. The pre-processed audio signals can be presented to the listener using a wearable frame, wherein the wearable frame comprises the loudspeakers for audio presentation. The disclosure can allow for a high quality rendering of audio signals as well as a high listening comfort for the listener. The disclosure can provide the following advantages. By means of a loudspeaker selection as a function of a spatial audio source direction, cues related to the listener's ears can be generated, making the approach more robust with regard to front/back confusion. The approach can further be extended to an arbitrary number of loudspeaker pairs.

摘要翻译：本公开是基于以下发现：可以采用指示收听者的扬声器和耳朵之间的声学近场传播信道的声学近场传递函数来预处理音频信号。因此，可以减轻音频信号的声学近场失真。预处理的音频信号可以使用可穿戴的框架呈现给收听者，其中，可穿戴的框架包括用于音频呈现的扬声器。该公开可以允许音频信号的高质量呈现以及对听众的高听觉舒适度。本公开可以提供以下优点。通过扬声器选择作为空间音频源方向的函数，可以产生与听众的耳朵相关的线索，使得该方法在前/后混淆方面更加坚固。该方法可以进一步扩展到任意数量的扬声器对。
