Spectral compensation filter for close-range sound source

A method of generating a signal for driving a first linear array of a sound source. The first linear array of sound sources includes a primary sound source and one or more secondary sound sources. The method comprises the steps of receiving an audio signal for a first channel of the audio system, deriving a first signal and a second signal from the audio signal, applying a low pass filter to the second signal to generate a second drive signal for driving the one or more secondary sound sources, and applying a corresponding high frequency shelf filter to the first signal to generate a first drive signal for driving the primary sound source. A computer program product and an audio system for generating a flattened sound field are also provided. 一种生成用于驱动声源的第一线阵列的信号的方法。声源的第一线阵列包括主声源和一个或多个副声源。该方法包括以下步骤：接收用于音频系统的第一声道的音频信号，从所述音频信号中导出第一信号和第二信号，将低通滤波器应用于所述第二信号以生成用于驱动所述一个或多个副声源的第二驱动信号，以及将相应的高频搁架滤波器应用于所述第一信号以生成用于驱动所述主声源的第一驱动信号。还提供了一种用于生成平整声场的计算机程序产品和音频系统。
