Abstract: The quality of music output from audio systems is improved by simulating the effect of low frequency signals in the human ear. This thus allows listeners to perceive the lower frequency signals, even though the speakers may be incapable of providing such low frequency outputs. Method and systems provided for processing enhancing bass effect in audio signals. Said method and systems result in the bass enhancement being computationally less intensive. The bass effect enhancement techniques described are based on the response of sine and cosine transfer functions and on the directional independence of low frequency components. The human ear is unable to resolve directions from low frequency components. The bass effect enhancement technique alternatively is based on response of an exponential transfer function.
Abstract translation: 通过模拟人耳中低频信号的影响，改善了音频系统音乐输出的质量。 因此，即使扬声器不能提供这样的低频输出，因此允许听众感知较低频率信号。 用于处理音频信号中加强低音效果的方法和系统。 所述方法和系统导致低音增强在计算上不太密集。 所描述的低音效果增强技术是基于正弦和余弦传递函数的响应以及低频分量的方向独立性。 人耳不能解决低频部件的方向。 低音效果增强技术或者基于指数传递函数的响应。
