摘要:
The invention provides an audio signal processing system in which a magnitude spectrum of a frequency domain audio signal is processed based on a measure of multipath interference. The processing keeps the magnitude spectrum approximately fixed during periods of multipath interference, for example by replacing it with a temporally smoothed version of the magnitude spectrum.. The magnitude spectrum (processed if required) and the phase spectrum are combined to derive a frequency domain output, which is transformed to the time domain.

本发明提供了一种音频信号处理系统,其中基于多径干扰的测量来处理频域音频信号的幅度谱。 该处理使得幅度谱在多路径干扰期间保持近似固定,例如通过用幅度谱的时间平滑版本替换幅度谱。幅度谱(如果需要,处理)和相位谱被组合以导出频域输出 ,它被转换到时域。
