[matlab] chxu DL : 1: 本程序用于测量增强语音与纯净语音的对数谱距离，用于语音增强。对数谱距离越小，表明增强语音与纯净语音越接近，增强语音质量越好；反之，则增强语音质量越差。-Calculates the average log-spectral distance between CLEAN and NOISY signals. Frames are 25ms long with 60 percent (15ms) overlap, hamming windowed. RS is the remove silence option (default: 0) if 1, the program uses a Voice Activity Detector to find non-speech frames and eliminates them from calculation of LSD. FS is the sampling frequency (Default 10KHz).
