The alogrithm employed in this toolbox for determining Lyapunov exponents is according to the algorithms proposed in [1] A. Wolf, J. B. Swift, H. L. Swinney, and J. A. Vastano "Determining Lyapunov Exponents from a Time Series," Physica D, Vol. 16, pp. 285-317, 1985. [2] J. P. Eckmann and D. Ruelle, "Ergodic Theory of Chaos and Strange Attractors," Rev. Mod. Phys., Vol. 57, pp. 617-656, 1 The algorithm given in [1] is used for first-order systems while the QR-based algorithm proposed in [2] is applied for higher order systems. by Steve W. K.

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). )
