This a GUI that manages DSP analysis functions for wav-files (e.g., speech signals). Two functions (plotps.m and spect.m) are included for starters. You may write your own functions and integrate that into the GUI without much hassle (see instruction

数字信号处理器（DSP）作为一种可编程专用芯片，是数字信号处理理论实用化过程的重要技术工具，在语音处理、图像处理等技术领域得到了广泛的应用。但对于算法设计人员来讲，利用汇编语言或C 语言进行DSP 功能开发，具有周期长、效率低的缺点，不利于算法验证和产品的快速开发.C6000是高性能数字信号处理器。-Digital signal processor ( DSP ) as a programmable chip, digital signal processing theory practical

一种基于DSP的快速傅里叶变化FFT算法的程序，是声学、语音、电信号处理的重要工具。-A DSP based fast Fourier change program FFT algorithm, is an important tool of acoustics, speech, and signal processing.
