This a GUI that manages DSP analysis functions for wav-files [especially 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 instructions in the accompanying Readme.txt file]. Additional features like the snipper lets you trim the time series and save it as a separate wav-file. The GUI is a great tool for instructors in a DSP course and DSP researchers alike!-This is a GUI that manages DSP analysis functions for wav-files [especially speech signals].
