SPDemo is an assisting tool for teaching speech & audio processing techniques. It is a tool built with modular and flexible approach in mind. The result is an advanced product offering a variety of unique capabilities.Using SPDemo one can select from a variety of speech & audio processing techniques and parameters in a straightforward and simple way. The results of this processing are shown both numerically and graphically, in order to ease the analysis of the data. The purpose of SPDemo is to enable experimentation with different audio and speech processing algorithms without actually implementing them. For this reason, both ease of use and simplicity have been a main concern. The user can examine each technique with different parameters and can also examine final as well as intermediate results interactively. In addition, the application contains a short explanation of every algorithm. All this and much more helps in gaining insight on how the algorithms work and what are the effects of changing their parameters.
