Annotation

There is a broad range of sound players, e.g. Windows Media Player. But in a style of Microsoft this project has no documentation. For other similar projects it is typical to have open source and to have no project documentation.

The goal of this work is to create a simple sound player. Its main features contain:

• building up the control system based on the automaton approach;
• creating an open project documentation.

Advantages of automaton approach consist of following points. Firstly, automaton idea can increase the centralization of logic in source code. Secondly, source is isomorphous to transition graph, which is a base for creating a source code. Added to this, the projection itself is a separate stage, which is the most important part of creation of a program.

The project is made according to The Motion of Open Project Documentation. The attention is focused on the formalization of building the control part of the program. Project is made in C++ using MFC library in Microsoft Visual C++ 6.0.

To get a sound from the player there must be a folder mus in the directory of a program with audio wav files , named by numbers by order beginning with 1 (1.wav. 2.wav, etc).
