Ports in computers are used mainly for two reasons : Device control & communication. Parallel ports are mainly meant for connecting the printer to the PC. The purpose of this paper is to design and analayze a sound generator for wave file format by the use of the data and command port of the parallel printer port , the parallel printer port is being programmed to transmit the data from the wave file to the designed device. Some of integrated circuits used in abundance in most electronic applications have been selected in order to achieve its purpose, that all the constituencies used are electronic circuits and logical circuits dependent upon in the design of this sound generator. A digital to analog converter is being used in order to transfer the data from the digital to analog to be heard by the human ear. A program written in Visual Basic language to extract the data from the wave file and to activate the designed device.
