Abstract
A method for graphically displaying audio data within a computer system is disclosed. A frame size is first selected for an audio data file and the audio data file is divided into a multiple number of frames. Except for the last frame, each frame contains a substantially equal number of audio data samples. Then a multiple of variables is initialized. For each frame, a first data value, a high data value, a low data value, and a last data value are selected. Each of these four data values is stored in the appropriate variable. The data selection process continues until the last frame of the data file is reached. Finally, a line connecting all the selected data value points for each frame is displayed on a graphic display.
