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.

A multimedia system includes a multimedia device control program having a plurality of application program selectable controls for controlling operation of a like plurality of different classes of multimedia devices. Each class has a different set of controllable device functions or attributes. In response to selection of a class by an application program, a unique control panel is created in a user interface for controlling operation of a device. The selected control performs all of the processing actions necessary to control the device in response to user selections on the interface, without involvement of the application program in such actions. The multimedia control program includes a plurality of panel templates from which control panels are created in a control screen. Each panel has a plurality of controllers that can manipulated by a user to control a corresponding function of a multimedia device. The templates provide a consistent interfaces having a common look and feel. The multimedia control program also includes a plurality of class control programs one or more of which are selected by an application program to be attached to a like number of multimedia devices for controlling operation of the devices in response to user selections on the user interface, thereby relieving the application program of performing the necessary control functions.
