A distance between a cursor and an object displayed on a Web page or other image automatically controls a volume with which an audio file associated with the object is played. A user can thus explore a displayed image to discover audio files associated with different objects or portions of the displayed image. The audio files can provide instructions, data, music, sound effects, or almost any other form of audible sound desired. The designer and/or the user of the displayed image can set parameters that control how the audio files are played, such as the maximum distance of a cursor from an object to initiate play, the relative priority of the objects, and the maximum number of audio files that are simultaneously played.
