Abstract
An image and an associated audio segment are recorded on a film negative. The information on the film negative can be printed as encoded sound data on photographic paper or the like. For displaying, the sound data is scanned, decoded to create an audio segment data stream, and the data stream is played, typically by a computer while a monitor displays the image at the same time. More realistic sound playback is achieved by recording audio segments with plural microphones and playing back the audio segments recorded by the microphones from one or more of the sources based on a user-selected area of interest on the corresponding visual image.
