It is fairly well known on this forum that the 1993 Definitive Collection laserdisc soundtrack comes the closest, since it was sourced directly from the 70mm printmaster. But because of numerous added sound effects (some of which are worthy additions, while others prove more distracting), it occasionally leaves the listener with the feeling that they are not hearing the film's "real" sound mix.

this may have been answered here or elsewhere but what about the audio of the widescreen edition: are they untouched and represent the original theatrical mixes?
