Just a quick survey question to try to get a handle on the possible
applications and market (if any) there would be for a digital Dolby SR
implementation, either in plug-in form or as hardware. For example,
didn't the old optical movie soundtracks use this for NR?
They still do. Maybe 75% of the movie screens in the country are showing
SR soundtracks. The other 25% is a mixture of digital formats and Academy
Mono.
All of the digital systems today use an SR optical soundtrack as a backup.
In the case of a Dolby Digital film, you will normally see it briefly fail
over to the SR track two or three times in the course of a feature film.
If the system is properly aligned, the failover is almost unnoticeable.
Note that of those 75%, a whole hell of them are actually showing SR
soundtracks decoded by Dolby A decoders. This is shameful.
