Hi! I'm working as a cinema projectionist and I know people who got everything setup in the projection booth in order to record sound from the analog optical soundtrack of a 35mm print. Would such an audio sample do in order to test out the "matrix-encoded audio" filter/feature of MPlayer? The audio sample would go trough the noise reduction filter (Dolby A/Format 04) in the Dolby Cinema Processor unit, but recorded before the channel separation filter. The recording device is an old CD audio recorder unit and the result would be similar to an ordinary audio CD. This would probably brake some copyright laws, but I think I could get permission or find a way around it.
I also know there exist some films shoot on video and mixed with stereo surround sound (low budget/ local film makers). If you choose to screen such a film from a computer instead of a video player this matrix decoding feature of MPlayer could turn out to be useful. On the other side, I'm not really sure there is a difference between the stereo sound from a VHS/DVD or a 35mm print of the same title (at least not all of them). It should be the same sound mixing, or why shouldn't it be? With different sound mixing the Dolby ProLogic technology wouldn't work. Or am I missing something? /Jesper _______________________________________________ MPlayer-DOCS mailing list [email protected] https://lists.mplayerhq.hu/mailman/listinfo/mplayer-docs
