Re: Backing up DVD-Audio

No, but I plan to write one if all goes well. I will have to see if my Fleetwood Mac disk is watermarked, and if not write one guide for that. I will wait untill dvda-author supports 6ch WAV to write one regarding copying of watermarked DVD-As. Unless anybody knows of any 6ch WAV > DVD-A software around. In which case please post it! As I am not aware of any non-commercial MLP encoder it would have to be resampled from 96/24 to 48/24 to compensate for it being uncompressed (MLP 96/24 is 1/2 WAV size, as is 48/24 WAV half 96/24 WAV size, so 96/24 MLP is *roughly* 48/24 uncompressed WAV size). Even if you where to have a DVD5 and burn the uncompressed 96/24 WAV to a DVD9 DL disc to allow it to fit you would still have the problem that 94/24 WAV is around 13MB/s, way above max DVD bitrate of around 10MB/s. Also as MLP varies and is not exactly half you may not get it to fit anyway, depending if MLP compressed over 50% Therefore the only option I see is to resample to 48kHz. I could allways do a guide on how to convert the watermarked DVD-A to 5.1 44.1kHz DTS CD audio discs however, I don't know how much other people would want that, but I would certainly find it very useful.

From what I have read over at doom9 the 24-bit is what most people can here the improvment on, as it is still debated if people can here much above 48kHz. I struggle to here the difference between 44.1kHz 48kHz 16bit audio. Maybe it is because I am young, I read somewhere that younger people have less sensitive hearing, if there is any truth in this I do not know.
