I am a little ignorant of DVD audio standards, and could use some tips about pushing the envelope.
Basically, I want to author a DVD with from 4 to 6 channels of uncompressed sound - with the original sound source being a CD. As I understand things, the DVD standard permits WAV sound, provided it has been upconverted from 44.1 to 48 kHz. Where I start to get a little hazy is whether anything more than stereo is likely to cause problems. I can put up with playback on a PC rather than on a stand-alone DVD player, if that makes any difference. In fact, I can put up with not necessarily burning a disc, and simply using the hard drive.
Why am I trying to do this? Well, it’s an experiment in using software to mimic active bi or tri-amping, if that means anything to you. The concept here is that some signal processing is applied to a CD track so that the high frequencies go to one file, the lows to another, etc. These individual stereo tracks are then all played back in synchronisation through separate amplifiers.
The advantage of going the surround-sound route is that it conveniently solves the playback synchronisation problems that would otherwise have to be overcome. The downside is that I am not totally sure I can do all this with uncompressed audio, and this is where I could use some advice. A related question is whether I can do this in DVD-V or whether it has to be DVD-A? Alternatively, I suspect I would have to start looking at pro audio mixing and recording tools, probably in combination with some specialised hardware like multi-channel soundcards.
