As I wrote in another thread:

From the DVD FAQ:
Quote:
Dolby Digital is multi-channel digital audio, using lossy AC-3 coding technology from PCM source with a sample rate of 48 kHz at up to 24 bits. The bitrate is 64 kbps to 448 kbps, with 384 or 448 being the normal rate for 5.1 channels and 192 being the typical rate for stereo (with or without surround encoding).
Source: The DVD FAQ - Audio details of DVD-Video

Your question in thread title is also invalid. What is 192kHz 48kHz?

So only use 48 kHz for the audio either at 16 or 24 bits.
I would use 192 kbps for stereo and 384 for 5.1 surround.

I doubt you have the recording and mixing equipment to really
utilize 24 bits or anything above 48 kHz or 24 bits anyway.

Keep in mind that a lot of people cannot hear the difference or
have a good enough set to be able to hear the difference. Just
so you know.

And lastly what you are asking is NOT supported by the DVD
format and a good authoring package will not accept such a
AC3 stream either.

There are enough DVD compatability problems out there without
people breaking additional "rules". They are there for a good
reason: compatability.

Let's keep our information in as little threads as possible so if
you feel the need to continue this discussion please do so in
this thread: http://www.dvinfo.net/conf/showthrea...threadid=28214

Thank you.

i understand the compatibility issues i suppose but if that is so then why does vegas have 640k DD setting and under project properties the audio tab gives you 192kHz-24-bit.

PS i have the m-audio rev 7.1 which does record 24-bit analog in. mixing can be done in computer via software.

Your m-audio might do 24-bit, but that does not automatically
also say you have 24 bits to begin with. You must have good
enough mics etc. etc. as far as I understand it.

Anyways, the options are there because the Dolby Digital
encoder supports it. I guess for other applications and flexability
for the future.

For example: I don't know if a HDTV broadcast signal can allow
for an AC3 stream and if so at what rates.

You can also record an AC3 *audio cd* with as high as you want
it to go and I assume most receivers will play it back.

It is just to not limit you for any near-future things you might
want to do.

The DVD format just has boundaries in which you must work. Sorry.
