Topic: 24/44.1 question

[Gordon]

so buff sent me his and martins cowboy junkies masters from nashville.  they are 24/44.  gonna seed the 16 bit and keep the 24 if anyone wants it.  anyway so here is my question.  I use Audio DVD Creator for 24 bit shows but the files have to be either 48k or 96k.  should I up sample myself in wavelab to 48?  or let Audio DVD Creator do it?  I would think it would be best to do it in wavelab.  should I do this for personal use only?  or since people would have to do it to burn a dvda anyway, keep the 24/48 files on hand?


edit:

I know Audio DVD Creator doesn't create a true dvd-a.  do other programs allow you to make them with 44.1 files??  or do they all up sample?

Gordon, if I were you I would burn a true DVD-Audio disk. As you probably know, Audio DVD Creator does not make Audio DVDs but Video DVDs with 24-bit audio tracks.  These just work with 24/48 or 24/96 so you have to upsample. With DVD-A you just could burn the files "as is" and so archive them.
Anyway your question is about letting Audio DVD Creator upsample alone and drop the original 24/44.1 file after that. Well, I wouldn't, because you have no reliable info as to the quality of the upsampling algorithm used by that soft. I tried a comp and the computing time it took to upsample is rather short, which is somewhat unsettling. My wild guess is that upsampling is done in the 24-bit realm, yet for a clean job to be done, it should perform it in the 32-bit realm.
If I really had to burn a DVD-V, what I would do is I'd use a good app like SF8, Audition 2 or even Audacity, convert to 32-bit depth cleanly, upsample, then dither down to 24bits before burning.

use wl 5 and upsample

Pretty sure you mean 24/48.

I don't think Gordon necessarily wants to create a DVD-A disc--I know I don't have a player for that format, so it's DVD-V only for me.  He can just archive the 24/44.1 file to a DVD data disc if there's a need to keep the original file.  Otherwise, I agree--use the best program you can for the upsampling, and the authoring software is likely not to be it.  If he's willing to convert it to 32 bits first and dither back to 24 afterwards, all the better.

Sure it was a typo...thanks, corrected!
