Importing 96kHz/24bits WAV files into Audio DVD Creator?

[neo_74]

Hi All, I'm still new at this so bare with me.......

This is what I want to do, does it seem logical?

01. Re-sample .Wavs to 96khz/24bits and then import them into Audio DVD Creator
http://www.audio-dvd-creator.com/

Is there any benefit to upsampling a .wav, or is this something that should of been done to the .wav when it was originally being created instead of the typical dvd 48KHz?

Am I correct in assuming that there will be no quality loss unless I convert the .Wavs to AC3?

Are there any restrictions as to what type of equipment 96khz/24bit .wavs play through?

Lastly can anyone recommend some simple software to do the resampling?

Thanks for your input & time..........

Resample from WHAT??? (8kHzADPCM, 22kHz mp3, 196kHz-32bit LPCM, 48kHz-16bit, SACD 2.8MHz...)
Makes a huge difference. Resampling from higher makes sense, resampling from lower won't help an already bad quality)

Quality loss: resampling always has -some- quality loss, although it can be minimal in the process itself. Just like resizing a picture.

I don't recommend 96/24 unless you ALREADY have a particular DVDPlayer that specifically and explicitly supports 96/24 WITHOUT downsampling available, because --with a few exceptions-- basically NO players support this. A few more will do 96/16 or 48/24. But you're still doing ok with just the standard 48/16, which just about ALL players support.
Unfortunately, just because it was allowed in the spec doesn't mean player manufacturers are willing to invest in it (especially if they don't think there's a market for that sort of thing).

If you really got to have 96/24, it probably makes more sense to get a DVD-Audio (or Universal) player. [EDIT: ...and burn as DVD-Audio, not DVD-Video]

You're not gonna gain anything by upsampling; it won't create information that wasn't there to begin with. In theory you are right, AC3 is a compressed format. It doesn't mean it won't sound good, but it won't be like the original.

The only reason for resampling a wav for an audio DVD is when you have it from a CD (44.1kHz/16bit), then your target is 48kHz/16 bit - just to make it compliant with DVD-Video. You wouldn't gain anything in quality by making it 96/24. While resampling, to keep the original quality it is a good idea to temporarily upconvert bit-depth to 32 or 64 bit (e.g. in SoundForge sound editor), then resample to 48khz and return to 16 bit. This trick minimizes rounding errors at intermediate calculations and is a must for music material. The widely used free utilities work in 16 bit and therefore are only suitable for film soundtracks.

Thanks for your feedback..........

Ok, now that I understand that upsampling is of no benefit to me will the following work?

01. Take my 44.1kHz/16bit .wavs and change bit-depth to 32 or 64 followed by a convert to 48kHz/16 bit in order to make it dvd compliant.

02. Now if I import these into DVD Audio Creator the program should only add the fancy track listing and menus without further conversion?

03. Otherwise can I just take my 48kHz/16 bit .wavs and put them into folders to be burnt to dvd?

Which is an easy free utility to change bit-depth? Possibly Belight?

Thanks again for your time.

01. Yes
02. Yes
03. Not really, as (if I get your meaning correct) a simple data DVD could have WAVs in Folders on it, but FEW DVD players explicitly support WAV playback.

Usually you have to author a DVD-video with these audio files using DVDLabPro or DVDArchitect (both have special option for audio-only tracks). Audio DVD Creator is easier to use for this but I don't know whether it re-encodes the already compliant files (you'd lose some quality in that case).
