In Reply to: DVD+ audio creator 24/96 on dvd video easy posted by niconico on April 15, 2004 at 00:07:50:
I am very keen to 24/96'ify some of my CDs when I get a DVD-burner in a week or so. Exciting!Has anyone used this software yet for upsampling?
Cheers,
Paul.

I've tried it.
The user interface is terrible but it works.
The demo allows you to create a disc with 2*4 tracks maximum.I didn't use the DVD+AUDIO upsampling algorithms, but had Wavelab upsample some 44.1/16 tracks to 96/24.
DVD+AUDIO just passes these 96/24 files through and authors them.Don't ask me if I could hear anything on my el cheapo DVD player, I just wanted to check wether it's feasable to write your own 96/24 tracks to DVD-Video.
BTW, not many software authoring packages seem to like/support upsampled LPCM files.
Hi Paul,Yes I tried, the tool is working fine, I created DVD's (24/96) from some of my favourite CD's. However in my TacT system (which works internally at 48bits/96khz and thus does its own resolution enhancement) I could not hear any difference with the original CD. I guess the result is system dependant as I've read comments from several other users who were very happy with the improvement they were getting in their systems.
Note that a side effect of the process is a slightly reduced volume level which makes A/B comparison not really easy.
As it is not expensive, it is surely worth a try.
look at the previous threads on this product, it's been discussed and there's a significant issue with the processing involved to upsample audio files (it's been discussed on another forum (hydrogen?), with charts and everything). The software introduces significant changes to the soundfiles...If you want to author redbook to DVD, better use a good audio software for upsampling to 48 or 96k and a decent authoring / burning package...
or better still, write in native resolution to DVD-Audio.Best
I've read the discussion on Hydrogen and... yes it introduces significant changes in the soundfile. My purpose testing this tool was precisely to check whether the sound was improved due to this processing. They claim that the main improvement is due to the resolution enhancement algorithm (16 to 24 bits) and not to the upsampling to 96khz. My conclusion was that "in my system" the only thing I could hear was the minimal difference in volume level! I am not going further in this direction.As such I am not interested in storing my CD's on DVD's. I am actually more interested in storing my CD's on a PC server. In this respect I am testing the Squeezebox www.slimdevices.com. Going thru a reclocking system (Apogee Big Ben), the sound is excellent. That's a winner...
A winner?
No support for 100 MBit/s Ethernet (or 802.11g for you WaveLAN guys), maximum 48 kHz on S/P-DIF? So there will be no chance to playback SACD and DVD-Audio or DAD Stereo content. Very limited product.
Well... it supports the vast majority of all audio production... i.e. CD's!I have hundreds of CD's and only a few DVD's or SACD's. I am still not convinced that any of these formats will survive. And on the other hand CD's can sound excellent with the right equipment and recording (mind you I have some CD's that sound better than some SACD's).
It is their second generation product, I am sure that if the high-rez formats take off they will offer new products. In the meantime, I can stream all my CD's (uncompressed) whithout any problem on 802.11b.
the price is pretty cool also (they could call it squeeze bucks, hehe), wonder how those wireless thingies can handle audio streams (no cables issues, I guess :)Looking at all those new devices, I feel like I'm "old school" with my PC audio server, soundcard and cables :)

I have a quite good wireless signal between my wireless router and the squeezebox, I can pass uncompressed WAV at 16/44 without any problems. I made several test comparing my DVD transport to the squeezebox (both going thru the Apogee Big Ben reclocking device) and I cannot distinguish them in A/B tests. There are still some minor software issues but the software developments are very fast.
With all the steps the audio signal goes through in this process, it's no wonder that a reclocker is almost necessary for great audio (if not, you might as well just listen to mp3's). However, it's a weird technoworld where we spend $199 to provide 95% of the path, and then put it into a $1400 reclocker. Have you a/b'd without the Big Ben? Do you have the Big ben for other reasons, as well? Are there decent reclockers that are more in $line$ with the rest of the setup? I would think the P1A's and older Alchemy's of the world might work here?
Thx,
Ted_B
