Hello,
I have been reading about the new WaveLab 5 and it gave me an idea but before I go shelling out that kind of money I want to know if it will work for what I want it to do.
I have a sizable CD collection, however now my preference is DVD-A and SACD. So I was thinking that I could use WaveLab 5 to upconvert my CD’s to 96 or even 192khz and burn them as DVD-A’s. I figure I could put several upconverted CD’s on to one DVD thus compact my collection while I was at it.
Would I be able to do this easily with WaveLab 5? If so would there be any audible difference in upconversion or is trying to upconvert audio a waste of time and disc space?

Hi Socio,First, you can transfer all your CDs, LPs, SACDs, laserdiscs etc to DVD, you only have to chose between DVD-V and DVD-A for your authoring format. As explained in a post below, the fastest and most convenient option is DVD-Audio, because you do not have to resample your files at all if you don't want to, and should be able to store an average of 8 CDs per disc.
I do not have Wavelab 5, so I cannot comment on the added functionality of the software over discWelder, but I suspect it will have better graphical menus and the ability to convert / edit your files from within the same application. This may prove useful if you want to edit and normalize your CDs for long play programs.
Second, Re: upsampling your files. You simply don't have to resample anything in DVD-Audio, redbook PCM is a native resolution in the specs. I have made many attempts at upsampling redbook CDs to 24/96 and 24/192, and to be honest, unless you do non-linear operations or mixing, I am not sure it's worth the extra time and effort (and disc space :)
You do need increased bit depth for added precision if you plan to do any editing, normalizing or compression on your files. You will be able to dither to 16 bits in the end if you need disc space, but you won't have to. Higher sampling rates will not change anything in that respect.
One area to look into is the CD vs. DVD sampling rates. Some people have suggested that DVD-based players handle the 48k "family" of sampling rates better than redbook. I personally upsampled many CDs to 48k to make them available for either DVD-V or DVD-A, and found that 48k had good results. Other inmates have made comments that they thought the sound was degraded after conversion from 44.1k to 48k. It really depends on your player, and the availability of good upsampling software (Adobe Audition has good resampling functions).
You may also want to compare the results of software-upsampled CDs with upsampling directly on the player, because an increasing number of DVD-Audio models (Panasonic) have pre-set upsampling converters that, maybe, do exactly what you want for 150$.
I have found that my old Technics A10 can upsample 44.1 and 48k to 24/192, and sometimes the results are better than when I do the upsampling myself on my PC...
I hope this helps.

Its a waste of time as far as increasing resolution. However, you could prolly save space in your collection by copying a couple CD's at once onto a single DVD. Better yet, use lossless compression like FLAC and you can burn even more CD's (data) onto a single DVD..........They are going to be releasing the next gen of DVD and DVD burners soon which will hold much more than the current DVD. I can't recall if these new DVDs are double sided or just have more layers.......... I think I read this news on CNN webpage earlier this week. Check it out if interested.

also known as DVD9 will be out this year for PC-based DVD burners, see link for some background info. We should be seeing "DL" or something similar added to DVD burners and discs pretty soon.As for storing CDs on a DVD, your comment on compressing more data on a disc only makes sense if you plan to play your DVDs on your computer, because a disc like that won't play in a set-top player. With a DVD-Audio, you can currently store 7 hours of CD music in native resolution, without any conversion... in my experience that's an average of 8 commercial CDs per disc. If you record 24/96, like for example SACDs, you can only store 2.5 hours of music, but you can expect those figures to double with the introduction of DL discs.

the upconversion is just a scheme for gentler and cheaper filtering in D/A and A/D conversions and anti-aliasing, but thats already done on the CD and playback side....it adds NO significant data whatsoever and so cant be better unless you want to do further filtering....THe higher amount of memory (at higher freq and bit #) and time required to burn precludes any advantages i know of...it might be useful if you are working with analog sources such as LPs, etc.
Well it sounds like a bad idea now, no enhancement after upconversion and the extra memory used for 24/96 would not allow me to put as much material on the DVD's as I had hoped.I suppose I could take a single CD and try to re-mix it in WaveLab to 5.1 surround then burn as a DVD-A but it would probably sound awful.
I guess for now I will have to keep replacing what CD's I can with DVD-A and SACD's as they are released.
is to use Adobe Audition(/Cooledit pro) and Discwelder Bronze.Sum LR into a mono channel for the center and try a nice reverb to create rear channels from the l/r fronts.
Decents results can be achieved of you keep the settings subtle.Of course you can only create 24 bit 44.1 or 48 kHz'surround' files.
