PC Software converts 16/44 to 24/96 format

Just read an article about this on stereophile.com. I thought it would interest several of you. I have not tested it yet, but I certainly intend to soon. basically it allows you to convert 2-channel wav files to up to 24-bit/96khz format. It performs the necessary upsampling and word-length conversion and saves it to a file. This is the url: http://www.eximius.nl/dvdaudio.php There is no built-in burner support. You can use your normal burner software to write the files to DVDR media.
Will this actually give you better sound? Or is this the 2004 equivalent of "Stereo Re-Processing"? If the sound quality is not there to begin with, I can't see how adding random or spurious or even calculated information will help.
P.S. I was not referring to 24/96khz format, but rather the change from 16/44khz to the better format. To me that would be like taking cassettes and putting them on reel to reel, but thru a filter that would make it 'seem' more musical.
To the best of my knowledge wav files are not compressed in any way. Thus if you had a sound card that was higher than 16/44 you could then convert the better format and save that information. I'm really a novice in this area--but I've considered this for some of my LPs. I would like to know if I'm right about the wav files and how I could tell what the true bit depth and sample rate is.
My guess is that it will attempt to lower the noise floor and increase the dynamic range while at the same time interpolating the data in the upsampling process. I do not expect it to sound like DVD-Audio. The app does not require a soundcard. It isn't playing the file, just using the CPU to alter the amount of data. I still have not had an opportunity to do a listening comparison.
It looks like it's a software upsampler with a word length interpolator. It may improve the sound of redbook data streams, but it won't bring them to 96kHz/24 bit quality. WAV files can be any number of different sample rates and word lengths as determined by the software and hardware used to generate them. Most modern software allows for rates up to 192kHz at 32 bits and most hardware will go up to 96kHz at 24 bits. The A/D converter is the key determinate of quality.
