DVD+Audio Creator

I tried the software. My interest is in upsampling-related claims mainly, because of this I've only created the VOB/IFO files on HDD, no (mini)DVD burned.There's no installer, the .exe can be started from anywhere (but it writes entries to registry). The default browser is used as GUI - it works and is quite easy to use. I let the software create 24/96 PCM DVD files from some songs in .wav format ripped from CD. The 24/96 LPCM audio in the resulting VOB/IFO can be extracted with vstripGui and LPCM24 (-> rarewares) to 24/96 wav - as I have done it with a Chesky DVD-V with 24/96 audio before. Everything as expected so far. I opened the 24/96.wav in a Hex editor to see if there's padding - nothing obvious visible (like every 3rd byte = 00). Then I opened it in CoolEditPro. For comparison I upsampled the original CD .wav file to 24/96 with CEP highest qualtiy settings as well. This is how the result looks like in frequency view: To save space one matching channel pasted to one image; the upper one is DVD+Audio Creator There's clearly visible the ringing near cutoff frequency and > 22kHz distortion added. Looking at the zoomed waveform there were no "evil" resampling technics visible like "nearest neighbour" or "linear interpolation" though. Besides this, the DVD+Audio version is amplified to a little bit lower volume, something like -1dB compared to the original. I don't see why this sub-optimal resampled version should sound better than the original. I wasn't able to hear any obvious differences (envy24ht based soundcard+Sennheiser headphones) and didn't want to spent time on ABXing - anyone interested can download the software and give it a try. Anyway, I've been looking for a cheap/free software that can create DVD-V with 24/96 audio for some time. As said before, it would be nice if DVD+Audio Creator accepted 24/96 PCM .wav as input.
