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.
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.
