Coming back to this thread, if you don't mind, I'm still uncertain about exactly what is happening in Waveburner. As I described above, I master songs in Logic and retain 24-bit for the stereo bounces with no dithering (duh). I then import the songs into Waveburner for CD compilation. Out of curiosity, I turned off dithering in Waveburner's Preferences (Bounce tab) and then executed a CD burn from the Waveview page (not p;receded by a bounce). According to your description above about Waveburner behavior, the files should have automatically been reduced to 16 bits. Typically, when I burn to disc in Waveburner (hit the Burn button) from the Waveview page (prior to making a bounce of the entire project), if a dithering algorithm was selected, I see a scroll bar for bouncing, even though I didn't select Bounce, prior to initiation of the CD burn. But in this case, with dithering turned off, the burn from the Waveview page commenced immediately. So I fully expected that the CD would contain 16-bit files that had not undergone dithering, and so would contain artifacts. But when I gave it the 'test drive' in my car CD player, it sounded fine. Maybe I'm not listening well enough, but shouldn't there be noticeable artifacts?
