Nope. > if not, then why bother? I'd never heard any music with quantization/rate better than 16-bit/44.1kHz. I didn't intend to answer the question of which format is better nor for which application. I was just curious as to what it sounds like. Now I have a subjective sense of what it sounds like. I can sort of remember what 2" 24 track audio sounds like, but that was in a much better room. I wouldn't try to prove it, but I think that analog format sounded better to me that 16/44.1. Now I've gone out on a limb. For my own purposes, I'll be going with 24-bit, because it makes sense from the mastering point of view, and because my hardware should do that. I'll find out how well it works when I try, and I could try some objective, measurement based tests to verify this. I'm going to also go with 44.1kHz because I'm recording against material recorded by my bass player and my guitar player, and they run at 44.1kHz. I believe ardour wants all of it's data in the same format for each project, though projects can differ from each other.
