Hi all, As some one who is fairly new to computer based recording in general, but slowly getting my head round it all I wonder if someone could take the time out to explain to me what the actual (audible) difference between these three settings are. As far as I have gathered the higher the bit, the wider the frequency range? Is that correct. Also, what does "float" mean? (as in 32 bit "float"). I hear that recording in "24 bit" and dithering down to "16 bit" for cd is higher quality than just doing the whole thing in 16 bit. What about doing it in "32 bit float" and dithering from there. (these seem to be the three settings available to me in Logic Plat 6). And what does that really mean "higher quality" - can that be explained in a tangible way? How do these different settings then affect your CPU and I/O loads? Thanks for your time, John James www.johnjamesmusic.co.uk
