This goes along with the topic about the size of files. I get some of it, but what I'm wondering about now, is this: 1. On the Edirol (probably other recorders too) you can go the the 'Recorder Setup' and choose what number bps to use (128, 160, 192, 224 etc.) So if you have it set to say, 192, then when you save it to your computer with an editing program, you are asked again what number to use. Do you think that using different numbers in these two applications screws up the sound quality? I never noticed this before, but I use different numbers. 2. Sample rate - KHz: Not sure what that is, but you get two choices: 44.1 and 48.0 Does it matter?
