While doing some pratice recordings, I think I found one mistake I was making under the preference tab. I did not have the AT2020 mic checked off, it was on a default setting. I also checked off WaveRT at 20 milliseconds without the exclusive mode, the latency was not all that bad, but I'll try it in the future. I also found the AT2020 mic levels in the sound card and adjusted it to a low level of 30%. I think once the AT2020 mic is checked off in the preference tab you can adjust the mic level at the track level without going to the sound card when in the recording mode, I could be wrong.
My question is when you arm the track for recording under the pull down tab there are three extra boxes you can check off, I left these unchecked. One says External Mic IDT Definition Audio CODEC, Integral Mic Arroy IDT High definition Audio CODEC and the other Stereo Mix High Definition Audio CODEC. Should I have checked off any of those boxes, they also have boxes for Stereo, left and right channels? I'm confused as to what these are ,the pratice recordings seem to be okay without distortion at the lower levels.
