Thanks all for the responses. I can see where you might want to lose the original tracks, BTW, and yeah, recording with a mic from ‘X’ distance produces latency like you say. I guess overall I worry about an overdub, where the porential exists to destroy the groove. In my case, I am recording the bass guitar tracks first and the drummer is layin down on top of that. So it would be great to know that my track sliding is on target.
Sliding the track around is really interesting, BTW. There is a point, for example, in my senario at 2.9 ms, where I reamp the track and set the slider at -10 ms. The cymbal highs are gone and the bass tone is fat super fat - and yet the clarity of the vocals is still there. Really weird to hear this, and there are no ‘phasing’ effect to the audio. But if I go to -9.5, then the phasing effect comes on again, notably from the cymbals. It might turn out that this recording, B.B King Live at Cook County Jail/Every Day I have the Blues, used some processing that is giving the recording this phasing character to begin with, eh, I just grabbed it to try.
I need to try something more simple. Thanks again.
