Fractal Fanatic
For you veteran professional guys this is probably one of those "no duhh" type posts, but I did run into this as I've been 'optimizing' my modest little setup for pain free recording and re-amping.
I'm getting great quality dry and wet and re-amped recordings via ASIO4All using my AxeFXII's USB outputs, inputs and my Saffire DSP 24Pro in a pseudo aggregate device setup with PreSonus StudioOne (I am a really big fan of this DAW right now). Got everything routed so that I basically just have to change the input on the AxeFXII from front analog to USB and hit record. No pops, glitches, dropout, jitter and the levels are dead on.
So the problem...play the original wet track and the re-amped track and its a mess in terms of phasing issues.
Now the latest beta of ASIO4All does have something called latency compensation, but I can't figure out how to get it to work so I left it at default. Even if I was able to figure out how it worked exactly trying to get the timing down would be a frickin' headache. Doing it inside of the DAW was a big enough pain in the ass to be honest so I figured I'd give some quick pointers on how I figured it out finally. I'll try to cut to the chase here.
Phase inverting. That was the only way that I was able to adjust accurately. I tried a quick transient and got semi-close a few times, but even in a loop it's too short and you can get confused on which direction you need to go. So I figured that if I put the re-amped track 180 degrees out of phase and then adjust the track delay that once its right I'll get a null output or total cancellation. Seemed to work really well.
I'm at about -23.43ms which is a pretty significant amount on paper, but once you consider that it's going from disk out to USB through the AxeFXII to analog, through some A/D convertors, through firewire and then to disk it's not too bad...but more important there is a way to adapt to it built into the DAW. From what I understand this is a pretty standard feature in many DAW's.
Now there is something called pipeline inside of StudioOne that supposedly lets you measure the delay/latency of offboard gear, but the closest I managed to get it configured was a big fat feedback loop. The phase inverting thingy worked really well for me and it's saved in my re-amping template so I don't have to figure it out again.
