The advice I often see here and elsewhere is that, if my other digital audio programs run fine on a particular computer, BIAB should, too. I've written elsewhere that I don't think this advice applies as well now. Two years ago, when the speed of BIAB's regenerating was remarkably shortened, it increased the need for more cores and a faster processor. I have read the minimum requirements and, while they work, you may not be happy with it. You mention distortion and RealTracks so you are aware this can be a challenge. There are settings within BIAB to lessen the load, and threads here with these tips. One is that the more you convert RealTracks to audio, the less stress on your computer.

There is more to it. There is always more. But if you are buying, put your money into this order: CPU, RAM, SSD storage for the RealTracks. Graphics are not important for BIAB (now, at least).
