Personally, I record at 48, and I can tell some difference. Its not to where you could give me 2 different recordings and I could point out which was 48 and which is 44.1. Lots of people will come back with the "there's no difference". And for them this is probably true. You would be hard pressed though to find a studio which works on a digital format who records at less than 48K. The daw you bought will handle 48K with no problem. I have 24-48 projects with 80 tracks, and at least 40 plugins running, and the ADK don't even start to get sluggish. As for converting your projects, I'm not the one to answer that. It depends on a lot of things, such as some of your sonar settings.

FOr those who do record at 48, is it a noticable enough of an improvement to make it worth switching? If you wanted to experiment and record something at 48, besides changing the sample rate on your audio interface, and going in to the options menu and audio in sonar, is there anything else you would need to do to make this switch? Also, how would you convert from an existing project that was recorded at 44.1 to 48? Thanks fro your help, Brian
