So, I have been working over the past couple of years intermittently trying to record both my guitar, and lately my voice, using my laptop and audio interfaces. I have always run into the same problem: background hiss and white noise. I have done this using Windows (XP, Vista, and now Windows 7 64-bit), as well as Cakewalk Music Creator and Reaper. I also have used two different audio interfaces. I just bought a Furman power conditioner and a Saffire 6 to try and mitigate the problems, and while they are not as bad, they are still there. First of all, I found I CANNOT record if my laptop is plugged in because of “blip/beep” noises it creates. So I run on battery. I also disable my Wifi card, turn off fluorescent lights, and turn my cell phone to airplane mode – I don’t know if maybe my speakers or internal audio card need to be disabled somehow also. Tonight I was using the Saffire as the only input and output, and that connects through the USB to my recently purchased Lenovo IdeaPad (laptop). So I've found a number of PARTIAL solutions so far, but not completely gotten rid of the issue. I'm running Windows 7 64-bit, running an Audix vocal mic with XLR on both ends into line 2 of the Saffire input. Reaper seems to be set up correctly to ASIO and recognizes the Saffire drivers. So with all that said, is there anything I’m missing? Do I need to create another ground and balance the signal like people on here who are having monitor issues, or do I need to look elsewhere? Thank you guys! I appreciate it. P.S. I am using a Monster Cable Standard 100 model XLR 25' cable - maybe I need a heavier duty (or shorter) one?
