I recently discovered that any microphone I plug in generates the same background noise. Some helpful users on Superuser pointed me towards buying a USB soundcard/Preamp to elminate this, and I've also considered recording from my phone (sounds silly) as the phone doesn't seem to have the noise problem, but I'd require a few cables and adapters. My other ideas are buying a pocket recording with a mic in, or a Headphone to USB converter. Would any of these solutions I have come up with work?
