Ideally, the microphone should be right on top of the source, with the gain no higher than necessary to get peaks around -3dB. But, boosting the gain amplifies everything, including background sounds and even the internal electrical noise of the amplifier. The further a microphone is away from the source, the more you have to amplify the mic's input signal to get to a usable level. Get the desired signal as loud as possible (without clipping) into the microphone. This allows you to reduce the gain, which will also reduce the low-level noise. Be sure to download the LAME encoder located there as well, which allows export to the familiar.
