I'm on windows 7, using a POD GX with POD farm 2, and Audacity to record my guitar. I just noticed that on the recordings I make, there is some kind of noise when a note is being played. This is especially apparent when the note being played is low. I tried another guitar and the problem was the same. Here is a recording of me playing the open strings so you can hear what I'm talking about : https://soundcloud.com/professor-jones/noise If you have an idea of what it is and how to get rid of it, that would help a lot. Thanks !
