Right this is my second attempt of getting help hopefully someone can help me. I have a Samson CO1U mic which is basically a USB condenser mic. Im recording on Sonar LE/ Audacity and still the same problem i get this really annoying hum which seems to take over the whole thing, seconds there is a poping/vibration noise when ever i record anything. Please someone help with this so far in four days i've got nowere and im just losing my mind over it. So help anyone, oh and jargen free hopefully im new to all this recording stuff.
