Hello, thank you so much for helping. Let me just put out, I am an audio noob. Now lets begin with the weirdest microphone story ever heard. First, let me list the equipment: 1. Audio Technica ATR Condenser Microphone 2. 2010 Apple IMac Desktop 3. Audacity Now the main problem I have is a pop sound that would happened randomly, and a buzz that would happen throughout the audio. I went on other forum to ask for help, and the weirdest thing happened. When I changed the sample rate from 44100 to 48000, the buzzing and pops lowered dramatically. Instead of making the audio unusable, the pop thing would only happen sometimes, and the buzz was a lot more quiet. To fix the pops, I just plug the USB into a different socket each time until it works. The buzzing changes in volume and intensity with different plugs. It is completely random, so I just plug USB into a port that works at that time. Now I have a Rossetta Stone headset microphone that works perfectly. No buzzing or hissing. I have a unpowered and powered USB hub, and both don't work for the Audio Technica. I really just want my microphone to work. Please help me, and the person who solves this will be my everlasting master and hero. Thank you.
