When I record without making any noise, I can see the buzz appearing in the track as shown below:
So I recorded on another machine to test if it was the microphone. No problem there and it recorded crystal clear. Audacity had always worked fine before on both machines.
I have tried the following troubleshooting:
1. moved the microphone away from electronic devices.
2. tried adjusting volumes through the control panel audio and recording options (that makes the volume recording higher or lower but does not stop the buzzing...that simply gets louder and softer along with the same adjustments).
3. Tried other USB ports on the machine to see if it was a USB problem...no difference, same buzz.
I am open to troubleshooting of any type. Also looking for suggestions on proper grounding or "earthing." I have a lot of power strips and wonder if that may be the problem.
Thank you for any help.
