Weird sound on playback

Hi

I have recentky started voice over practice. Whewn I record a script and play it back I have had 2 things happen
There is feedback(a hum) on teh feedback or I sound like I am in a bathroom.

The latter is most recent as I updated my driver and reinstalled Audacity.
Can anyone advise how I can prevent these from re occurring? I have had no problem till teh last week

Thank you
Regards
Simon

Please give us the Audacity version and Windows numbers from the pink band above.

Installing Audacity doesn’t reset audacity. When you install, Audacity should ask you if you want to reset preferences and settings. Say yes.

Post a sample of the problem. You can use the AudioBook test format. It’s pretty universal.

Which microphone are you using are are you recording at the right level? You should be seeing the Audacity sound meters peak into -6 and the blue wave tops should be about 50%.

If you record at too low a volume, the natural hum in the system may take over.
