I use Audacity to record audio lectures. This has worked fine for years. Just the other day, I recorded a lecture and everything went fine. Today, I made a new one and it has terrible, loud static throughout. I guess I should have shaved it before I did noise reduction because I wonder if that is the cause. I’ve never heard a lecture I recorded with so much static. There are spots withouit it, but most of the lecture has it. I tried to undo the noise reduction, but I don’t know that it helped. Now, I have terrible static throughout. What might have caused this? Is there a way to remove it, given that it is almost everywhere, not merely on blank spots of the recording? This has never happened to me. Thanks.
How and with what? We have to build your system in our imaginations to figure out what could be wrong.
Pretend I’m going to go shopping for your computer, recording interfaces, and microphones.
Did you recently do a computer or an Audacity update? Do you use the computer for other sound jobs such as Skype, Zoom, or Meetings?

Thanks for your response. I recently updated Audacity. I use a Sampson Q9U microphone on a Windows 10 desktop computer. The mic is on a boom arm. It might have beena llittle closer to me than usual, but I don’t think so. I did most of my recording with a much older mic, but I can’t tell you what it was because I don’t know. I’ve recorded using my current mic and not had this problem. The only thing that is different is that I tried noise reduction following a video I saw on Youtube.

So you are the performer. Cool.
Do you remember which Audacity version you changed to? Do you still have the installer for the Audacity version before this one?
Select 20 seconds or less with speech and silences that all have noise. Export it as WAV (Microsoft). It should come out as less than 4MB. Post it. The thick bar with up arrow is the icon for posting sound.
Sometimes we can listen to the damage and recognize it.
Just for grins and giggles. Do another short performance and make sure it still does it.

I am on Audaciy 3.7.5. I just tried about 1 min and 15 seconds. I did not do noise reduction and the recording sounds fine. I’ll know in the future that what ever tool I se to remove excess noise, Audacity isn’t it. Thanks.
Without changing anything else in your setup, try recording your work using Ocenaudio instead of Audacity. It’s also free and easy to use. Let us know if you fare any better with that.
