squeeling noise when recording voice.

post #1 of 4
Thread Starter 
Hello everyone,
So recently I tried recording my voice for a school project, I used audacity to record it but while recording I heard some weird squeeling noise.
Sounds like this: http://www65.zippyshare.com/v/80251528/file.html

It also does this when I unplug my MIC (As a matter of fact, ^ is recorded without a mic)

I'm stumped on what to do. I've tried messing with MIC boost, levels, etc, to no avail.

Any suggestions?

PS: The problem is not audacity. I tried camtasia, Sony Vegas, and other programs and all give the same noise.

Make sure all of your other audio inputs, such as line in, are muted.

Minimize CPU and GPU usage while recording; I can't download your file, but what you are hearing is likely switching noise from VRMs. The higher the load on the VRMs, the louder the noise will be.

Other than that, use something else to record it. The noise is likely a hardware problem.

You may be able to use the graphic analyzer in Audacity to see what frequency the squeal is and then turn down the equalizer on the same frequency to remove some of it.

I turned them all the inputs to 0 before, but actually muting them seems to have done the trick.
PS: you didn't have to download the file. You're able to just play it on zippy, that's why I chose that site so people don't accuse me for posting virusses, lol.

Thank you!

I thought it was fixed, but I can still hear it.
Or it may have fixed it for a while? But I can hear it again.
