High pitched noise when turning mic on + buzzing noise

I’m recording with audacity, and usually when speaking i have a normal voice, volume wise. I tried using the Microphone Enhancer in the default volume options in Windows 7, but the more DB i add (10/20/30) the more background noise i get. With +20 or +30 the volume is at a comfortable level, but the background noise also goes up. I’ve tried editing it out, but that takes a long time to do, which is a pain in the ass to do, for something that should work most of the time. Editing it out and amplifying my voice and using noise removal mulitple times also makes it sound very strange. I already put the soft cushion-y object on the microphone itself to reduce any background noise.

When i turn my mic on or off, i get a VERY high pitched noise and a loud crack, or some sort of click, which is especially annoying if you’re wearing headphones. When the microphone is off something produces another(?) high sound.

One last thing, under the sound tab, my microphone is marked as the primary device, 2 other devices are off, and a device called stereo mix is on, should i leave that one on?

The buzzing noise and the pitch just don’t go away, and it’s very annoying. I’m going through some kind of loop it would almost seem, I have a slight buzz with lower volumes, but i can barely hear myself. The higher i set the enhancer (+10/20/30) the worse the buzz becomes. And then there’s the high pitch that comes with turning the microphone on and off.

Enhanced Services are for video conferencing. You should turn that off right away. Stereo Mix is used to record internet audio and can destroy a straight musical recording. Select your actual microphone or soundcard for personal recording. That should take care of the whistling and feedback.

You can also select the ins and outs of your sound with the Audacity Toolbar.


You can get serous sound disturbances by turning off a microphone while it’s connected and turned up. A sound system expecting a tiny fraction of a volt of sound may suddenly get the full blast of 70 volt phantom power instead. Good way to blow your ears across the room.
