Using Windows 7
With Audacity, the Audio Host is set to “MME”; Output devise is set at “Speakers - High Definition Audio”; Input devise set at “Microphone - High Quality Audio” ; Input Channels set at “2 - Stereo Input Channels”.
The recording is working except there is a background noise.
How is that background noise removed. I have used several Effects without removing the background noise.
In advance, thanks.

Try the [u]Noise Removal[/u] effect. If the noise is bad you can get artifacts and “The cure can be worse than the disease”, but it’s usually worth a try. Make sure to get a Noise Profile, so that the filter knows the characteristics of your particular noise…
If you have a single-pitch noise such as AC line hum, a notch filter can be very effective. But other than line-hum, single-pitch noise is rare.
And, in some cases a high-pass or low-pass filter can be helpful, but it’s a rare case for the noise to occupy a different frequency band than the program material, so there is usually some damage to the good audio also.

If you are using the microphone built-into a laptop, don’t expect great quality. For best results, you need a “studio style” condenser mic, or a "performance mic (not a “computer mic”) and a USB audio interface with the proper XLR microphone input, or a “studio style” USB mic.
You’ll also need a nice quiet environment and good mic placement. Plus, something good-sounding to record.
