Noise could be background hum, clicks and pops and, generally, any unwanted sound.  However, Mixcraft's noise reduction works best on constant noises such as fans, air conditioners or anything constant throughout the recording.

Click on the audio clip that you would like to remove the noise from.  Click on the Sound tab on the bottom.  Click on the "Noise Reduction" control and select a value up to 100%.

Once you have selected an amount, Mixcraft will attempt to automatically find a good noise sample.  Mixcraft shows the noise section by two controls called "Noise Start" and "Noise End".

The above image shows an example of a good noise sample.  The noise is determined by the audio section between the "Noise Start" and "Noise End" controls.  You can edit the noise sample by clicking and dragging the "Noise Start" or "Noise End" controls.  If you want the software to automatically locate the next best noise print, click "Next Noise>>".  This instructs Mixcraft to look for the next best noise sample based on what it thinks could be noise.  Only you know what noise is, though, so you may need to adjust it manually.

The best candidate for noise reduction is a sound that has a snippet of the noise by itself.  For example, if you had an air conditioner in the background and you started recording, you should have one second of the air conditioner by itself.  Then choose the section of audio that is just air conditioner for your noise sample. If you don't have a good sample of the noise, you could try and re-record the noise by itself and then Merge the clips together.
