Selecting an audio voice; reduce background noise

Using Debian Wheezy
Audacity 2.0.1
Distribution release

I would like some help. I have a recording where I am trying toi listen to a speaker and the background noise is too loud and I would like to cut the volume down, or isolate the speaker and save this to listen to.



If you can’t understand the speaker, the best we can do is the telephone filter under Effect > Equalization. The other tools such as Noise Reduction need you to know exactly where the words are.
