  From your description of the audio, it is going to be hard to fix, as white noise tends to cover a very broad frequency spectrum and so is hard to get rid of without losing what you want to keep.
  A decent starting point for you would be to use a freeware audio editing program like [Audacity](http://audacity.sourceforge.net/). Here is a [noise removal tutorial using Audacity](http://wiki.audacityteam.org/index.php?title=Noise_Removal).
  
  You can also use audacity to cut out sections where there is no background talking. Then you can use an effect called a **compressor** to attempt to raise the level of the speaking to a better level, although you may still find you are amplifying some background noise. Here's a description of the [audacity compressor](http://wiki.audacityteam.org/wiki/Compressor).
