I'm an audio engineer, I recommend downloading and checking out Audacity, as well. Then import the file, save it, and then try selecting parts or all
of it and use some of the effects.
There is a picture of the Audacity interface - you could try compressor (this makes the sound file softer but cleans it up), high pass filter, low
pass filter, clip fix (this fixes the clips, or the audio peaks that cause crackling), noise removal, leveler, compressor, click removal and maybe
bass and treble in order to amplify the sounds you need.
