Cleaning up audio files

[Hulk]

I recently purchased a Olympus digital voice recorder for recording lectures. The sound is great but I was wondering if there was a way to make it even better by editing it.

What kind of software will polish up the quality of the audio? The recorder already has a built in voice filter, etc.
