I recorded a nearly complete Dogs game yesterday, but it has some annoying noise in it that I can't get rid of with my puny audio skilz and Audacity.
If anyone else wants to take a crack at these files, please contact me.
Actual noise, especially air-handling noise (e.g. fans) or electromagnetic noise (e.g. some fluorescent lights), is very difficult to remove. I recorded my own radio drama once, and that was the biggest problem by far. I suggest trying a low-pass filter or a high-pass filter, depending on whether the noise is low frequency or high frequency. Good luck!
