Well, I've started to clean up the audio tracks for FS1, I had an idea for it at first but I scrapped it entirely. I started a thread in Freespace Modding, with an admittedly bad start, thinking of running the files through the X-Fi Crystalizer. That sure didn't work out well, but I've taken a different approach, just audio cleanup, and then to re-encode the altered WAV's into OGG files. My main goal is to get rid of the "fizz" and high-frequency "hissing" around the audio, to make it sound cleaner than the unaltered WAV's. Keep in mind that this is just audio cleanup. The quality really doesnt improve much, but getting rid of the hiss and fizz makes it a little more enjoyable. Cleaned up OGG-ified audio tracks for FS1. I have posted a new sample in the thread I mentioned above.
Just curious if you might be interested in something like this.
