Yes, I was going to run these through Audacity. There were 70 total files, each about 45 minutes, but there's a ton of white noise on them. They're also in no particular order, so I'm renaming them to follow a chronological file system order so that they can easily be followed in order. I'm not sure they're "complete", but 70 45-minutes talks is a treasure trove.
Yes they are a treasure.
If you want more control over what you do to the audio, in removing the white noise, you can use a "graphic equalizer" where you have control over each band. Usually the highest ranges you slide all the way down to 0 (totally squelch them) and as you get closer to "human speech" range, you be more careful, maybe attenuate it a bit, but only halfway, or 3/4 of the way, etc.
That's how I processed many of my chant recordings, to remove white noise hiss from the recording.
A helpful tip is to run the filter, listen to it, hit UNDO, listen to it again, then hit REDO, and listen to it again. That basically allows you to A/B test back and forth, to see how you did.
