Removing Static

So,
I'm trying to remove the static that is plaguing some church sermons that I have doing for our church(online sermons), but audacity demands that I provide a noise sample before it can do so. However, I don't think my recording have noise samples at the beginning or the end of the recording so is there like a default microphone noise sounds I can use?

The sample I am talk about is this:

So, I don't think I can find any static at the beginning or end.

Can anyone give me pointers?

The bad news is that's not static. You have a damaged capture. There are actually little, tiny pieces of the voice performance that are missing. Each gap sounds like a little bubble or pop.

There's only about a billion things that can cause that, so it's your turn to tell us all about your capture system. Don't leave out any model numbers.

I'm using M-Audio Session with Fasttrack USB( I don't think there was a model number, not sure though). We are recording with a microphone with an XLR cable.

There are some problem with the original recording but a lot more when I tried to slow down the original track of 25 minutes and stretch it to 33 minutes so the speaking wasn't so fast.

However, is was still present in the original recording.

<<<M-Audio Session with Fasttrack USB>>>

Close enough. Try changing your USB connection or unplugging and plugging the original one several times. Restart Windows.

When was the last time you defragged your PC hard drive? How full is it? Audacity will create damage like this if the hard drive is crowded or not neat and orderly.

What kind of Virus Protection do you have?

<<<a lot more when I tried to slow down the original >>>

I don't like the way Audacity 1.2 tools work for that job. You can install Audacity 1.3 and 1.2 successfully, but if you try to actually use them at the same time, verily the wrath of the computer will rise up and smite thee. Only run one.
