The female voice recording has a lot of crackle noices.
For some reason, after about ten minutes of recording, those crackle noises start, and I don't always notice them until they get bad, because I'm focusing on the Klingon sounds, and subconsciously tuning out the non-Klingon ones. I have re-recorded.
Hmm, that's wierd...
Thanks for the answer and recordings.
