I could manage something. Good mic, soundcard, software, and the "Midwestern Accent" that is often referred to as "no accent", etc. Assuming I can find my XLR - 1/4 plug adapter.
I would suggest a slightly topheavy EQ (ie, not much bass, lots of mids and highs - slightly "tinny" to emulate the tiny, cheap speakers in airplanes, etc. I could also add that bit of static when the pilot keys his mic ...
Send me a PM with the scripts and file requirements (codec, sample rate and bit size, etc) and I could have something later this week or early next week.
Wouldn't take much time, so even if you decided not to use them I wouldn't be that upset!
