I managed almost the same thing, but I could only get the keys approximately, and had to resort to looking for likely words in the possible keystroke sequences. But I ended up with the same result.
After that, though ... no video! So, I pulled the audio clip into an editor and looked over it. Everything after this is analysis and supposition - I don't know any of this for sure!
The typeball generates a strong audio spike when it hits the paper, while the space bar does not, confirmed by the matching letters while we can see the paper. However, as the typewriter was out of view and the scene was ending, background music was rising and obscuring the typewriter noise. Ah-ha! Since it IS noise, I hard-filtered the clip to between 13 kHz and 15 kHz, guessing that I would get just the typewriter noise spikes. It helped a lot. I was able to estimate how many characters there were in the "orders", and where the spaces appeared.
I ended up with ORDERS_ARE_??_????_?????_???_??????_??????
The best I could get to fill that was...
ORDERS ARE TO KILL PETER AND WALTER BISHOP
Any other ideas for possible orders with similar word counts and word lengths?
