I am new to GM'ing EP and last weekend had a GREAT time running my first adventure, which was Continuity. As I was preparing to run it, I decided I wanted to make my own audio files to use throughout the adventure, so I re-created the Hans files using background (interference) noise and a voice synthesis page I found online here:
I used the voice "Selene" which has a UK accent. I renamed the AGI "Mother" (tip of the hat to Alien) instead of Hans. I added extra syllables to make it sound like she was really malfunctioning.
The interference I took from this website:
Pick your favorite!
I laid this over a klaxon that I had looping from
(I liked klaxon1distant.wav the best, and just kept it looping until the party was able to shut the airlock successfully. It really contributed well to creating an ambiance and sense of urgency!)
I also kept Steve Roach's "Darkest Before Dawn" playing on continuous loop. The track is an hour long, and isn't too intrusive, so it also contributed to the ambiance greatly. Here's a 4 minute sample so you can get a feel for it:
I had to use the "mixer" in the volume control panel to set the volumes properly.
Hope this is helpful! If anyone would like the audio files of Hans ("Mother") I'll include the link below:
