Spoiler alert regarding a video of a NAEV mission that shows off the sound capacities of the game. The project relies on OpenAL Soft.

You should come for the sound [10MB vorbis rip]* or for the HD version.

Effects to notice:

• Positional sound (basic for OpenAL)

• Doppler Effect (depends on velocity)

• Air absorption factor (sounds like you’re under water)

• Reverb (also helps make it sound like you’re underwater)

• Speed of sound changes (depends on nebula density – also for sounding underwater)

* It'd be great if more project took so much care of audio licensing so there could be f-a-i-f game sound walks. Great distraction from urban noise. Game soundtracks are disturbing though mostly.
