Voice Of The Starship is a plugin designed to produce environment noise—not just natural, but unnatural environments. Namely, spaceship rumble, like what you heard in episodes of Star Trek. It defaulted to a seashore-like effect, with random surges that fall away again. In stereo, these ‘waves’ hit at different times on left and right.
If you’d like this plugin, buy its successor Noise, and ask me for it by email. I’ll send it.
