I've been reading USN sub patrol reports, and there are hints of using Prop Revs-vs-Speed over passive sonar(same as SH3). I've done half the ships, but stopped.. maybe it's time to carry on.
RFB stuffed this up by replacing the hydrophone audio files with real 'pulsating' sonar signatures, resulting in garbage, as the game engine modifies the audio file with it's own speed related rev count.
