Brians fs9 thunder sound enhancement v3 hello fellow simmers! I noticed fs9 thunder effect is a low rumble.. . well, ive made some ajustments, the files are still mono, which pan in stereo.. . are about the same size, and have the same generation, but sound like real lightning bolts, its the same lightning bolt, in, and out of the cockpit, eventhough the cockpit effect is 3 dbls lower. I recommend the fs9 sound settings i have indicated, speaker volume should be adjusted thereafter, for optimal enhancement. enjoy Brian Neitzel pcguru_at_inbox. com
