This is my first ever add on for orbiter.
This file adds the Apollo 8 Pre-Countdown Audio for T - 5 Minutes to Launch.
For use with AMSO
(I have also reduced the volume of countdown.wav to match the pre-countdown audio and also after launch volumes)
I reccomend you also download Apollo 8 Sound Pack for amso by kino_astroboy

This zip file will overwrite your Sound / AMSO / AS-503 (pre-countdown.wav and countdown.wav) files so BACKUP these files.
