This is a scratch built full 3D sound set for Manfred Jahn & Team's wonderful C-47 Skytrain package. While flying the C-47 in the sim I felt there was some room left to improve the engine sounds. And what started as messing around with parameters ended up in me composing an entirely new sound set starring the Pratt & Whitney R-1830.
The sound set attempts to push the boundaries of what is possible in FSX/P3D. If you fly the C-47 in a realistic manner, this sound set will provide a realistic sound environment. No less than 17 samples are used per engine in order to recreate the external sound environment (everything 44,1KHz high quality audio) while making extensive use of sound cones to cover all the angles. In fact this sound set uses source material from 4 real life C-47As.
All of the aforementioned results in a "study level" sound set that hopes to do justice to the real thing.
Pro tip: don't turn up your subwoofer all the way... or DO but don't blame me
