Few engine loops i've been doing. I've yet to start on the Cruise start and stop since i need to find a few sounds i can work with and something that sounds remotely "good"/Suitable. And i've also had to adjust attenuation values in the Engine_sounds.ini so that the rumble doesn't take over 90% of the ship engine sounds in total and so that you can hear the actual engine sounds more clealy when in impulse.
The problem with sounds is that i need to create an effective loop, one thing that I've tried hard to do is to iron out things like crackling and clicks within the audio. You may notice them in these videos but thats because of crappy audio encoding for MP4, you'll find that if you were to play this in-game (Take note that i use High quality headsets) there is minimal to no cracking in these loops. Its a kind of OCD/Autistic thing i have apparently. Thats what the doctors say anyway.
I still need to experiment around some stuff so this will take time.
(Adjusted attenuations: Sound of the rumble is quieter, Sound of the engine is louder!)
