Some ideas to augment sounds "realism" in the realm of possibility for 0.31
-Jet startup sounds (shamless plug of me)
Was announced in a dev stream afaik and may come in the next patch but anyways
-Doppler delay for guns, since they've been added to explosions Im assuming making it a thing for players could be "easy"
-Increasing sounds of guns, the cockpits can stay the same but the sounds are generally drowned by the engines, even the compass guns gets a little muffled due to the engines
-"Longer ranged" plane sfx, rn we barely hear planes until their quite close to you im thinking some kind of "howling" for further away jets could play or anything similar for any veicules
-if possible a fix to the looping of sounds in the game as this as been an issue since early playtest im wondering if a fix would be possible
