As we all know, sound is a rejected element and for a good reason.
But what if the much suggested element speaker actually did exist, but only did simulate a speaker?
I am obviously talking about whats basically a pulsing PUMP.
TMP controls frequency, TEMP controls Amplitude (as in the pressure it creates in its square.) And, maybe, TMP2 could control the direction it fires off to, but thats experimental.
At 60 FPS the highest frequency you could achieve would be 30 Hz. Any higher than that and the rest of the simulation just wouldn't be able to tell the difference. Even at 30 Hz the rest of the simulation will not really give a flying banana about pressure changes. Add the fact that this is kinda achievable with subframe already (a native implementation wouldn't do any better than subframe would) and you get a completely pointless element.
Well, I tried.
As for subframe, that stuff is magic anyway, so implementing it is beyond like 90% of people.
You can achieve this using PUMP and well-timed electronics
