The problem is that i use a compressorsound in this case for simulate the "airfilling" sound that you hear in this train.
I think that this is so, becauze the black air pillow need air too.
But when the compressor run, and pump air to the foodpressure (Red needle), this train make that filling sound until the compressor stops working.
The traindriver that have record that sounds for me few years ago, have explain me that like this too.
On this old movie you can see what i mean (MSTS):

Better than that i can not explain.
I dont know if there are other trains in whole world that have compressor in other piece of train, and have a "filling" sound like this. For 1 special case like this is change code is maybe ask tomuch.
My plan B is, AirBrakesAirCompressorWattage First was 15000 on .eng of middle wagon, i have now remove - in all .eng files of this type EMU and use AirBrakesAirCompressorWattage ( 5000 )
Sounds in cabview like in real, isolation & material of every train class is differt. Newest trains have better isolation, but more polyester on it, than older trains that have more metal/asbest on it.
I make my sms files Always with sound of inside, and outside, if you listen good the time between inside and outside sounds are not same. I have report that problem more than 1 times in other topics.
Soundmanagement of ORTS have some problems (time not same, sound in cabview that hidding and comes onley back if you change to other view and turn back...) and it is not @ same PC/Notebook, that means it are not issue's of
onboard sound cards...
You can test it easy, when you use the horn in cabview. than go to external view, and normal you hear there horn again. And so it is wit all sounds. (a Timegab)
I thouth first there was a mono/stero problem of Hz problem in the .wav files that not mach with .sms or curvepoints that are not on same place... but that was ok.
Back on topic: If nobody find it usefull too have sound of compressor (fill simulation example) and nobody will change the code for situations like this, than i test now with
no "-" and tuned AirBrakesAirCompressorWattage (TOTAL Watt:3)
