This sounds like an old mississauga transit (mi-way) bus engine starting, running for a short time, then slowing down. The sound was made by simply playing the sound of air raid siren backwards.
The sound of a car starting engines on the street. The sound was captured using two beyerdynamic mc-930 setup for stereo recording using x-y positioning. Preamp used was avalon ad-2022. Usb interface used was audient id22. Raw sound recorded in stereo at 96khz.
Sound of a pickup truck. Keys jingle, door shuts, starter click, engine turns over and sits idle, tires roll over gravel slowly, then truck drives away. Normalization applied.
Airplane passing overhead, 50s sounding engine. Lots of sub rumble, very dynamic sound effect. Sounds very close, like the plane is passing barely above.
