My 2002 mini cooper with a 1. 6l inline-4 engine at warm idle. Loops seamlessly. Recorded with a roland edirol r-09hr and edited in audacity. If you use this sample, please tell me what you did with it below! links are nice too.
Loop of a diesel engine that i'm planning to use in a game i'm making. Created with audacity from scratch (starting from a fire sound effect also built with an audacity plugin).
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.
