Free Vehicle and Engine Sound Effects: Cars, Trains, Planes

About these vehicles & engines sounds

Vehicle sound effects do two jobs. They tell people what's showing up, and they set when and where the scene is. Old Car Starting and Diesel Pickup Starting and Running have cold starts and idles. Snowmobile Brap Brap Revving and Turbo have the revving. Non-Working Motor and Overheated Engine are for when something's wrong. There are bigger ones too, like Airplane Takeoff and Train on Tracks With Horn. 1800s Train Steam Whistle works for period pieces, and Police Sirens for city scenes. Use them for arrivals, chases, establishing shots and traffic in the background.

Think in steps, not single clips. A car pulling up is approach, brakes, idle, shutdown and door. Leaving is start, rev, pull away. Pick a recording with the step you actually need, instead of trimming a long take badly. Engines all sound different. A diesel pickup sounds nothing like a four wheeler. And a turbo adds a whistle people connect with a modified car. In a period piece, a steam whistle or an old engine starting sets the era right away. If it's far away or off screen, use a recording made from a distance instead of filtering a close one. Real distance changes the whole sound.

Loop the idle, not the whole take. Find two zero crossings in a steady part and crossfade by a few hundred milliseconds. That gives you a bed you can run under dialogue as long as you want. Engines take pitch and speed changes really well. Shift one down a few percent and it sounds like a bigger engine. Shift it up and it sounds strained. A slow pitch ramp can even fake speeding up from a steady idle. For pass-bys, use a Doppler plugin, or move the pitch by hand and pan it. Roll off everything below 40 Hz unless you want the chest thump. And keep sirens out of your dialogue's frequency range so the words stay clear.
