Engine sound simulator, in your browser
Nothing here is a recording. Crank Shed simulates the engine and makes the sound while you drive it.
It tracks crank angle sample by sample, opens each exhaust valve in firing order, and sends the pressure pulse down a modelled pipe that rings at its own length. An inline-4 and a V8 sound different here for the same reason they do in a garage: the pulses arrive at different times. Change the firing order or the pipe and the sound changes, because the pulses actually move. How it works.

- Shed Four, Inline-4. Even, buzzy, climbs fast.
- Big Cross, Cross-plane V8. Uneven per bank. That is the burble.

Questions
Is it free?
Three engines, the dyno and share links are free with no account. Pro is a one-time unlock.
Does it work on a phone?
Yes, and it was built for one. Sound set to Phone re-makes the low end as overtones a small speaker can play, since a phone cannot move air at 40 Hz. Headphones sound better on Full.
No sound on an iPhone?
Turn the volume up and check the ring switch. Older iOS versions mute web audio when the switch is on silent.
Does it work offline?
Yes. After the first load it runs with no connection, and you can add it to your home screen.
Are these real engines?
No. They are generic layouts with made-up names. None is meant to copy a particular car or bike.
