Question 1

What is a rumble sound effect?

Accepted Answer

It is a sustained low roar with no sharp attack: rolling thunder, a shaking earth, a heavy engine, a distant slide. It works from underneath a scene, giving it weight and tension and telling the audience something large is happening or approaching, often before the picture shows it.

Question 2

Where can I get rumble sounds for a video?

Accepted Answer

Generate them rather than search for them. Describing the rumble you want takes less time than digging through a stock library, and you get the exact low roll your scene needs instead of the closest available clip. Every sound on this page was made from the prompt printed beside it, so you can start from one and adjust it.

Question 3

How do I make a custom rumble sound effect?

Accepted Answer

Describe the source of the low sound, whether it holds steady or builds, and how rough it is, then generate it. Open with the movement rather than the name, like "a deep grinding roar of the ground shaking, continuous and unbroken", which gives Morphic enough to work with, and adjust the wording until it fits your cut.

Question 4

Why does my rumble come back broken up instead of continuous?

Accepted Answer

A rumble is a sustained texture, and if the prompt names it without describing the movement the model tends to return a few separate pulses with gaps between them. Open with the mechanism, describe it as an even low roar, and add "continuous" or "unbroken", and it comes back as one solid roll instead of scattered hits.

Question 5

Can I use these rumble sounds commercially?

Accepted Answer

Yes, audio generated on paid plans can be used commercially. See our terms for full licensing details. Because each sound is generated rather than pulled from a shared library, you also avoid the clip turning up in someone else's video.

Question 6

Why does my rumble not sit right in the edit?

Accepted Answer

Usually it is fighting the rest of the mix rather than being wrong. A deep rumble shares low frequencies with music and dialogue, so stacked on top it turns to mud. Give it room in the low end, let it sit under the scene rather than over it, and match its length to the shot, and it holds the weight without swallowing everything else.
