Hold a scene together with one steady tone
A drone under a slow dialogue scene keeps the cut from feeling bare, in a film, an audio drama or a game cutscene.

よくある質問
What is a long sound effect?
It is a sound that holds rather than hits: a drone, a hum, a sustained note or a rising tone. These sounds run steadily through a scene instead of landing on one frame.
Where can I get sustained sounds for a video?
Describe the held sound by how it is made and generate it. Each clip on this page came from the prompt beside it, so you can copy one and swap the instrument or the pitch.
How do I make a custom drone or sustained tone?
Start with the mechanism, such as "a bowed cello holding one note", then add "continuous, unbroken, no gaps". Name the pitch and any wobble or rasp you want to hear.
How do I make a held sound last longer in my edit?
Clips are short by design. Overlap a second generated clip and fade between them, or lay the tone under your picture and hide the join with a slow crossfade.
Can I use these long sounds commercially?
Yes, audio generated on paid plans can be used commercially. See our terms for full licensing details. A generated drone is also unique to your project.
Why does my drone keep changing instead of holding?
Extra words invite the model to add movement. Say "one steady tone" and "unbroken", name only one instrument, and leave out any word that suggests a story or a change.
