An AI sound effects generator is a tool that creates a sound from a written description instead of searching a library for one. On Trendai.video you describe the sound, pick 5, 10, 15 or 22 seconds and get two different takes as MP3s, made as a loop if you ask. Or upload a 3 to 20 second clip, and the AI adds sound effects that match the picture, with optional background music, returned on the video and as an MP3.

Make: Sound for my videoUse this example →Sign in to the AI sound effects generator and choose A sound from text, or Sound for my video and upload a 3 to 20 second clip.
Write what you want to hear, up to 450 characters, with the source, the space and the mood. In text mode pick the length and whether it should loop.
Press Make the sound. It usually takes a few minutes. Play both takes or the new video, download them, or find them later in My Videos.
Each text job makes two separate versions of your description, so you can pick the door slam with the better thud or keep both for variety in an edit.
Choose 5 s for a whoosh, impact or notification, 10 or 15 s for a short scene, or 22 s for a long ambience bed. The sound is made to that length, not padded with silence.
Turn on Loop it and the sound is made to run back into its own start, for rain, engine hum, crowd murmur or a game menu background.
Upload a 3 to 20 second MP4 or MOV, such as an AI-generated shot or a muted B-roll clip. The AI watches it and adds footsteps, wind, traffic or splashes in time with what happens on screen.
In video mode, describe a music bed in a few words, like calm lo-fi beat, and it's mixed in under the effects. Leave it empty for effects only.
Video mode returns your clip with the new soundtrack as an MP4 and the same sound as a separate MP3, so you can use either in your editor.
Libraries mean keyword searches and auditioning dozens of files that are almost right. Describe the sound and it's made for you.

A 30-second product Reel with quick cuts feels flat without transitions. Make a set of short sounds and drop one on each cut.
A rainy-window stream, a cosy café background for a study video or the menu screen of a small game needs a bed of sound that never ends.
Clips made by a video model often come back silent or with sound you don't want. A 10-second shot of waves on rocks needs to sound like the sea.
Add transitions, reaction sounds and ambience to TikToks, Reels and Shorts without searching through sound packs.
Make placeholder or final sounds for footsteps, pickups, doors and looping level ambience in minutes.
Give silent generated shots footsteps, weather and music so a sequence of clips plays like a scene.
Set a scene in an audio story with a creaking door, a storm outside or a busy street under the narration.
