AI sound effect generator: make SFX and music on OmniArt

Sound is the half of a clip most creators leave to chance. A good shot lands twice as hard with the right whoosh, room tone, or score underneath it — and OmniArt's audio workspace generates all of it from a text prompt, next to the image and video tools you already use. This guide covers what you can make, which audio models to reach for, and how to build a finished soundbed without leaving the platform.

The point of generating audio on OmniArt isn't just convenience. When your picture and your sound come from the same workspace, you can iterate on both against the same brief — re-cut a video and regenerate its Foley in the same session, instead of round-tripping through three separate tools.

What you can generate

OmniArt's audio models cover four jobs that used to need four different subscriptions:

  • Sound effects (SFX) — discrete hits and textures: footsteps, impacts, UI clicks, whooshes, magic, weapons, nature one-shots.
  • Ambience — continuous beds: rain, city traffic, a busy café, wind through trees, server-room hum.
  • Voiceover — narration, character lines, and multilingual dialogue from text, with control over tone and pacing.
  • Music — full tracks or loops by genre, mood, and tempo, for backgrounds, stings, and brand cues.

Tip

Describe the function of the sound, not just the object. "A heavy wooden door slamming in a stone hall, with a long reverb tail" gives the model far more to work with than "door sound".

The audio models on OmniArt

Different models win at different jobs. OmniArt brings them into one workspace so you can pick per task instead of per platform.

ModelBest forNotes
MiniMax Speech 2.8 HDHigh-fidelity voiceover and narrationStudio-grade clarity; the default for polished VO
MiniMax Speech 2.8 TurboFast drafts and high-volume dialogueQuick iteration when you're testing lines
Eleven Multilingual v2Multilingual voiceover with stable deliveryReliable across many languages
Eleven v3Expressive, emotionally varied performancesReach for it when delivery needs range
Eleven Turbo v2.5Low-latency speechGood for long scripts and rapid passes
MiniMax Music 2.6Full music tracks by genre and moodBackground scores and brand cues
ElevenLabs MusicStructured songs and loopsSection-aware music generation
Google Lyria 3 ProHigh-quality instrumental and cinematic musicScoring trailers and narrative video

The right choice depends on the brief: HD speech for a finished narration, Turbo for testing twenty alternate lines, Lyria or a music model for the bed underneath. You don't commit to one — you switch as the shot demands.

How to generate a sound effect, step by step

  1. Open the audio workspace and pick a model that fits the job — a speech model for voice, a music model for score, and the SFX/ambience flow for effects.
  2. Write a descriptive prompt. Name the material, the action, the space, and the tail: "glass bottle shattering on tile, close-up, short bright transient, minimal reverb."
  3. Set duration and variations. Generate a few takes so you can pick the cleanest transient instead of settling for the first result.
  4. Audition and refine. Adjust the prompt for length, brightness, or weight — "heavier", "more distant", "drier" — and regenerate.
  5. Export or carry it into a video. Keep the asset in your workspace so it's ready to drop under a clip.

Pairing audio with image and video

The real advantage shows up when modalities meet. A product clip rendered in OmniArt's video workspace can get a custom whoosh on the camera push, room tone under the whole shot, and a Lyria score behind it — all generated in the same place. For a faceless explainer, generate the script as voiceover with a speech model, then cut your visuals to match the narration's pacing.

Note

Working across modalities is the core idea of OmniArt: image, video, and audio are one workspace, so your assets stay in sync as the brief evolves. See all AI video models in one workspace for how the same logic applies to video.

Getting started on OmniArt

Start with a single 5-second clip and build its sound in layers: one SFX hit, one ambience bed, one short music cue. Generate each with the model best suited to it, audition a few takes, and stack them under your picture. Once the layered approach clicks, scaling up to a full reel is the same moves repeated.
