VARCO Sound generates the audio your game needs, right inside Unity: sound effects, music, creature voices, and dialogue, all from a single plugin. Describe what you need, or drop in a screenshot of your scene, and get usable audio in seconds.

No audio experience needed. Generate a sound, create alternate takes with variation, loop it for ambience, or edit it in place, then drop the result straight onto an Audio Source.

WHAT YOU CAN DO

Sound Effects: Type what you want to hear and generate it. Footsteps on gravel, sword swings, UI clicks, explosions, rain, a magic spell, anything you can describe. Not sure how to word it? Use Improve Prompt for suggestions, or Suggest from Image to get ideas from a screenshot. Generate a batch at once and keep the takes you like.

Music: Score a scene from a short prompt like "tense dungeon ambience" or "upbeat village theme," from a reference image, or from both together. A quick way to get background and theme music that fits what's on screen.

Voice: Turn text into natural speech for dialogue and narration, in Korean, English, Japanese, and Taiwanese. Pick a speaker and adjust speed and pitch to fit the character.

Creature: Record a line yourself, then reshape it into a monster, dragon, or beast using any clip as the target voice. What you say and how you say it stays the same, only the voice changes.

Variation: Generate alternate takes of any sound so repeated footsteps, impacts, and gunfire never play back identically. Vary the whole clip, or select just part of it on the waveform.

Loop: Turn any clip into a seamless, gap-free loop for ambience. Mark a region to keep, and let the tool find a clean loop around it.

Built-in Audio Editor: Refine any clip without a separate DAW. Trim, cut, fade, crossfade, normalize, adjust gain, reverse, or convert to mono, then apply it back or save it out.
