No sign-up. No API keys. No subscription fees. No per-generation fees. No leaving Unity. Just one-click sound effects from text prompts.
This asset generates audio using three AI sound engines - ElevenLabs Sound Effects, MMAudio V2, and CassetteAI. Its Editor tooling was developed with assistance from Anthropic's Claude.
Type the sound you need. Click Generate. In seconds, a game-ready clip is downloaded, automatically sorted into the right category folder, imported with the correct AudioImporter settings, and highlighted in your Project window - ready to drop onto any AudioSource.

💡 WHY SOUNDCRAFT AI
- ✅ NO SUBSCRIPTION — Buy once, generate every month. No recurring fees, no per-generation costs, nothing extra to buy.
- ✅ AUTO-CATEGORISED OUTPUT — Every clip is sorted automatically into UI, Weapons, Footsteps, Ambience, Creatures, Impacts, Music or Other. You never manage folders.
- ✅ ONE-CLICK VARIATIONS — Generate up to 8 distinct takes of the same sound in a single click. Get the variety games actually need for footsteps, impacts, and gunfire.
- ✅ THREE SOUND ENGINES — ElevenLabs for premium quality, MMAudio for ultra-budget batch work, and CassetteAI for the fastest turnaround. Pick the right tool for the job.
- ✅ BUILT-IN SOUND LIBRARY — A Mixamo-style browser for every clip you generate. Search, tag, favourite, preview waveforms, and drop sounds into your scene — all from one window.
- ✅ GAME-READY IMPORT — Every clip lands with AudioImporter settings tuned for its category, and can emit a ready-to-drop AudioSource prefab pre-configured for 2D/3D playback. Zero manual setup.
- ✅ STYLE PRESETS — Retro 8-bit, Realistic, Cartoon, Horror, Sci-Fi, and Fantasy. One toggle keeps a project's whole sound palette consistent.
- ✅ ZERO RUNTIME OVERHEAD — All scripts are Editor-only. Your build size and runtime performance are completely unaffected.
- ✅ INSTANT ACTIVATION — Enter your Asset Store invoice number, click Verify, and start generating. No website signup, no account creation.
🎁 INCLUDED MONTHLY ALLOWANCE
🎫 250 generations are issued every month with your purchase. That is enough for a full project's sound palette — UI, footsteps, weapons, ambience, creatures, impacts, and music cues.
🔄 The allowance is issued every month for as long as you own the asset. Each variation produced counts as one generation; cached prompts return instantly without using your allowance.
🔊 WHAT YOU CAN GENERATE
- UI — Clicks, hovers, confirms, errors, pickups, level-up chimes
- Weapons — Sword swings, gunshots, reloads, bow releases, blade clashes
- Footsteps — On grass, gravel, wood, stone, snow, metal
- Ambience — Wind, rain, forests, caves, oceans, room tone, crowds
- Creatures — Growls, roars, screeches, wing flaps, monster breathing
- Impacts — Punches, crashes, explosions, glass and wood breaking
- Music cues — Short jingles, stingers, fanfares, victory and game-over cues
- And much more — Any sound effect you can describe!
🚀 HOW IT WORKS

- Type your prompt, e.g., "heavy iron sword hitting plate armor."
- Optionally pick a sound engine, style preset, duration, and how many variations you want.
- Click GENERATE.
- The cloud AI generates your sound effect(s) and returns the clip(s).
- Each clip is downloaded to Assets/SoundCraftAI/Generated/, sorted into its category folder, imported with the correct AudioImporter settings, and highlighted in the Project window.
- Drop the clip onto any AudioSource — or, if you enabled it, drag the ready-made AudioSource prefab straight into your scene.
