SoundCraft AI - Sound Effects Generator + Library

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

1. Enter your Asset Store invoice number (from your purchase confirmation email) and click Verify.
2. Type your prompt, e.g., "heavy iron sword hitting plate armor."
3. Optionally pick a sound engine, style preset, duration, and how many variations you want.
4. Click GENERATE.
5. The cloud AI generates your sound effect(s) and returns the clip(s).
6. 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.
7. Drop the clip onto any AudioSource — or, if you enabled it, drag the ready-made AudioSource prefab straight into your scene.

📚 THE SOUND LIBRARY

Browse, organise, and reuse everything you generate from one Mixamo-style window (Window → SoundCraft AI → Library):

✅ THREE-PANE BROWSER — A category sidebar, a searchable card grid with live waveform thumbnails, and a preview pane. Your whole sound palette at a glance, however many hundreds of clips you make.

✅ SEARCH, SORT & TAG — Find any clip by name or your own custom tags. Sort by name, duration, or most recently added, and star the sounds you reach for most.

✅ PREVIEW & PLAY — See each clip's waveform and audition it instantly in the Editor — no Play mode required.

✅ ONE-CLICK ADD TO SCENE — Drop a sound straight into your scene as an AudioSource that's already tuned for its category (2D/3D, looping, rolloff, distances).

✅ MANAGE IN PLACE — Rename, duplicate, re-categorise (a real folder move), and delete clips without ever leaving Unity. Tags and favourites are saved per-project and never touch your assets.

⚠️ WHAT'S INCLUDED VS NOT INCLUDED

SoundCraft AI generates sound effects for any game project. Specifically what's covered:

• ✅ One-shot SFX — UI, weapons, footsteps, impacts, creatures
• ✅ Looping ambience and short music cues
• ✅ Sound Library browser — search, tag, preview, and manage every generated clip
• ✅ Mono and stereo output
• ✅ Automatic categorisation, one-click variations, and per-category import settings

Not included (be aware before buying):

• ❌ Voice, dialogue, or speech generation — SoundCraft AI is for sound effects
• ❌ Full-length music tracks — the Music category covers short cues and stingers, not complete songs
• ❌ A fixed pre-made sound library — SoundCraft AI generates on demand rather than shipping a static pack
• ❌ Offline generation — an internet connection is required to generate; generated clips then work fully offline forever

If your project needs full musical scores or character voice-over, plan to source those separately.
