Why make sound effects with AI

The exact sound you need

A library gives you what someone else recorded. Describe the material, the space and the mood, and the sound is made for your scene.

Four takes per prompt

Every prompt returns up to four versions side by side. Keep the one that fits and generate again if none do.

Royalty-free WAV files

Use every sound in commercial videos, games, ads, apps and podcasts without licensing fees.

Works with your AI agent

Ask your agent for sounds

Connect SFX Engine to Claude Code, Cursor, ChatGPT or any MCP client. Ask for the sounds your project needs in the same chat where you write code, and your agent generates them, saves the files and wires them in.
