Sharp, airy blade swings with a thin metallic ring at the end. They sit somewhere between a classic sword swoosh and the "sword qi" projectiles of wuxia and xianxia games, so they work for both a katana swing and a glowing crescent of energy flying across the screen. Every press of New in the editor brews a different sword slash; these 12 are a fixed selection so the links stay the same.

Good for

Melee attacks and combo hits
Sword qi, wind blades and energy slashes
Parry or blade-draw moments
Skill icons that cut across the UI

Tweaking tip

For a heavier weapon, lower the noise layer's cutoff and shorten the ring. For a magical slash, raise the reverb. Open any variant with Edit to change it with sliders.

License

Free for commercial and non-commercial use. No attribution, no sign-up. Most sounds are synthesized from scratch; the few that use recordings use CC0 (public domain) recordings, so there are no third-party rights attached.

Generate them from code or an AI agent

The same sounds are available from the command line:

npx sfxbrew swordQi --count 5 --out assets/sfx/sword-slash.wav

Or let Claude Code, Cursor or any MCP client add them to your project, then ask for "sword slash sounds":

claude mcp add sfxbrew -- npx -y sfxbrew mcp
