Real growls and roars, pitched down or up at random and reinforced with a low chest rumble. Lower variations sound like big beasts and dragons, higher ones like smaller creatures. Every press of New in the editor brews a different monster growl; these 12 are a fixed selection so the links stay the same.

Good for

Monsters, beasts and dragons
Boss intros and enrage phases
Enemies noticing the player
Demonic or spirit beasts in xianxia games

Tweaking tip

Transpose further down and add reverb for a giant boss in a cave. 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 monsterGrowl --count 5 --out assets/sfx/monster-growl.wav

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

claude mcp add sfxbrew -- npx -y sfxbrew mcp
