Built from real recordings of a struck gong and a gong roll. Most variations are a single heavy hit, pitched down for a huge tam-tam or up for a smaller gong. Others imitate the Chinese opera gong, whose pitch bends down or up right after the hit, and a few are a roll that swells to a crash. Every press of New in the editor brews a different gong; these 12 are a fixed selection so the links stay the same.

Good for

Battle start and round announcements
Boss entrances
Comedic or dramatic beats (opera gong)
Martial arts tournament scenes

Tweaking tip

Opera gongs with a rising bend sound playful; falling ones sound like a dramatic entrance. 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 gong --count 5 --out assets/sfx/gong.wav

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

claude mcp add sfxbrew -- npx -y sfxbrew mcp
