Free Explosion and Fire Sound Effects for Action Scenes

About these explosions & fire sounds

You get big explosion sound effects here, plus the small fire sounds that set them up. On the big end there's Wartime Bomb, Nuclear Incoming With Explosion, Submarine Implosion and Cinematic Explosive Decompression. They've all got enough low end to carry a disaster moment. Firecracker Bangs and Screaming Firework are more street level, for celebrations and chaos. 8-Bit Explosion is for retro games and pixel animation. Then on the fire side there's Lighter Flick, Blow Torch, Mini Blow Torch and Plasma Lighter. Those are for close-ups of something getting lit. Reach for these when stuff blows up, catches fire, or there's danger just off screen.

Size is the main choice. A firecracker is a sharp crack with almost no tail. A bomb is a punch, then two or three seconds of rumble and debris. Match the tail to the space you're showing. An explosion in a canyon should ring out, and one in a field shouldn't. If the blast is off screen, use a distant, filtered version. That works better than a close one turned down. For retro or simple-looking visuals, the 8-bit ones fit a lot better than realistic audio. Keep small fire sounds like a lighter flick dry and close, since they usually happen right next to the camera.

Explosions eat up headroom, so go in with a plan. Split the blast up into the sub below 80 Hz, the middle and the debris. Then control each one on its own. The sub is what people feel. The debris is what makes it believable. Duck the music and dialogue for about half a second around the peak. Bring them back as the tail dies down. A short bit of near silence right before the blast makes it hit harder than any amount of gain. Watch the true peak too. A limiter set to -1 dBTP stops it from distorting after a platform encodes it. For fire loops, crossfade two different sections so you can't hear the crackle repeating.
