Make an Explosion for Your Game Today

Sound effects are integral to how your game is perceived by the player, and you’re here to make an explosion for your game today. Unfortunately, most of us don’t have a car that we can blow up to get that perfect, license-free explosion sound.

Fortunately, there is a free tool called Audacity that allows you to edit sounds on your computer, and you know what we’re going to start with? A clap. That’s it. We’re going to start with a clap and end with a believable explosion sound. So let’s get to it!

Step by Step Instructions to Make An Explosion Sound with Audacity

  • The first step to make an explosion for your game today is to install Audacity if you have not already done so. Click here to go to Audacity’s download page.
  • Once you’ve installed and run Audacity, you should see the following.
  • Let’s do some preparation work. Leaving about a third of the trailing sound, select the rest and then press delete to remove the sound. Then, select from the beginning of the track until just before the clap starts, and then press delete. This will ensure that your explosion occurs on demand.
  • Press CTRL+A to select your whole track and then we’re going to click the “Effect” menu, and select Paulstretch as shown in the next two images. If the settings are not already as below, adjust them.
  • Two more steps, now that the sound is stretched out, we want to get rid of some of the noise. This part may be up to your discretion a bit, but select about where you see my noise jump up about 60% of the way through the sound, and then highlight until the end. Click the Effect Menu and select “Noise Reduction…” You have to have the section you are working selected with before you click this option and you’ll have to click “Get Noise Profile” and then the window will close. Open it again and click “OK.”
  • There you have it, you’ve turned your clap into a passable explosion sound. You can play with the settings above, and other settings too to tweak it, but this should be a great place to start.

To the trained ear, of course, you will know it’s not a major explosion, but it’s a passable one if you don’t want to expend too much time or energy on your game at this point. You can also use these methods to produce other sounds, such as bubble popping, add bass to a knock on the table to make it scarier, you can do a lot with Audacity to help you make your game today. I hope you enjoyed this tutorial to make an explosion for your game today!
