How are sound effects created?
Sound effects are created using a range of techniques including sound recording, synthesis, and sound processing. Sound designers work closely with filmmakers to identify what sound effects are required for a film. They then capture or create the audio needed to make the effects, shape the effects using music software, and add the completed effects to the film.
All kinds of sound effects might be required for a film, from the smallest detail (a creaking door or swishing curtain) to the most dramatic explosion. Some of these sound effects relate to action happening on screen, while others – such as impacts and risers – exist outside the “world” of the film alongside the musical soundtrack.
How do people make sound effects?
Sound designers make sound effects using a combination of synthesizers, recorded sounds or samples, and sound shaping with audio effects and other tools. Some sound designers may record audio on the set of the film or in their own studios, while many get sounds from professional sample libraries or create sound effects from scratch using synthesizers. However a sound designer gets their audio, they’ll then need to shape it into the final effect using editing, arranging, and audio effects such as EQ and distortion.
How to generate sound effects
You can generate sound effects using tools that are easy to get hold of – you don’t need to be a professional sound designer to make great sound effects.
You could start by recording your own sounds using a microphone and audio recorder. If you don’t have this equipment, sound libraries offer a wealth of great sounds for creating sound effects. Professional sound libraries charge a subscription, but there are also free libraries such as Freesound and Free Sounds Library.
Native Instruments also offers thousands of pro-grade samples, from evocative atmospheres to cutting edge sound design and orchestral instruments. Explore cinematic sound libraries from Native instruments.
You might even want to create your own sounds from scratch using a synthesizer.
Once you have your sounds, they need to be shaped into sound effects. For this, you’ll need music software such as a DAW and audio effects like EQ, reverb, and distortion.
Komplete Start gives you seven audio effects perfect for creating sound effects, as well as samples, synthesizers, Kontakt instruments, and more – and it’s completely free. It’s a great place to start on your sound effects journey.
With a box of audio tools at your disposal, you’ll be able to start shaping your sounds into convincing effects. We’ll look at exactly how to do this in the examples below.
How to create 6 popular sound effects
1. Impact
In modern film, Impacts – or hits – are used like punctuation marks. These dramatic booms and clanks can emphasize shocks, climaxes, and transitions on screen. You’ll find them in action and horror movies, and they’re all over Hollywood trailers.
The trick to creating an impact effect is layering. One percussion sound on its own might be a pretty boring hit, but four or five complementary samples can make for a complex impact with weight, personality and drama. Here’s how to do it.
