Using Sound Effects for Film & Video

Sound effects have the ability to better engage your audience, support action we see on-screen, and enhance your music. Here are a few quick tips for getting the most out of this free sound effects pack:

• Change SFX speed or reverse it. With new advancements in video editing apps, you can not only change the speed of any audio, but you can also preserve the pitch as well. This is especially useful for SFX that build – you may need to speed up the build, but you don’t want it to sound like high-pitched chipmunk squeals. Also, with some SFX you can create really interesting sounds by simply reversing the audio (again, easy to do in most NLEs).
• Layer, layer, layer. Often sound effects work best when layered and combined. With trailers, where the sound design may be dense, you may need to overlay multiple SFX to really build out the sound palette. Take a look at how we layered the SFX for the demo video above:
• EQ your SFX for maximum punch. Want to bring out the bass in your drum hits? EQ. Putting a simple EQ filter on your sound effects can make them punchier, but be mindful of your levels. You likely never want the SFX to distort, get blown out or over power dialogue.
• Add audio filters and effects to the SFX. Most video editing applications have at least a few basic audio filters that, when applied to SFX, can dramatically change the sound and feeling. For instance, adding reverb may make an effect sound more ethereal, whereas distortion may work well for a gritty horror or sci-fi trailer. Experiment with filters to customise the sound to fit the needs of your project.
