Audio Blueprints – Unreal Engine 4

Here’s a small collection of beginner-level audio blueprints for Unreal Engine 4. Will hopefully be expanded on with time.

Fade in sound


This is a small node setup for an actor BP where you spawn and fade in a sound on trigger overlap. The fade-in here is set to happen over 10 seconds, but can be set to whatever you like, and defaults to 0.

Sound cue with random pitch


Once you have created a sound cue, you can add some variation to your sound by adding a modulator node, and set the min and max pitch of the sound played in the details panel. This will make the sound vary in pitch every time it is played. Small changes like this makes gameplay a lot less repetetive.
