    Engine Plugin
    This product contains a code plugin, complete with pre-built binaries and all its source code that integrates with Unreal Engine, which can be installed to an engine version of your choice then enabled on a per-project basis.

The Action Pack features 11 fully procedural sound effects models for popular action sounds, as well as 90 presets to choose from. These models are implemented as Blueprint-Spawnable classes that can generate sound effects in real time, completely procedurally. This allows fine-tuning of the sound effect at the source, which results in more immersive, more interactive, and more personalised audio.

Watch the demo here:

Each sound class offers various functions to change the parameters of the sound effect at runtime. In other words, the characteristics of the sound can be linked to any in-game events, which can lead to very organic and interesting results.

Any sound effect can be added to any element in your scene, instantly turning it into a procedural sound effect generator. You can then design your sound exactly how you want it, directly inside the editor. Our plugin supports spatialization, reverb, and all the other post-processing effects that a normal sound asset would support.

Included models: Explosion, Gunshot, Rifle, Helicopter, Jet, Propeller, Rocket, Alarm, Alert, Siren, Fire
