Nemisindo launches procedural audio plugins for Unreal Engine

Nemisindo is a spin-out company from our research group, offering sound design services based around procedural audio technology. Back in August we blogged about the launch of Nemisindo’s online service at https://nemisindo.com . Now, Nemisindo has a new launch, targeted specifically at game developers.

The Nemisindo team is pleased to introduce fully procedural audio plugins for Unreal Engine: the Nemisindo Action Pack. Nemisindo have brought our state-of-the-art models to Epic Games’ renowned game engine, enabling true procedural sound effects generation within Unreal projects.

Procedural audio refers to the real-time synthesis of sounds depending on specific input parameters. Much like how a landscape can be procedurally generated based on certain inputs, like “elevation”, “variation”, or “biome type”, a helicopter sound can be procedurally generated based on parameters like “rotor speed”, “engine volume”, or “blade length”. Procedural audio is the next generation of sound technology that creates realistic immersive soundscapes that are fully interactive, adaptive and dynamic.

The Nemisindo Action Pack includes 11 different sound classes: Explosion, Gunshot, Rifle, Helicopter, Jet, Propeller, Rocket, Alarm, Alert, Siren, and Fire. Each sound class can generate audio in real-time, and, for comes with built-in presets for popular settings (such as ‘bomb’ and ‘thud’ for the Explosion model, or ‘emergency vehicle horn’ for the Siren model). The Nemisondo Action Pack plugin enables Unreal developers to:

  • Design sound exactly how you want it – directly inside the Unreal Editor
  • Link model parameters to in-game events via Blueprints
  • Add any model to any actor, instantly turning the actor  into a sound generator
  • Easily implement adaptive audio without external software dependencies
  • Reduce disk space with zero-reliance on sound samples

The Nemisindo Action Pack is available in the Unreal Marketplace at:

And here’s a short video introducing the Action Pack and its features:

There’s another great video about it by The Sound Effects Guy here (we don’t know him personally and didn’t pay him for it or anything like that),

Nemisindo’s mission is to generate any sound effect procedurally, doing away with the need for sample libraries. Nemisindo’s technology can generate entire auditory worlds, create soundscapes based on sounds that have never been heard before, or enable every object in a VR/AR world to generate sounds that can adapt to changing conditions. These sound effects can also be shaped and crafted at the point of creation rather than via post-processing, breaking through the limitations of sampled sounds.

Named after the Zulu for “sounds/noise”, Nemisindo is an Epic MegaGrant recipient, awarded to support their contribution to procedural audio in the Unreal community.
