Even without middleware, Unreal Engine’s blueprint system provides the tools necessary for complex audio gymnastics. In this video, Tzvi Sherman demonstrates procedural, spatial, and dynamic sound design. From core basics like adding ambience to a scene through asynchronous looping 2D layers as well as randomized and modulated one-shots to more advanced techniques like controlling audio playback through Blueprints – the sky is truly the limit. If you’d like to follow along or give this a shot yourself, Tzvi uses Epic’s free Action RPG game asset available in the Unreal Marketplace.

Bonus: Learn what you can do with a middleware solution such as Wwise
For this example of what’s possible in Wwise, Unity’s 3DGameKit asset package is used to show some of Wwise’s integration scripts, like AkAmbient and AkRoomPortals, as well as functions you can use within Wwise itself without needing to touch code. Covering basics like Random, Blend, and Sequence Containers as well as game parameters like Switches, States, and Real-Time Parameter Controls (RTPCs), this video shows an overview of how, as the sound designer, you can take control of implementation and further your creative realization by creating an immersive, in-game world through Attenuation Sharesets and complex 3D Positioning.

EXCITED OBJECTS is a sound library of rather abrasive metal textures recorded using metal objects and a surface transducer, recorded with contact microphone and guitar pickup.
Synthetic sources such as sinewaves and noisy, stochastic waveforms were routed to the transducer and is exciting objects such as long springs, pieces of scrap metal, a prepared mini-guitar and a cheese grater.
Some seperately, some in combination.The library is provided in 96kHz/24bit with UCS filenames and relevant metadata.
