SweejTech Propagation works everything out at runtime. There is no bake step or pre-computation pass. When things in your game move, gets destroyed, or is built by the player, the system adapts automatically. #GameAudio #UnrealEngine #Wwise

SweejTech @sweej.tech · 11/09/2026

Congratulations to everyone at @BULKHEAD on getting #WARDOGS into Early Access. 100 players, three teams and a map that keeps falling apart around them is about as honest a test of audio tech as exists, and we're proud SweejTech is running in it. #gameaudio #unrealengine

SweejTech @sweej.tech · 07/09/2026

Question we get a lot: does this work if you're already on Wwise or FMOD? Yes. SweejTech Propagation runs alongside native UE5 audio or any middleware. It calculates obstruction and gives you the value. What plays the sound and how the value affects that is up to you.

SweejTech @sweej.tech · 24/08/2026

You can learn more about it (including how it works with middleware) by checking out the documentation here docs.sweej.tech/ueplugins/pr...

It's available now as part of the SweejTech license, and the overview video below covers the whole system in ten minutes. For an evaluation copy, reach out at sweej.tech or come say hi in our Discord.

SweejTech @sweej.tech · 24/08/2026

Propagation traces rays between spheres around the source and listener instead, giving your title a detailed, continuous result with the power of the GPU behind you, plus full control over how each sound responds: filtering, attenuation, curves and smoothing.

100

SweejTech @sweej.tech · 24/08/2026

Obstruction has traditionally been a binary affair. A single ray either hits something or it doesn't, so your sound is either blocked or it isn't, regardless of whether the object in the way is a building or a streetlight.

SweejTech @sweej.tech · 10/04/2026

Rather than juggling separate systems, everything (loudness prioritisation, attack and release ballistics, HDR modes, and culling), lives in one place. A shared decibel domain that feels natural and transparent from the moment you start working in it.

100

SweejTech @sweej.tech · 10/04/2026

Alongside the updated docs, a suite of videos is being released. We've just uploaded our HDR series, an overview of how our implementation brings HDR mixing, auditioning, and optimisation into a single, cohesive workflow.
