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

We used to call it the apple problem. 🍎 If you want to see how SweejTech Propagation works in your project, reach out to [email protected]. If you just want to chat, join our Discord: discord.gg/SA992rJ7G

We found the SweejSpot! Bird sounds on trees, rattling windows after explosions, automatic forest detection, contextual ScatterSpot placement. One system, endless possibilities.

As the year winds down, we wanted to showcase a few new unannounced technologies alongside fresh updates to our announced work. Including industry-first Spectral HDR, the next stage of our GPU-driven obstruction system, evolving into a full acoustics solution, our super-fast sound-centric worldised reverb, and a handful of other new technologies we’re excited to share. Everything here comes back to our core aim: letting sound designers focus their energy on creating great audio, not wrestling with workflow or worrying about performance. Highly optimised at runtime, plug-and-play at authoring, and always built to stay out of your way. You can try all the technologies now for free for 3 months, with all license information available here sweej.tech/license/ reach out to us directly by emailing [email protected] for any questions

The roster keeps growing! Grab us at GameSoundCon or reach out to [email protected] if you want to hear more.

With Static Mode and the HDR Toolbar, HDR now adapts to your workflow, supporting classic narrative and traditional mixing while retaining dynamic power. Check out the video for more information, or visit the blog for some examples on how this works sweej.tech/blog/2025-hdr-sta…
