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 hello@sweej.tech for any questions
