Dolby Atmos Mix for “404”

Octobre 2025

Dolby Atmos sound design and mixing for apocalyptic short film.

We brought the world in the short film “404” by River Sound Studio's in-house director Sean Wirz to life with immersive sound design. Drones, sirens, and mechs are not seen in this world marked by decay, but only heard.

The bombastic film music was also composed by Silvio Buchmeier specifically for our 7.1.4 setup.

A huge thank you to the amazing team:

Nadine Aeschbacher for the rough cut
Marlen Schmid for her support on set
Gabriel Noah Maurer for the performance
Pavlo Melnychenko for the VFX
Nicolas Minder for the grading
and Silvio Buchmeier for the magnificent music

Director and producer: Sean Wirz

In this sci-fi-inspired, improvisation-based short film, Gabriel-Noah finds himself in an endless loop. Every escape ends where it began. The world seems threatening and familiar at the same time. Is it a glimpse into a soulless future – or into a soulless future? And you, are you coming with us?
