Physics-based audio for video games and virtual reality

Greetings from Impulsonic HQ!

We haven’t been super-active on our blog or Twitter lately, and some of you have been wondering what we’ve been up to. Well, today, we’re excited to finally announce that Impulsonic has been acquired by Valve! We’re confident that with the resources and expertise that Valve brings to the table, we will be able to push Phonon and VR Audio to an exciting new level. The Impulsonic team will be transitioning to Valve HQ over the coming weeks, but our work will continue uninterrupted.

For those of you who are already using Phonon, there is nothing you need to do at this point.

We wish to thank all of the users and beta-testers who have helped us bring Phonon and VR Audio this far; we hope you will continue to support us as we begin the next stage of our journey. We’ll have more to announce soon.


The Impulsonic Team.
