Valve Acquires 3D Audio Company Impulsonic

You could say that I’m a big audiophile, and I love great audio tracks both in video games and outside of them. A new update from Valve is something to get excited about, that is if you’re into new audio technology.

The company recently introduced a 3D audio feature in Counter Strike: GO known as HRTF (or head-related transfer function). The feature has apparently been received well, as it’s made possible by Phonon 3D, tech built by Impulsonic.

Now, Valve has acquired Impulsonic, thus securing their use of that technology in their signature games.

Here’s a message from the Impulsonic team:

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.

    Will Valve use it to help make a new game? Probably not.

    this sounds like the kind of thing that don’t really make much for a long time until a game/feature/hardware/method comes out and actually uses it right and suddenly it becomes revolutionary
