Licensing Rogue Amoeba’s Audio Capture Technology

Over the years, we’ve received numerous requests from other businesses looking to license our audio capturing technology. Until now, we always declined these offers, preferring to focus on improving both the technology and our own applications which use it.

Recently, however, we revisited the possibility of licensing. Our audio capture code has been continuously improved for over a decade, and it’s now incredibly reliable. This technology is used by tens of thousands of our users every day, in Airfoil, Audio Hijack, Loopback, and Piezo. We’re tremendously confident in what we’ve built.

Because of this, we’re now pleased to announce licensing opportunities for our audio capture technology, ACE.1 ACE makes it possible for Mac apps to capture audio from one or more individual processes, as well as all audio from the entire system at once. The same power which drives some of our biggest apps is now available to outside developers as well.

If you develop an application which could benefit from audio capture2, please see our new licensing page, then get in touch!


  1. ACE has had multiple names over the years, starting with “Instant Hijack” and then “Instant On”. This newest name is intended to better convey the many uses of our licensable framework. ↩︎

  2. Examples include apps dedicated to screen sharing, VNC/remote access, game streaming, and more. ↩︎
