Airfoil for Windows 3.5 With System Audio Capture

Airfoil for Windows IconIt’s time once again for an update to Airfoil for Windows, our audio streaming tool for Windows. We’re always working on improvements, and today, we’ve got a big one in the form of full System Audio capture. You can get that in the new version 3.5.1 Read on to learn more about Airfoil for Windows 3.5, or download it right from the Airfoil for Windows page, or by selecting “Check for Update” from within your current copy of Airfoil for Windows.

System Audio Capture

Last time around, we updated Airfoil’s Instant On component, to improve audio capture. Now, we’ve added an entirely new method of audio capture: System Audio capture. When you select System Audio in Airfoil’s Source menu, you’ll be able to capture all of the audio playing on your machine at once. This can be useful in its own right, but it’s also a great workaround for capturing audio from otherwise troublesome applications.

This improvement should be particularly welcomed by Windows 8 users. On Windows 8, several major applications can’t be captured due to the restrictive nature of the OS. With System Audio, you’ll get audio from those apps, and be able to stream it with Airfoil.

Using System Audio is a snap. When you select it the first time, you’ll be prompted to install the System Audio driver. After that, it’s just select System Audio from the Source menu, and click your desired outputs. Now all of your machine’s audio will flow out. Excellent!

Thanks to VB-Audio

The System Audio driver Airfoil uses is based on VB-Cable, from VB-Audio Software. The software is free, but we’ve made a donation to the developers to support its development. If you find the System Audio capture in Airfoil useful, you might like to show your thanks by donating as well.

There are plenty of other tweaks and fixes, so update your copy of Airfoil for Windows now!

  1. Unfortunately, System Audio capture is not available on Windows XP. We highly recommend all users update to a newer version of Windows.

P.S. A Note to Users of “Reemote for Airfoil”

As some folks will be able to discern, Airfoil Remote has evolved from a product called Reemote for Airfoil, by our colleague and friend Kai Aras of 010dev. We’ve acquired Reemote for Airfoil from Kai, and made Airfoil Remote a free update for previous purchasers.2 We hope you enjoy it! You’ll no longer need to use the Reemote Server on your Mac – it’s all built into Airfoil now.

If you have any questions, please contact us directly.

P.P.S. A Note to Airfoil for Windows Users

Airfoil Remote is not compatible with Airfoil for Windows. Yet.


  1. If you’re still on Mac OS X 10.6 or below, you’ll need the newest possible version for your OS, available from our Legacy page. Airfoil 4.7.5 on Mac OS X 10.6 will work with Airfoil Remote, but it will require running the “Reemote Server” application. See this page for details.

  2. Unfortunately, Apple has not made it possible to provide a free upgrade to the iPad-only Reemote for Airfoil HD. That product has been removed from the store (though existing customers can still download the last version). We encourage all iPad users to purchase Airfoil Remote, which is now universal.

An App Stories Interview

I was honored to take part in a quick interview with AppStories.org, a great collection of interviews with all manner of different Mac and iOS developers. App Stories is part of App Camp for Girls:

App Camp for Girls, a non-profit organization that seeks to address the gender imbalance among software developers by giving girls the chance to learn how to build apps, to be inspired by women instructors, and to get exposure to software development as a career.

It’s a great effort, and there’s still time to donate.
