*Updated* Airfoil for Windows 2.6.1 Arrives

Airfoil for Windows IconAs mentioned earlier, Airfoil for Windows has been largely re-coded, moving from Win32, to .NET. Our goal here was to make it easier to maintain for the future, provide greater productivity on our end, and make it more versatile overall.

This update also features improved compatibility with applications like foobar2000 and others and better synchronization with all output types. Airfoil for Windows 2.6.1 is a free update for all licensed owners of Airfoil for Windows, and can be downloaded right here. Windows 2000 users should note that Airfoil 2.6.1 requires Windows XP or Windows Vista.

If you’re not currently using Airfoil (for Windows or Mac), you can learn more about our tool for sending any audio to the AirPort Express, Apple TV, and other computers on the Airfoil page.

Update (August 14th, 2008): While in development, Airfoil had an expiration date in the code, so we wouldn’t have old copies in the wild. It looks like this wasn’t properly disabled in Airfoil for Windows 2.6, preventing the software from working past August 31st, 2008. Updating to Airfoil for Windows 2.6.1 fixes this issue, so grab the latest version right here.

    Windows 2.6? Am I going to have to downgrade by machine from Windows 3.1 to use this? :-)

  2. Quentin Carnicelli says:

    Hey with everyone downgrading from Vista to XP, going backwards is the new cool thing.

  3. AJM says:

    Why am I getting “This development copy has expired” message??????

  4. Paul Kafasis says:

    AJM, first up, be sure to grab 2.6.1 right away.

    But also, check out your system clock – expirations shouldn’t be happening until September 2008. Is your clock a month fast?

    Anyhow, grab 2.6.1 and you’ll be all set.

    I have been looking for this app for two or three years, where have you been hiding it?

    The current version does not work with Airfoil Speakers for linux — complains of a version mismatch. Major problem for me as only one of my stereos is connected to an Airport Express, everything else us hung off linux boxes.

    One other very annoying (occasionally painful) thing is that Airfoil does not remember the volumes settings. The Airport Express is connected straight into an amp with NO volume control. It’s awfully loud when it connects at full volume – can’t set auto-connect because of this.

  6. Bill Smithem says:

    Duh! Just got round to reading the notice that you didn’t do the linux port. Sorry.

  7. David Hammerton says:

    Hi Bill,

    Thanks for pointing out the Linux issue. We’ve now updated Airfoil Speakers for Linux to work with the latest version of Airfoil. You can download the update here:


    Please let us know via the support page (http://rogueamoeba.com/support/supportRequest.php) if you have any other issue.


  8. Paul Kafasis says:

    Bill: We definitely DID do the Linux port, it’s just not officially supported. That says, as David noted, it should be all set now, and work fine with Airfoil for Windows (and Airfoil for Mac). Just grab the latest version from the link provided.

    As for volume settings, we’ll take a look at this and see what’s up. Stay tuned for updates to Airfoil for Windows.

    And of course, thanks for the feedback, it’s been very helpful!

    Hi all — does this version load code into every single process image via a new mechanism? If you are using HKLM\SYSTEM\KERNEL\InjectDLL, *many* rootkit detectors and games like World of Warcraft and many other programs that ensure they are running without modification will fail.

    Hoping the rewrite isn’t the .NET way of using injectDLL :)

  10. Mr. Make Believe says:

    Hi there,

    Are you considering making Airfoil run on the .NET compact Framework in the future?

    With the large capacity wifi enabled handheld media players available these days, wouldn´t it be great to stream music straight from your handheld to the Airport express using Airfoil? You have the ultimate remote control media library in the palm of your hand. Nobody understands why Apple didn´t make the iPhone and the touch compatible with the Airport Express, but with airfoil this need feature would become available for Windows CE/Mobile based media players.

    I know I asked this kind of question before, but since there isn´t a descent way to fulfil my wish I focus my hope on Rogue Amoeba.

    Hi Martin,

    Airfoil uses two hijacking techniques. The primary technique is to hijack applications at startup and inject our own DLL in after creating the process. This ensures that only the process that you wish to hijack is actually hijacked, so no rootkit or cheat detectors should pick it up.

    The other technique, which is disabled by default, is Instant Hijack. Instant Hijack injects our hijacker DLL to every application using the HKLM\Software\Microsoft\Windows NT\CurrentVersion\Windows\AppInit_DLLs registry key. This method may be picked up by such detectors. If you find this is happening, you can easily disable it in the Airfoil preferences menu.
