Free Teufelsberg NSA listening tower impulse responses

Balance Mastering Teufelsberg impulse response pack.

Amidst increasing concern about data privacy and how our personal data is being handled we bring you a bit of sonic surveillance history: a set of reverb impulse responses allowing you to use the acoustics of the main listening tower at the former NSA compound, Teufelsberg, in your own productions. Prior to the fall of the Berlin wall the compound was run by the American and British military with the main objective being to intercept and process any Soviet and Eastern Bloc communications as part of the ECHELON intelligence gathering network. You can find some excellent historical information in the links below, including a micro-documentary made by Vice in 2010.

We've recorded the impulse responses with great care and mastered them to be useful in a wide variety of situations. There are six (quite different) variations to experiment with and apply to your source audio. Finding an opportunity to approach the towers and record the impulses was tough, not to mention having to climb and squeeze through a tiny gap to reach the uppermost tower, so we hope you enjoy incorporating a piece of Cold War history into your music and audio productions.

Unfamiliar with convolution and impulse responses?

This 2005 Sound On Sound article explains convolution and using IRs not just for reverbs which is the standard use but for other processes too.

Or you could just get stuck in with a convolution plugin native to your system.

Free option

If you find that your DAW doesn’t have a native convolution reverb plugin you can use a third party plugin to load these such as these ones.

Best option

For us, Liquidsonics provide the best option(s). Both of the following are cross platform plugins and offer true stereo convolution at zero latency.

Help us help you

We’ve spent a lot of time and effort on these IRs. These weren’t just set and forget sweep recordings, they’re the result of many hours of critical listening and tweaking both on location and back in the studio. We’re hoping to create more useful tools like this to help you make great sounding mixes, quickly and efficiently.

If you use this IR set and would like us to create more like it, here’s how you can help:

  1. Try our mastering service
    Send us a track and we’ll make you up a free sample.
  2. Tell a friend about these IRs
    Either online via forum post, sharing socially…

    …email or just plain face to face chat.
  3. Support our social channels
    Like us on Facebook, follow us on Twitter & Soundcloud.

Finally. Remember. Like anything involving convolution, you don’t have to use these IRs as intended. Use them in productions as a standard reverb if you want to. Reverse them, mangle them, distort them; these are just a starting point.
