With the emergence of wonderful audio apps such as Audioboo, it has become a challenge to record outdoors without the rumbling from wind hitting the microphone.
If you get some nice fluffy textile (see my note DIY Wind-jammer for Zoom H1), you can use a similar, but even simpler approach.
Cut textile
Cut a piece of the fluffy textile about 2 centimeters wider than your phone and about twice the length of the “base” of the phone.
Fold and stitch
Fold the textile with the fluffy side in and sew/stitch along the short sides.

turn inside-out, attach to phone
Turn the textile inside-out (so it gets the fluffy side out!)
Put it on your phone and record.

Happy Recording!

(and similar audio recorders)

For casual professional recording of everyday sounds, ranging from nature to interviews, the Zoom H1 is a very convenient and inexpensive device. With outdoor recording, wind is almost always present in places like Ireland. If you use a H1 as it is, your recordings will rumble with every puff of wind and destroy your recording.
To remedy this, I initially bought a simple foam windshield and this was sufficient on calm days. But for the normal gusts of westerly winds we get in Ireland, the design had to be improved. Rycote are making Mini Windjammers that cost around £STG25.  As I know how windjammers work, I found the cost excessive and the Rycote design perhaps not the optimal solution.
Fluffy textile
I bought some nice fluffy/hairy textile in a local shop (Hickey’s). The criteria for the material was that the base material should be as transparent as possible and the outer coating as hairy as possible. As this was shortly after St Patrick’s day, I bought 2 meters of a green fluffy material for 5 euro (which is enough for perhaps 20 windjammers).
Wire cage
Next, I made a small cage from brass-wire, to contain the H1. You can use any kind of semi-rigid wire for this.

After shaping the wire-cage, I folded some fluffy textile around it with the inside out and marked where to cut the textile.

Fluffy textile sticthed together, and Velcro

I sewed the front of the textile in a curve to fit the front of the wire-cage, and along the bottom I stitched on some Velcro, which makes it easy to put the textile on on the cage and to get, for example, a headphone cable through.

Elastic cage
Finally, I used some elastic band to hang the Zoom H1 in the cage, to prevent handling noise and other unwanted vibrations to be picked up, and inserted the cage with the H1 into the green fluffy tube. Zip up the Velcro and you’re ready for recording.

Happy Recording!

A first sketch of a new custom controller.

  • Sliders fading up and down
  • Knobs for turning
  • Cranks for turning
  • Buttons for activation – perhaps with aftertouch (force sensitive)
  • Switches for turning things on or off.
  • Wheels for turning
  • Squishy things for squeezing

USB i/o, perhaps using OSC protocol.

Build in a flight case.

I’ve been using the excellent site and apps Audioboo for a couple of years. While other Audioboo makers provide stories, music, guiding, journalism or audio-blogs, I think all my Audioboo podcasts are SILENT.

This is an issue I’ve been thinking about for many years. In the mid-1960’s I read Heinrich Böll‘s story “Murke’s Collected Silences” and at that time I was fiddling with reel-to-reel tape-recorders, microphones, and in general exploring different perspectives of sound. Inspiration!

There are so many different forms of silence. A silence can be really quiet and peaceful, it can be really loud (I consider this silence as well, as you can’t have any purposeful or useful communication).

My Audioboos are available at the Audioboo site, and now also via iTunes podcasts.

Enjoy the silences!

During the Sounding Object project, we researched and developed new approaches for sound on computers, responsive to physical interaction and easily matched to physical objects. One of the demos was the Vodhran, a virtual Irish Bodhran drum. The performers gestures are tracked using a Polhemus Fastrak 6-DOF electromagnetic tracker in realtime and the sound synthesized in real-time by our sound object models.


This summer, I’m planning to make another version of this, probably the Hodhran – a Hyper-bodhran, using a real bodhran, parts of a Wii controller, an Arduino and a few sensors (such as force sensitive resistors and bend sensors).

This summer I’m planning to develop a number of new sound object primitives that I can use both in Softday performances and in sonic interaction design. The basic idea is there are three fundamental classes:

  • Impact
  • Deformation
  • Friction

I’m sure that there will be many exceptions to these classes, but when I look at many of the pd-patches I’ve created over the past eight years, I think it may be possible to use this approach, where parameters define things like the material being deformed, the flow of the action (gesture), etc.
