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 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 the textile with the fluffy side in and sew/stitch along the short sides.
Turn the textile inside-out (so it gets the fluffy side out!)
Put it on your phone and record.
Happy Recording!
