DIY, Interference Tubes, Shotgun Mics, Sound Design in News, Projects Monday, June 11, 2012 at 12:09PM A standard shotgun microphone is essentially just a microphone capsule and an interference tube. The capsules are simple enough, it's these interference tubes that are (apparently) complicated. An interference tube is a tube with slots cut into it to cancel out any sound coming from off axis. Any sound coming from on axis (straight down the shotgun tube) will hit the microphone without any interference ie the loudest sound. Any sound coming from off-axis will encounter the slots and bounce around in the tube until they are cancelled out with each other or attenuated down to nothing (inverse-square law). The pattern of slots on the tube can vary, depending on the amount of rejection wanted, and the effects on different frequencies. Also, generally speaking, the longer the interference tube, the better the off-axis rejection (more directionality). So I decided, why not make my own interference tube and save a bunch of money? I did a whole lot of research on the web, and was surprised to that no one had tried this. At least, no one had documented trying this, maybe it was so complicated that they failed and didn't bother posting their results online. Well I hope to change all that.
DIY, Interference Tubes, Shotgun Mics, Sound Design in News, Projects Friday, February 3, 2012 at 8:28AM For the past few months I've been experimenting with building and using Inductors as audio pickups. An inductor is essentially a coil of wire, and when used as an input on a sound recorder, it picks up any EM waves nearby. You can use it to listen to your computers clock speed, the buzz of mains power, or do some really interesting things with magnets like what I've done.
Thursday, June 2, 2011 at 5:58AM Well I've finally done it. I've gone with a new layout, hopefully this one will be a little easier to navigate around. I'm still looking for someone to redesign my logo though, and for the time being I've removed the orange ladybug from the top banner.

Spring break is nearly here, and I'd really like to expand my website to it's fullest potential. Expect many changes in the near future...
