Parabolic microphone shroud w/ bluetooth
thingiverse
Project requirements: 1x Parabolic shroud 1x Jabra Classic Headset 1x Smartphone, Bluetooth recorder or equivalent 1x Sense of adventure Optional: Foam to place in front of microphone See update below. We have a printable parabolic microphone case type device for a Jabra Bluetooth headset that I acquired some time ago. You will need to dismantle the case for this project. Photos are included and details listed of how to obtain the correct shape we're looking for. The mic will swivel in place for precise focal adjustment. It's all about mathematically accurate, within a few hundredths of a mm in the file. It works quite well at its purpose as a directional amplifier. The theory was there so I created this. Some audio samples should be available soon. UPDATE: While this project was an idea, the practice proved to be something I couldn't quite manage with my limited time. An uninterrupted block of time later, I've realized that you can't route the audio from the mic to the headset using their implementation of some small QFP and Bluetooth protocols. So... it's necessary to use software to interact with the Bluetooth directly and either reroute the signals from mic to phone back to headset, which is convoluted to say the least, or you have to record the audio you're hoping to catch directly and forgo live feedback. 11/22/17 At this point, I don't have a method for real-time audio, I'm sorry. If anyone has any ideas to eliminate the lag that would be present doing it the straightforward way, let me know. If you don't need high-quality audio recordings from a distance or any feedback whatsoever, this device is perfect!
