I am currently conducting some experimentation in ultrasonic recordings,
This is a field in which the medical industry is very advanced. However in the audio industry is very limited.
For not many good reasons aswell, as an audio geek I love the prospect of hearing things outwith our domain of hearing. The amount academic literature on recording ultrasonics is very minimal even though recording ultrasonics is reachable with minimal equipment. I hope to be recording ultrasonics within the next couple of weeks once I have built a new microphone to do this, thanks to http://www.wildlife-sound.org/equipment/technote/micdesigns/index.html wildlife sounds guide to building budget ultrasonic microphones.
I will be posting the results here soon , and I hope you guys are as fascinated by ultrasonics as i am .
I would like to give my thanks to the wildlife recording society due to their journals having a large amount of research into ultrasonic recordings which has been extremely helpful for my educational and professional learning recently.
