Hey guys!
New to the forum but have been reading for quite a while, so first of all thanks for being awesome both by sharing knowledge and maintaining a nice community.
It's super inspirational and has given alot of confidence into try building something for myself.
Background:
I work as a sound designer and composer in the film and gaming industry. Recording for this purpose usually entails alot of non-traditional recording and out of the box approach. Something in particular that is useful is ultrasonic recordings done with 192 kHz or more samplerate, which utilizes the fact that some mics (most mics, but some way better than others) record above audible hearing. Basically the idea is that you pitch these frequencies down to hearing range while still adhering to the nyquist-shannon theorem, aka create clean sounding source material allthough it's pitched down as much as 3-4 octaves. Add some effects / sampling magic and get sofa king creative results.
Thread topic:
How would you go about building a good sounding DIY ultrasonic microphone, and what would be the most important things to think about in your view?
Example could be:
What capsule and why?
What in the circuit should one pay special attention to?
Have you done any experimentation on your own in this scenario that you'd like to share?
Already existing mics:
Examples of mics I've had good results with are: SDC: Micbooster/LOM mics with Primo capsules, Sennheiser 8000 series (goes to about 60kHz). LDC: Ehrlund-M (goes to about 87kHz) and obviously the Sanken CO-100k which goes to +100kHz and is heavily marketed for purposes like this. There's also a bunch of measurement mics and what not that goes to 300+ kHz, but in my experience dont necessarily sound good for sound design.
It would be interesting to hear your thoughts, and hopefully excite you to ponder a more out of the box scenario.
Cheers
