I'm also interested in the topic but I would like to record well over 100k. :-)
?
I recently had the opportunity to record sounds from . According to the inventor, some of the instruments produce sounds in the ultrasonic range up to 500 kHz and that the ultrasonic sounds have a positive effect on the audible frequency range. I asked how this was measured and was told that an was used to study the sound characteristics of the stone instruments. It was confirmed that the sound of some instruments was reliably measured up to about 200 kHz and beyond.

I don't want to hijack this thread, but I would like to ask two questions.
I would like to give it a try to record the stone instrument with ultrasonic mics.
Is it feasible as a hobbyist to build a low-noise, high-sensitivity microphone to record in the audible and ultrasonic range well above 100k? Are there any instructions for building a SimpleP48Ultra maybe?!?!
Has anyone tried the Dodotronic USB Ultramics which seem to record up to 384k?

I found the following articles by Zach Poff interesting:

Learning more about building ultrasonic microphones, I posted a while ago about ultrasonic electret mics. I've found the advantages of them for sure, being nice and easy. learning more and more though, I'm looking for something that gets up to 100k, like the oh-so expensive Sanken CO-100k. I've measured up to 40k on the electret mics that i'm using, which is very nice. but I want more. does anyone offer capsules that have that sort of response? If not, what are the other options for achieving this high of a response? Is the only option to build them myself? As a sound designer, I'm looking to capture the largest amount of frequencies possible.?
Thank you again, you incredibly knowledgeable people!?
