It's using a cheap (0.40c) sound card, but personally I choose to have high quality mics (primo em272 mic capsules, used in high quality parabolic systems.
However, there's nothing to stop you using < 10.00 euro microphones.
- hcfman 2y agoCheckout how good the primo mics are here for example: https://acousticnature.com/journal/how-to-make-diy-microphone-with-em172-272-capsules https://acousticnature.com/journal/how-to-make-diy-microphon...
- hcfman 2y agosbts-aru writes the files to an SD card so you don't need a whole running windows for this. Also, it passes all the audio through real time jackd, so while it's writing files you can also have an addition consumer running a real time matchin algorithm on it. If you use a Pi 4 or 5 you would be able to also do that at the same time on the same Pi as is recording.
