Hi,
I want to build an usb microphone to use on my pc for remote working and podcast recording. If could definitively buy a blue yeti or any streaming microphone but I would not learn much from this.
Where I start from :
-I can solder SMDs, and work wood (and somehow metal)
-I can use kicad and already hade some PCB manufactured for me, but all digital, I come from a software / computer background and don't now much about analog electronic
I've seen this video that seems rather close to what I hade in mind : Building a quality USB-C microphone - YouTube . I have a few questions :
- should I replace the noname usb adc with e.g. a TI PCM2912A or wouldn't it change anything soundwise ?https://www.ti.com/product/PCM2912A
- the video uses a THAT1512 but that5522 or TI INA849 seems to be newer / better SNR version. Any reason not to use them ?
- he uses a jli-2555 capsule. Is there any close quality capsule I could buy from aliexpress (the $13 jil233 will probably cost about $45 once i've paid shipping, vat and custom fees. Buying on aliexpress I can have almost free shipping shipping and pay the VAT directly so I won't have custom fees)
Thank you,
windless

I found that a Shure lapel mic sounded the best when I made a recording of myself speaking. That may be better than a "studio" mic if you don't have an acoustically-treated soundproof studio.
If you want to make an interface for a common electret mic capsule, this page looks helpful:
