Hi all,

I'm working on a project which needs a microphone input. For prototyping, the tiny electret condenser that's recommended for Teensy worked fine, but now I need something with higher audio quality, better rejection, etc. I'm using Teensy 4.0 with the Audio Shield.

I'm fully prepared to cannibalize a "real" microphone, and it seems like my options are as follows:

- use an analog mic, then use an amplifier to bring it up to line level for Teensy's line in
- use an analog mic, then use an ADC to translate it for i2s input
- use a digital/USB mic, and somehow feed that into i2s

Would anyone be able to point me in the right direction here? Surely I'm not the first to need a beefier microphone with Teensy, but I'm having trouble finding other threads on the topic. Any suggestions would be much appreciated!
