Hi everyone,

I'm kind of new in using the teensy, but I'm trying to record sound (.wav) with my teensy 4.1 using the audio shield 4.x. I have the MAX9814 microphone anplifier, but I don't know how to connect this to the audio shield. The tutorials that I found were all old versions of the shield.
 
Hello and welcome,

You can hook that to the line input of the Teensy Audio Shield (Header pins). You'll need a blocking capacitor between it. And you can adjust the gain/attack/release as detailed on the adafruit project page.
