Teensy 3.1 Audio Adapter Board - what microphone?

Hi @cartere, Thanks for the reply!
Do you happen to know if it's possible to use the amplified adafruit mic ? (http://www.adafruit.com/product/1063)
I believe there seems to be a problem because it's floating at around 1.6V. I assume you'll have to connect it to the Teensy's 3.3V pin.

Digging through the forums, I just found this post by Paul which suggests you have set the audio shield's input to AUDIO_INPUT_LINEIN instead of AUDIO_INPUT_MIC and then you can set the lineInLevel (to 3.12 Volt I assume. I don't see a 3.3V option)

If you connect it as line in, do you still have control of the gain ? Or is that can only be controlled by the hardware pot on the adafruit board ?

I might buy the mic you suggested in case this doesn't work.

I would think the adafruit amplified mic would "just work" with LINEIN. Adjust your input level with the pot on the mic board, perhaps using analyze_peak.
I hooked the adafruit board to the adc input on a teensy3.1 and it required the use of Paul's input network, using the mic on adc and a powered PC speaker on the dac output produced very useable audio.
