Hi Im trying to get a teensy 4 and audio shield to make a recording guest book with recorded message out of an old telephone… but they are out of stock… does anyone know if the 3.2 or 3.5 would do the same job?

Hi @stevep789 and welcome to our forum.

I guess it should work, but for Teensy 3.x you would need TEENSY3_AUDIO. I think TEENSY4_AUDIO will not work.

Thank you.
