Having got my Wolfson Audio card working happily with a Raspberry Pi 2, I decided to try and check the frequency response.
As this card is described as a 'audio card' and the only figures I've seen relate to the audible range, I didn't have high expectations regarding its use in my Bat Call Logger.
Anyway, to find the answer, it was just a question of setting up some test gear and running a few checks.
