Sound Activated Recording

I’m experimenting with sound activated recording using SoX….no hours of silence in the recorded files – just bat calls 🙂

Here’s a photo of my waterproof microphone – an electret poking out of the bottom of a small funnel which is wrapped in cling film, and sealed using self-amalgamating tape. The cling film doesn’t seem to make any noticeable difference to the recordings.
