Spending some time in Georgia and have been blown away at the level of bat activity and diversity once you’re out of the cities. Have got so much data to review once I get home. BTO pipeline classifiers are proving invaluable when a single night produces 29gb and 8000 files of 🦇 recordings.

New look and new name for "pipistrelle" iPhone app. Next release will be renamed "pippyg" to reflect the obsolescence of original pipistrelle detectors. New "BAT filter" / BATS" modes which selectively apply strong high-pass filtering in bat mode, suppressing speech and bird call bycatch.

If you have built your own pippyg static bat detectors you might want to try out this new firmware. It makes chirping much more reliable in the presence of noise and interference. No changes to the chirping app, just the firmware. drive.google.com/file/d/1xdqS...
