BatGuru: a British bat ID helper

My BatGuru is a program written in Gambas which helps me identify British bat species based upon echolocation call data.

It simply saves me having to juggle the key parameters in my head as I scan the charts in my reference book.

But identifying bats from their calls is tricky due to the wide variability of their calls.

Bat Call Analysis: second thoughts

I'm still trying to reconcile my bat call recordings with the data provided in the Jon Russ book "British Bat Calls".

This caused me to question whether my home-brew bat detector was a reliable witness.

Just how much faith can I have that my FD detector is producing sensible recordings?

Bat Call Analysis: more difficult than it looks!

So I've now got a few hundred recordings from my Bat Logger, collected over a number of nights.

Time to settle down with Audacity and a pint of IPA, and analyse a bunch of waveforms.

Identifying the bat in question is easy, right? Its just a matter of determining frequency, repetition rate...
