Interesting. One won't readily associate it with a frog. What is the background sound? Some kind of train?

Sabyasachi - It's a stream/waterfall, with some light rain. No trains around . We were close to a road, but there were no passing vehicles at the time of recording.
I have given up on trying to use high/low pass filters to isolate animal calls, because it almost always ends up cutting off the acoustic properties of the calls, especially if they are to be kept for further analysis.
