Hi thanks for getting back to me, as that is only the minimum trigger duration I end up having recordings of varying lengths which makes analysis hard. Am I right in saying if you have an amplitude threshold you can't then split files? None of the recordings I have seem to get recognised by the split function if I have used an amplitude threshold (even if the recordings are 10+seconds)

I think essentially what I'm asking is whether you can have a maximum recording length when the amplitude threshold is reached or whether there is a way to to split recordings into 1 second files.
