Sound triggering
Is there any update on the sound triggering. The ultrasound background can be very quiet except for a few intermittent bat calls. Is it possible to "monitor" and record only when the sound level in a tunable frequency or frequency range exceeds a specific intensity value. A prebuffer could be useful too in this case.

Thank you for the sound trigger system. In general it seems to work quite nicely on completely calm nights with high filter set at 15kHz and 196, 250 and 384 samplings a good balance is found at a amplitude level of ~120-130. At low amplitudes below 80 intrumental effects create false alarms and trigger is not effective any more. I am quite satisfied, thanks for the wole team!
