Sounds of bats exiting a roost. Recorded with a Zoom H1 linked by jack to jack to a Magenta Bat 4 heterodyne bat detector. Each cluster of sounds is a bat leaving the roost. I have clipped out the major gaps. I think there are 12 bats recorded here. 30 left the roost in about 10 minutes. This group were recorded at about 35kHz.

Bats exit roost at MS 8-9-12

This is a recording of a replica Iron Age Bronze Horn being played by Billy MagFhloinn inside Oweynagat (Cave of the Cats) near Rathcroghan, County Roscommon,  on 4 Nov 2012.
This is only a sample of the range or sounds that can be achieved on such a horn. Shared here for those who heard it live on the day.

Recorded with a Zoom H1.
