A variation on BeamformX called DroneHound has been posted www.optinav.info/ftp.html Sounds are shown in the display as open circles if they are not classified as drones or angry red drone shapes if they are. The tabular results give the bearing, overall sound pressure level, and "drone metric" of sightings that are classified as drones. The classification threshold for the drone metric can adjusted in the Settings dialog. Most of the controls are simplified relative to BeamformX. Fisheye mode in the Camera dialog is recommended. The frequency should usually be set to about 4 kHz. The posted version, 0.001, is untested and should be viewed as a rough draft.
