    Equipment Note

NOTES: Recorded simultaneously by Gerrit Vyn using 30"Roche parabola with MKH20. I used the filter on the Telinga Pro 5W stereo parabola from the beginning until 14:20. After the break at 14:20, I turned the filter off. This is easily visible on the waveform. First female vocalizations start at 28:43. They are high-pitched and more staccato than the male vocalizations.
