Where we give the mic to nature and amplify Earth

Hear the Earth You're Missing

Threshold Shift is a collection of field recordings created and contributed by sound professionals, scientists, and student-citizens from across the globe. Why do we record? In part, because sounds are disappearing faster than we can capture them. By many accounts, there is less than 2% of the Earth that is free from human-induced sounds and that area is shrinking quickly. Perhaps, as we sit silently with our recorders, we are trying to hear the heartbeat of the Earth. Or maybe we just simply want to spend more time in a quiet moment away from the constant bustle of other humans. In any event, by creating these sonic trails, we hope to understand who and where we are as a planet, how we got here, and where we might be headed in our shared future. We have attempted to leave these field recordings as raw and uninterrupted as possible to allow people to hear these places the way the recorder did. By sharing these sonic treasures with our listeners, it is our hope that this series will increase awareness about acoustic ecology, bioacoustics, and sound preservation efforts as well as create some room in an otherwise human-crowded media landscape for nature to have some air time.

Every 5th Saturday of the 2018 from 12-3 am. Long form episodes of immersive soundscape goodness. 

Past episodes aired Fridays at 10:00-10:15am from Sept 1- Oct 27, 2017 as a feature of KBOO's 2017 Sound Artist in Residence Program.

Recording Note:  Unless otherwise indicated, all episode intro and outro soundscapes are recorded by Nikki Martin using a Zoom H2 or Sound Devices 702.
