Four tracks through a first-order ambisonic microphone, processed using SPARTA in Reaper and rendered to binaural:

Track 1: Wind in the trees. Ironwood tree to the left, palm tree to the right, creaky wooden fence to the right, crickets in front.

Track 2: Rocky beach, ~8-10m back from the water. Three people walk by, right to left, behind the mic.

Track 3: Rocky beach, ~5-8m back from the water. Birds in the trees on all sides.

Track 4: Rocky beach, ~2m from water on the sides. Walking in a circle jingling keys to test HF response and imaging.

An underwater recording of bubbles being emitted from sidewalk chalk as it's immersed in water. The hydrophone used is an early prototype of the Gladys hydrophone developed by Jules Ryckebusch and now available from JLI Electronics.

Sidewalk Chalk Bubbling Squealing Screaming Howling Underwater Tom B

Recording of ocean waves advancing onto and receeding off of a stony beach, made using a hydrophone buried in the stones. The hydrophone used for this is an early prototype of the Gladys hydrophone developed by Jules Ryckebusch and now available from JLI Electronics.

Ocean Waves On Coarse Sand Beach Gentle Periodic Buried Hydrophone Tom B

Underwater recording of the splash from a rock being tossed into a pond. The hydrophone used for this is an early prototype of the Gladys hydrophone developed by Jules Ryckebusch and now available from JLI Electronics.

Rock Splash In Pond Sploosh Tom B

Test session at the south end of Kiholo Bay using a custom built pseudo-SASS. Inadequate wind protection was used, so the track is compromised with wind noise. But the test of the microphone array worked out well.

Contact microphone recording of kite line scream

#150 Cored Dacron kite line
6' rokkaku kite
6kt variable wind
Piezo contact microphone attached to a carabiner that was part of the ground tackle
Tascam DR-70D

Vibrations from the ground tackle contaminate most of this recording, but there are more bass overtones in this than in the one with the mic attached to the kite line.

Kite Line Scream - Contact on Carabiner

IDCD 2016 

Not the best conditions for recording the dawn chorus. The rain began a little after 2am and didn't let up. The microphones were placed low to the forest floor, which essentially close-mic'ed the raindrops hitting the leaf mast. Koa leaves lie almost completely flat, so rain drops sound like they're hitting cardboard.
