A single bowling pin my local bowling ally got me for my birthday getting knocked on the ground of my room. Recorded and processed in audacity (headset mic).
After hours of searching for the sound of a guitar hitting the ground, i resolved to just recording a quick piece. This is a small sized guitar hitting the ground a couple times on a carpeted floor (recorded in logic pro).
Stereo recording of raindrops dripping off the roof and hitting the grass, with distant traffic. Recorded with a rode stereo videomic x into the sound devices mixpre-3.
