I was recording with audacity on my blue yeti whilst in my room. The mic was totally unbalanced on my bed and it eventually fell over but when i played it back it sounded like a nice whoosh or poof. Also if you put it in reverse it sounds like a giant wind flap like a bird or something.
Skewer slam is a combination of my knife sharpening sounds and metallic impacts/wobblers (some not yet uploaded here!) to create a sesnsation of something big, intense and lethal coming towards whoever it either find offensive or is ambulatory. As a personal note; the distortion you hear is not because of clipping in the initial recording but because of the higher acoutistic resonance and limiters applied which will not sound like this when downloaded.
This sound was recorded at the campus of poblenou of the pompeu fabra university, in the area of tallers in the corridor a-b. It was recorded between 14:00-14:20 with a zoom h2 recorder. The sound consist in percussive and low-mid frequency sound produced by the whole pencil case falling and impacting into the floor.
