This is an edited version of "161977__gadiraz__metal-bed-spring-neumann-rsm191-gadiraz_". I used this version in my short film here https://www. Youtube. Com/watch?v=l9vovhdli70&t;=2s.
Spinning a 3 inch diameter x 1/8 inch thick aluminum disc on a linoleum table. Recorded in mono with an edirol r44 recorder and a shure sm81 microphone.
Turning of handle on metal spice grinder. Sound recorded using mono microphone and ensemble. Edited using logic pro time and pitch machine to speed up sound.
This was created as the sound of bullets hitting robots. I dropped coins on a music stand and then pitch shifted them. Oktava 012 microphone through neve preamp and apogee mini-me a/d.
