My sister's shredding papers with her electric paper shredder and watching the morning news on tv at the same time. I recorded this with my lenovo laptop's built-in microphone.
I've recorded several variations of piano riffs, but left in the 4 best ones. It was difficult for me to remove the key tapping, so i left some key tapping alone at the end, if you want to try to remove it from the riffs.
Sound effect of paper index cards being torn, by hand, with multiple performances at different speeds and intensities. Recorded on a neumann kmr 81i into high-end studio preamps. Trimmed in pro tools with a gentle high pass filter, no other effects added.
