Opening the zip of a bag, searching for something and closing the zip again ( a lot of things inside the bag: pill boxes, lip sticks, etc. ) there is also the sound of a hook-and-loop fastener.
Getting ready for my shower, fly unzipping and snap opening with the rustle of taking them off and dropping them on the bathroom floor. Iphone, external mike, audacity.
This is a very brief sample obtained by opening a zip file with audacity. It sound a bit like a dial-up modem. It seems to work well for melodic solos and playing two or three note chords sounds good, too.
This is actually the sound of me opening my little action camera 1st person camera's "briefcase" of parts and accessories for it, going through it a small bit and than closing it back up again.
This is a handbag zipper. First the zipper opening and then the zipper closing. I used zoom h4 handy recorder with built-in microphones. I modified the original sound and added equalized, compression and sound reduction. All with adobe audition 2014.
