I've created >40 sounds from various binaries I discovered on my Ubuntu Studio machine at home. It was totally fascinating exploring these files in this way. Much of the sounds you find are basically white noise, but it is definitely possible to find snippets with interesting harmonic content. Here is the link to the pack: http://www.freesound.org/people/wjoojoo/packs/15674/
Hi wjoojoo. Which distro are you using? This file came from Mint (13+ possibly). I've since switched to Point and didn't save the original file. But thanks for your comment as I've forgotten how great these sound and will probably do some processing on them. All I can suggest is to get a livecd and search /var/cache/apt/srcpkgcache.bin. I'm sure you've figured that out already. I'm afraid I'm a Windows audio processor, but it would be interesting to hear it done in Linux with Audacity - let me know if you do. I'd do it myself, but I far too lazy to figure out the Jack stuff for a DAW in Linux. Sad :)
I've been doing this type of thing quite a bit recently with Audacity on linux, and haven't come across any files on my system that sound this rhythmic. Curious to know, what file is this exactly? I've been exploring binaries in /usr/bin and shared objects and archive files in /usr/lib and /usr/local/lib. Thanks for sharing!
