Where can I find old cyanogenmod notification sounds?

I recently had to reflash my phone. And am now missing my old default notification sounds. I originally flashed CM10 and later upgraded to CM11. Now I wiped the phone and CM11 directly. In this new installation I am missing the notification sounds I used before (namely something like "cm-chime" and "cm-prechime"). How can I get them back? 1. Is there a repository on the internet, where I could download them? 2. Where in the ClockworkMod backup I made before wiping are the notification sounds stored?
