You got it, Kevin! Here is my fork on github where we can all work together on getting legal sounds that can ship with CDDA.
YOU can help by installing git, cloning the ChezzoSounds branch in my repository with the command:
Then go get sounds from one of the dozens of free sound websites. All these words are links to a different site with free sound effects. Or you can pull them out of public domain cartoons or movies or music. Or you can record them yourself!
Audacity is an awesome program for most OSes that I use for sound editing. Make sure you export in the ogg format, as it provides the smallest file size.
Add the sound in data/sound/ChestHole in the correct directory. Edit /data/sounds/ChestHole/soundset.json to point to your new file. (I just realized NONE of my new legal files are hooked up.)
Then change the file in data/sound/ChestHole/Attribution to give credit to whoever made the sound, like this:
Percy Duke //Name of creator
http://www.freesound.org/people/Percy%20Duke/sounds/23448/ //Website where you got the sound
/env/open_close/23448__percy-duke__door-creak-short.ogg //File name in data/sounds/ChestHole
Then submit a pull request to the ChezzoSounds branch, and I will put it in the set!
