* Introduce Sounds: the description of a sound (one shot, looping, music, streamed, with added reverb...)
* Introduce Emitters: where the sound is played and what positional effects to add.
* Broken
 * There is a small "tick" at the end of the sample in the menu not sure why
 * Removed music for now
 * Removed looping sounds for now
