This README describes the audio assets, and how they relate to each other.
The product .mk references one of the AudioPackage*.mk,
which installs the appropriate assets into the destination directory.
For UI sound effects,
frameworks/base/media/java/android/media/AudioService.java array
SOUND_EFFECT_FILES contains a hard-coded list of asset filenames, stored
in directory SOUND_EFFECTS_PATH.
