SoundThemeChanger is an application which allows you to change Sound Sets used in MacOS 8.5. Besides the ability to change Sound Sets you can also record your own sounds for use in the soundset (max 10 sec.). The registered version even lets you extract sounds from files, if these sounds are stored in the snd resource. For example it is possible to extract sounds from different sound sets and to create your own sound set with it.
Because it is very hard to get all sound resources documented, SoundThemeChangers has a section with undefined resources, these are sounds in the theme file which don't have a name or category assigned yet. However SoundThemeChanger has the unique capability to add sound resources, all you have to do is give a unique resource number (the resource number has to be used by the system otherwise it will never be played) name and assign it to a category.
