+# Sound API
+
+
+## Option 1: Agnostically depend
+
+You can do this by using a custom field in your node def instead of the `sounds` key.
+
+```lua
+minetest.register_node(nodename, {
+    ...
+    _sound_def = {
+        key = "",
+        input = {},
+    },
+    ...
+})
+```
+
+where:
+
+* key: string name of the field from the sound api you want to use, for example `node_sound_stone_defaults`
+* input: table input of fields you want passed to the key field, used to override specific sounds.
+
+## Option 2: Hard depend
+
+add this mod to your mod.confs depends and directly call the `sound_api` as follows
+
+```lua
+minetest.register_node(nodename, {
+    ...
+    sounds = xcompat.sounds.node_sound_stone_defaults(input)
+    ...
+})
+```
+
+* input: optional table to override some or all of returned values
+
+
+## Note
+
+In some instances, when sounds are defined by strings and the sound doesn't
+belong to a block or anything mod-specific, xcompat may not be needed. E.g.
+the sound `"default_dig_choppy"` is accessed in the same way in both Mineclonia
+and Minetest Game, without xcompat.
