 Smart Denoising has a simple on/off configuration:
 
-<ParamField path="smartDenoisingPlan.enabled" type="boolean" default="false">
+<ParamField path="smartDenoisingPlan.enabled" type="boolean" default="true">
   Enable or disable Krisp-powered smart denoising
 </ParamField>
 
+<Note>
+Smart Denoising is **on by default**. If you omit `backgroundSpeechDenoisingPlan`, Krisp still runs on your calls. To turn it off, set `smartDenoisingPlan.enabled` to `false`:
+
+```json
+{
+  "backgroundSpeechDenoisingPlan": {
+    "smartDenoisingPlan": {
+      "enabled": false
+    }
+  }
+}
+```
+</Note>
