 ### How It Works
 Voice effects are applied to your outgoing audio in real-time, after noise suppression and automatic gain control. The effects use various digital signal processing techniques including delay lines, pitch shifting with cubic interpolation, and ring modulation.

 ### Configuration Example
-```yaml
+```toml
-noisesuppressionenabled: true
+noisesuppressionenabled = true
-noisesuppressionthreshold: 0.02
+noisesuppressionthreshold = 0.02
 ```
 
 The noise suppression algorithm uses a combination of high-pass filtering and noise gating to reduce unwanted background sounds while preserving voice quality.
