 ### Option: `noise_suppression`
 
-Enable noise suppression using speexdsp. This should be used for low quality
-microphones, or in noisy environments where noise suppression is not available
-on the voice satellite.
+Noise suppression level with
+[webrtc](https://github.com/rhasspy/webrtc-noise-gain), where 0 is disabled
+(default) and 4 is the max. Suppresses common sources of noise, such as fans,
+but may distort audio. This should be used for low quality microphones, or in
+noisy environments where noise suppression is not available on the voice
+satellite.
+
+### Option: `auto_gain`
+
+Automatic gain control target dBFS with
+[webrtc](https://github.com/rhasspy/webrtc-noise-gain), where 0 is disabled
+(default) and 31 is the max. Raises the volume when someone is speaking too
+quietly, but may distort audio. This should be used for low quality microphones,
+or if the voice satellite is far away and does not have auto-gain functionality.
+
+### Option: `save_audio`
+
+Enable recording of audio to `/share/openwakeword` as WAV files.
+**WARNING**: All audio is saved, including before the wake word is spoken, so this option should be disabled to preserve disk space.
 
 ### Option: `debug_logging`
 
-Enable debug logging. Useful for seeing each wake word detection in the logs.
+Enable debug logging. Useful for seeing satellite connections and each wake word detection in the logs.
