 ### Gain
 
-When you change gain, LVA(using the webrtc library) automatically adjusts the microphone input volume to keep it at a consistent level. If you're speaking quietly it boosts the signal, if you're speaking loudly it reduces it. Useful in the following ways:-

 ### Noise Suppression
 
-When you change noise suppression, LVA(using the webrtc library) filters out constant background noise from the audio signal. It works by learning what "silence" sounds like in your environment and subtracting that from the audio. Useful in the following ways:

 - If the wake word **rarely activates** (misses your voice): lower the value slightly, e.g. by `0.05` steps
 - If the wake word **activates too often** (false triggers from TV, music, or similar words): raise the value slightly
 - Start from the model's default and make small adjustments — a change of `0.05–0.10` is usually enough to notice a difference
