+### Start a call with Noise Suppression enabled
+To start a call with **noise suppression** turned on, you can create a new `LocalAudioStream` with a `AudioDeviceInfo` (the LocalAudioStream source <u>shouldn't</u> be a raw `MediaStream` to use audio effects), and pass it in the `CallStartOptions.audioOptions`:

 ### How to turn on Noise Suppression during an ongoing call
 There are situations where a user might start a call and not have **noise suppression** turned on, but their current environment might get noisy resulting in them needing to turn on **noise suppression**. To turn on **noise suppression**, you can use the `audioEffectsFeatureApi.startEffects` API.
