 ## Checking the audio stream volume
-As a developer it can be nice to have the ability to check and display to end users the current local microphone volume or the incoming microphone level. Azure Communication Services calling API exposes this information using `getVolume`. The `getVolume` value is a number ranging from 0 to 100 (with 0 noting zero audio detected, 100 as the max level detectable). This value is sampled every 200 ms to get near real time value of volume level.

This value is sampled every 200 ms to get near real time value of volume level. Different microphone hardware has different level of sensitivity and it can show different volume levels for the similar environment.
 
 ### Example usage
 This example shows how to generate the volume level by accessing `getVolume` of the local audio stream and of the remote incoming audio stream.
