getLevel

Read the Amplitude (volume level) of an AudioIn. The AudioIn class contains its own instance of the Amplitude class to help make it easy to get a microphone's volume level. Accepts an optional smoothing value (0.0 < 1.0). NOTE: AudioIn must .start() before using .getLevel().

Syntax


  
      getLevel([smoothing])

Parameters

smoothing

Number:

Smoothing is 0.0 by default. Smooths values based on previous values.

Returns

Number: Volume level (between 0.0 and 1.0)
