Description Returns whether or not this AudioInput is monitoring. In other words, whether you will hear in your speakers the audio coming into the input.Signature boolean isMonitoring() Returns boolean: true if monitoring is on Related enableMonitoring ( )disableMonitoring ( ) AudioInput Example /**
* This sketch demonstrates how to monitor the currently active audio input
* of the computer using an AudioInput. What you will actually
* be monitoring depends on the current settings of the machine the sketch is running on.
* Typically, you will be monitoring the built-in microphone, but if running on a desktop
* it's feasible that the user may have the actual audio output of the computer
* as the active audio input, or something else entirely.
* <p>
* Press 'm' to toggle monitoring on and off.
* <p>
* When you run your sketch as an applet you will need to sign it in order to get an input.
