AudioInput disableMonitoring | Description When monitoring is disabled, you will not hear the audio that is coming through the input, but you will still be able to access the samples in the left, right, and mix buffers. This is default state of an AudioInput and is what you will want if your input is microphone and your output is speakers. Otherwise: feedback. Signature

Returns None Related enableMonitoring ( ) isMonitoring ( ) 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.
      * <p>
