All Implemented Interfaces:

DataProcessor, Configurable

public class VUMeterMonitor
extends BaseDataProcessor

A VU meter to be plugged into a front-end. Preferably this component should be plugged directly behind the DataBlocker in order to ensure that only equally sized blocks of meaningful length are used for RMS computation.

Because vu-monitoring makes sense only for online speech processing the vu-meter will be visible only if data source which precedes it is a Microphone.
