ORBAN Loudness Meter ~ Loudness & Peak Display


This software simultaneously displays instantaneous peaks, VU, PPM, CBS Technology Center loudness, and ITU BS.1770 loudness. All meters include peak-hold functionality that makes the peak indications of the meters easy to see.

The software accepts two-channel stereo inputs. The VU and PPM meters are split to indicate the left and right channels. The PPM meter also displays the instantaneous peak values of the L and R digital samples. ~ Hydrogen Audio
