Orban says the first public beta of its Orban Loudness Meter Software for Windows XP and Vista is available for free download.
This is the first in a series of meters for the company. The beta version simultaneously displays instantaneous peaks, VU, PPM, CBS Technology Center loudness and ITU BS.1770 loudness. Meters include peak-hold functionality that makes the peak indications of the meters easy to see.
The CBS meter is a “short-term” loudness meter intended to display the details of moment-to-moment loudness with dynamics similar to a VU meter. It uses the Jones & Torick algorithm developed at the CBS Technology Center, published in 1981 in the SMPTE Journal, Orban said.
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.
Future paid versions of Orban Loudness Meter software will have features like logging, surround monitoring and oversampled peak measurements that indicate the peak level of the audio after D/A conversion.
