CALM-compliant performances at PBS
Keeping performances CALM-Compliant for PBS using VisLM
by David Hough, Audio Director of Austin City Lmits
The history graph in the VisLM visual loudness meter clearly shows me the boundaries for both dialog and music. I use the histogram to help adjust the dynamic range to meet PBS specs. VisLM saves so much time because I have a history that shows me an entire song. I can ensure an entire musical performance is compliant using about five minutes of visual history (about the length of one song).
Having a show returned for being out of spec costs valuable time and money, so I count on NUGEN Audio’s VisLM visual loudness meter and LM-Correct loudness analysis and correction tool to ensure we’re CALM-compliant. Since I started using VisLM and LM-Correct, PBS has not rejected or returned any of the programs I’ve delivered.
NUGEN Audio tools give me a fast and easy way to measure loudness. Compared to other meters I’ve used, NUGEN Audio meters have dramatically improved the accuracy of the loudness reading in a much shorter time – which is especially valuable when I’m at the end of the process and approaching a deadline!
I use NUGEN’s LM-Correct tool to ensure distinct containers within my mix meet PBS’s strict loudness standards. I simply select a specific container from the master mix, and LM-Correct measures and adjusts it in seconds. Finally I have a tool that helps me comply within 0.1 dB!
