Post Production And Broadcast: Audio Loudness Correction On Your File Based Content
Go beyond audio checks by automatically correcting audio loudness in the audio essence(s). Working with a variety of container types, audio level correction can be applied to the entire essence duration, and can be triggered by non-compliance to EBU R128 or ITU-1770-3 Audio Loudness Recommendations. Automated loudness correction works for Dolby Digital, Dolby Digital Plus, Dolby-E, PCM audio formats.
Broadcast: Learning To Live With Audio Loudness Standards
New changes to the ITU-R BS.1770-3 standard for measuring and controlling Audio Loudness now allow operators and engineers to easily monitor the audio loudness of their programs. Learn more about these important changes through this Tektronix webinar.
Part 1 provides information on the basics of the standards.
- Managing audio loudness using the updated ITU-R BS.1770-3 standards
- ATSC recommended practice A/85 that provide techniques for establishing and maintaining audio loudness (CALM Act)
Part 2 describes how to use a Tektronix Waveform Monitor or Rasterizer to measure and monitor audio loudness.
Cable Monitoring: The Storm Before the CALM: Quieting Loud Commercials On Cable
Cable operators have a tough job ahead: they must monitor the audio volume of commercials on many channels, not just one, and confirm that they have taken steps to control excessive loudness. This is a daunting task but help is on the way: the Sentry Video Content Monitor automates the process, 24/7, and keeps its own records. Download this Application Note to find out more.
Broadcast: Monitor Audio Loudness With Confidence, Day And Night
CALM Act compliance requirements never sleep, and neither can your audio loudness monitoring system. Sentry Edge’s versatile features make it possible to visualize 60-day summaries of audio loudness statistics and define custom alerts and technician contacts. And alert flooding is a thing of the past with Sentry Edge. Want to learn more?
Broadcast: Put Your Waveform Monitors And Rasterizers To Work On Loudness Compliance
Audio loudness is easy to perceive but can be difficult to control. A good first step is to make Audio Loudness compliance measurements with a capable waveform monitor and rasterizer. Our new how-to guide explains the techniques you’ll need when using Tektronix monitors to make measurements that conform to ITU-R BS.1770-3 and other applicable standards.
Cable Troubleshooting: QoS And QoE Troubleshooting And Diagnostics With The VQS1000 Video And Audio Quality Analysis Software.
The powerful VQS1000 software lets you analyze Audio Loudness Compliance in real time, and on a captured stream. Used together with the MTS4000 MPEG Analyzer, this software can relate QoE issues to the QoS source. See a quick overview of this powerful MPEG Analyzer using the VQS1000 Video and Audio Quality Analysis software.
