Tektronix’s Audio Test solutions can ensure audio loudness monitoring and compliance from Post Production, through to Broadcasters and Cable Operators. Our consistent Audio test and measurement approach makes Audio Loudness measurements the same way, regardless of signal or file format. This consistency enables traceability across the workflow and transmission chain.
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)
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.

|Audio Loudness Monitoring How-To Guide|
This hands-on guide making Audio Loudness measurements with the Tektronix waveform monitors or rasterizers provides step by step instructions on how to configure a waveform monitor to make loudness measurements to one of the standards ATSC A/85, EBU R 128 or ARIB TR-B.32.
|Measuring Video and Audio Quality of Experience (QoE)|
This application note shows you how to objectively rate a program at different points in the network to understand and pinpoint when and where degradation has occurred.
Audio devices use either balanced or unbalanced signals. Each format has its own physical and electrical characteristics and specific strengths and weaknesses. A good understanding of these formats will aid in the understanding and appropriate application of audio signals.
