Linear Acoustics Keeping Calm

It’s common knowledge in the television industry today that the CALM Act has had a significant impact on broadcasters, as they now have to pay closer attention to their audio levels. However, compliance regulations have also reinforced the importance of correct audio levels to content creators and production houses as well.                       

Most post-production company have already increased their attention towards audio, making sure that the content created is not only engaging, but also loudness-compliant. That focus has not been without its challenges.

This is relatively new ground for most people and companies of the broadcast chain. For many years, emphasis has been primarily on video, not audio, but nowadays, it’s not uncommon to see some pretty inconsistent audio levels between different programs, and even within a single piece of content. This has been a pondering issue for the industries.

Audio engineers suggested investigating equipment from Linear Acoustic for a solution. After a lot of research and the evaluation of numerous products from several manufacturers, they have determined that Linear Acoustic’s AERO.100 DTV Audio Processor was the correct solution.

A much needed audio measurement and processing device with SDI I/O, a good user interface and the ability to produce compliant audio with an emphasis on audio quality. That’s where the AERO.100 really stands out. The processed audio from it is not only compliant, but also is top-notch in quality, providing compelling and clear audio for the viewers at home.

Among the more useful features of the AERO.100 in common application are the built-in ITU-R BS.1770 LFKS meters. Content runs though the unit without processing it, just to measure the levels. There are four separate meters, each with a user-selectable integration time, so they can look at short-term dynamics and the mid- and long-term averages at the same time. This lets the production crews identify exactly where the content is inconsistent or non-compliant, they can use AERO.100 processing to bring everything into compliance for their clients thus allowing them to facilitate their client’s needs with complete confidence.

Linear Acoustic has been the go-to manufacturer of processors and meters for television networks and local stations worldwide for more than a decade, but their products definitely have a place on the production side as well. The AERO.100 has proven to be an invaluable tool for them since then.
