(New at IBC) Top questions: audio and file ­based workflows

We have had a busy summer with a number of large customer projects. This IBC, we’d like to show you some of the work and technology that has been influenced by customer needs. Here’s a little summary of what we’ve been hearing lately:

1. “I need a better way automate loudness correction given the need to use short term and momentary. Do you have something smarter that can automatically process exactly, and only, what’s required?”

2. “Can you help me deal with SD or HD files? 4 channels or 8? I want a system that will figure out what processes are needed and just do it. I don’t want an operator to determine what’s needed – I want the tool to do it for me.”

3. “We need help with all the language requirements that keep coming up. We need to package and tag content with different languages.”

If you prepare content for delivery and have more and more workflow requirements, these questions may resonate with you, too. Come see us at IBC. We’ve got new technology to share with you that will solve the above questions and more: a new loudness processor, new language tagging module, and a new conditional workflow module.


Short Term Loudness: EBU R128 and DPP EBU have basically said that for short form content, there may be a case for doing short term and momentary loudness. Our new processor allows you to do that. EFF and Engine software now include optional short­term and momentary loudness processors. The PPM and True Peak processors have been enhanced to give you optimal sonic quality with a every type of program material

Loudness Range (LRA) The new LRA in processor Eff and Engine applies carefully calculated compression so that LRA targets can be met in conjunction with any combination of the other loudness parameters

Need more channels?
Have too many channels?

Growing (or shrinking) channels manually is tedious, repetitive process. But when processing MXF or MOV files, it is often a requirement to change the number of audio channels in the file. Now you can let Engine do it for you. Sometimes playout systems work with a normalised file format that is typically 8 channels, yet source files are often delivered with just two channels. An alternative requirement is where 16 channel files have been used so as to contain two separate stereo and 5.1 tracks, but again it is necessary to deliver 8 channel files to subsequent playout. Engine has the capability to flexibly change the number of audio channels in standard media files to suit these applications.

Audio Description (AD) Engine can automatically create an Audio Description (AD) sound track from a combination of the main audio, a separately recorded commentary track, and a control track. You may need this if you are delivering content to mobile devices that do not contain hardware to generate the AD sound track in the manner employed in television set top boxes.
