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 short-term 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.
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.
I need more channels? I have too many channels?
When processing MXF or MOV files, it is often a requirement to change the number of audio channels in the file. But growing (or shrinking) channels manually is tedious, repetitive process. Now, Engine can 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.
