Before After File-based audio loudness and normalisation Faster than real-time Professional broadcast workflows are changing from conventional baseband signals to a wide range of file-based containers and codecs. This drive to efficient file-based operations means that it is now important to use tools which have been specifically designed to capitalise on filebased workflows.. Loudness and audio normalisation is a task which, when addressed using conventional means, is long and laborious; conversion of file to baseband signal, adjustment of levels in real-time with subsequent conversion back to a file. Emotion Broadcast Systems have addressed this real-world problem with eff, the first of a line of applications based on the powerful and flexible Emotion Systems Platform. eff opens up wrappers, codecs and files including MXF, DPP, AVC-I, analyses the audio in them, adjusts levels and ensures compliance with a wide range of selectable standards at speeds faster than real-time. What s more, this process can even be automated for maximum efficiency. Signal Processing Solutions for File Based Workflows
eff is the loudness and audio normalisation tool designed by Emotion Systems to solve the challenge of compliance and adjustment for file-based workflows. Delivering compliance standards, it offers maximum efficiency and faster than real-time operation with the ability to be integrated into a to a wide range of selectable, recognised wide range of different workflows. Analyse thorough analysis of the full file to ensure that any adjustments that are made, maintain the integrity of the content. eff works through three clear stages as it works on files. Correction adjustments are made to the audio levels within the file, based on the overall analysis which means that content integrity is fully maintained. Report reports are created which allows users to see which files have passed, which files have failed and the alterations required. Operational Speed eff will not only ensure that your content is loudness compliant but it will also deliver this at faster than real-time. This means that it can be integrated into your workflow with minimun impact to productivity and maximum impact to efficiency. Benefits - Compliance to a wide range of selectable standards - Processing all done within the file domain for faster than real-time results - Automated process for efficient operations - Integration into a wide range of different work flows - Supports mono, multiple mono, multi-lingual stereo, stereo, multi-channel, Dolby E. Different Tracks Whether your requirement is numerous mono tracks with different languages, several stereo tracks or 5.1, rest-assured that eff has been designed with your needs in mind.
Compliance Standards Numerous standards exist, each with their own nuance and levels requirements. eff is currently available with support of a wide range of standards with more to be added in the future with ongoing software support. Workflows eff has been designed to work in a number of different ways, depending on your requirements. Manually drop a file into eff and manually control its functions. Automatic select a group of files to be made compliant and drop them into a watch folder to let eff automatically analyse, report and measure each one in turn. Integrated integrate eff into your MAM workflow to ensure loudness compliance in all that you do. Options True Peak True Peak audio normalisation using the Dynamic Normalisation Algorithm (DNA) is now available as an option within eff. This allows the system to identify and correct true signal peaks. API Emotion Systems are proud to announce that Dolby E is now supported within eff. This means that eff now has ability to open Dolby E encoded content to ensure that it is loudness compliant. eff has been carefully developed using the Emotions Systems Platform and is available with its own comprehensive API. This means that it can be fully integrated into a comprehensive workflow using the API. Dialogue Intelligence eff now offers Dialogue Intelligence speech-gating technology to focus analysis of content on the areas of a program which contain dialogue.

True Peak DNA Loudness measurement and compliance does not necessarily address True Peak violations. True Peaks are signal peaks which are very short. Because they are very short, they do not affect the loudness measurement but, if not eliminated, would result in clipping. eff True Peak DNA, has been specially designed to inaudibly reduce these peaks to the True Peak threshold set, using high quality engineering principles.

API Operation eff enterprise has a comprehensive API (application programming interface) for control within a fully automated environment. API commands include: - select file and loudness compliance standard for processing - check on file progress through loudness compliance - reporting on the status of file sent for processing Watchfolder Operation eff enterprise has the ability to use a watchfolder. Drop files for loudness processing into the watchfolder and files, once processed by eff will appear in the output folder. Folders available in eff watchfolder mode include; Watch Folder (for input files), Corrected Folder (for output files), Error folder (for files which showed an error during analysis or correction) and a group of folders for different reports. Customisation Emotion Systems are also able to undertake customisation and integration work for clients who would like to integrate eff into their own specialised workflow.
