Emotion delivers file-based automated loudness control at NAB 2013 05 Apr 2013

File-based signal processing specialist Emotion Systems will use NAB 2013 to launch version 3.0 of eFF, its revolutionary automated loudness analysis and compliance software. The new version provides fast processing of all common file formats including Panasonic P2, and runs on OS X, Windows and Linux. The same processing platform also supports new video pre-processing tool eVe, shown for the first time at NAB 2013.

Loudness is a critical issue for broadcasters worldwide. With the CALM Act in the USA and a growing regulatory requirement in the rest of the world based on the requirements of ITU recommendations 1770 and 1771, eFF is a simple software application that takes a radical approach to loudness processing.

First, it handles the content in the file domain with no time or quality loss in decoding to baseband and the ability to handle any type of file including Dolby E audio, and MXF Op Atom, which can include multiple video segment files in a single wrapper. Second, it measures in one pass all the parameters: momentary loudness, short-term loudness, long-term loudness and true peak levels. Third, it can either deliver a detailed report on conformation, or it can automatically adjust still in the file domain levels to achieve compliance.

File-based loudness processing has now become an urgent issue for broadcasters, said MC Patel, founder and CEO of Emotion Systems. It has to sit inside an automated workflow, be completely predictable and reliable in performance, serve all file types transparently, and above all be fast and have no impact on the file except for correcting audio levels where needed.

eFF is already in use with major broadcasters and production companies around the world, including Sony Pictures, NBC Access Hollywood, post house The Mill in New York and Los Angeles, Encompass Media, Ericsson, France 1 and Japanese national broadcaster NHK. Some of the added functionality in version 3.0 was prompted by NHK, which needed an automated tool to batch process tens of thousands of hours of P2 format video in an archiving project.

The new release also includes support for Dolby E, and we have extended our dynamic normalisation algorithm (DNA) to cover true peak correction - more functionality added at the request of our users, Patel added. We are proud to be chosen by major broadcasters as providers of loudness solutions for their real-world challenges.

NAB 2013 also sees the launch of eVe, the Emotion Video Engine, a file-based media toolbox which includes a media analyser, a player and an XML export tool. It provides pre-processing and preparation of file-based media for multi-platform authoring, among other applications.

Emotion Systems can be found at NAB 2013 on booth SU8603.
