At this year’s NAB Show, the world’s largest convention for the digital media industry, taking place April 18 – 21 in Las Vegas, Fraunhofer IDMT for the first time will be presenting its “Audio Forensics Toolbox”. The software package allows users to detect traces of previous editing and encoding steps in audio material, in order to assess the quality of recordings and optimize workflows in production processes.
-- Assessing the quality of audio content --
There are many application contexts in which the quality of audio material is critical for its further use. Media archives or providers of audio and video files, for example, need to validate digital content quickly and easily in terms of whether the content has been edited or encoded at some point in time.
Such validation enables users to determine the quality of the material and optimize their own editing and encoding processes.
-- Easy creation and linking of metadata --
In the course of editing and encoding audio content, characteristic traces (i.e. metadata) are left in the material. The “Audio Forensics Toolbox” allows users to identify the devices and microphones used for a recording, detect cuts and splices in audio material, and find out whether certain segments have been reused in a new context.
This helps content aggregators and broadcasters avoid redundancies and inconsistencies in the material they use.
-- A/V inspector --
Alongside with the “Audio Forensics Toolbox”, Fraunhofer IDMT will be presenting an update of its “AV Analyzing Toolbox”, which can be used to optimize processes for broadcasting, distributing, and archiving digital content. This Toolbox comprises various components for automatic identification of flaws and quality deficiencies in digital audio and video content.
In addition, the Toolbox comes with a video segment matching component, which recognizes identical video segments across different videos (even if the content has been edited or transcoded) and determines their exact position and length.
Another component of the Toolbox allows automatic measurement of the exact amount of music in radio and TV programs, offering support in the context of accurate accounting and more efficient queries of programs.
The institute presents its tools for analyzing audio and video content at the Fraunhofer booth SU6716 in the South Upper Hall.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
