1 Charles Babbage 26 December 1791 (London, UK) – 18 October 1871 (London, UK) Life and Times Charles Babbage was born into a wealthy family, and started his mathematics education very early. By . 1811, when he went to Trinity College, Cambridge, he found that he knew more mathematics then his professors. He moved to Peterhouse, Cambridge from where he graduated in 1814. However, rather than come second to his friend Herschel in the final examinations, Babbage decided not to compete for an honors degree. In 1815 he co-founded the Analytical Society dedicated to studying continental reforms of Newton's formulation of “The Calculus”. He was one of the founders of the Astronomical Society in 1820. In 1821 Babbage started work on his Difference Engine designed to accurately compile tables. Babbage received government funding to construct an actual machine, but they stopped the funding in 1832 when it became clear that its construction was running well over-budget George Schuetz completed a machine based on the design of the Difference Engine in 1854. On completing the design of the Difference Engine, Babbage started work on the Analytical Engine capable of more general symbolic manipulations. The design of the Analytical Engine was complete in 1856, but a complete machine would not be constructed for over a century. Babbage's interests were wide. It is claimed that he invented cow-catchers for railway engines, the uniform postal rate, a means of recognizing lighthouses. He was also interested in locks and ciphers. He was politically active and wrote many treatises. One of the more famous proposed the banning of street musicians. -

4. MPEG Layer-3 Audio Encoding
MPEG Layer-3 An introduction to MPEG Layer-3 K. Brandenburg and H. Popp Fraunhofer Institut für Integrierte Schaltungen (IIS) MPEG Layer-3, otherwise known as MP3, has generated a phenomenal interest among Internet users, or at least among those who want to download highly-compressed digital audio files at near-CD quality. This article provides an introduction to the work of the MPEG group which was, and still is, responsible for bringing this open (i.e. non-proprietary) compression standard to the forefront of Internet audio downloads. 1. Introduction The audio coding scheme MPEG Layer-3 will soon celebrate its 10th birthday, having been standardized in 1991. In its first years, the scheme was mainly used within DSP- based codecs for studio applications, allowing professionals to use ISDN phone lines as cost-effective music links with high sound quality. In 1995, MPEG Layer-3 was selected as the audio format for the digital satellite broadcasting system developed by World- Space. This was its first step into the mass market. Its second step soon followed, due to the use of the Internet for the electronic distribution of music. Here, the proliferation of audio material – coded with MPEG Layer-3 (aka MP3) – has shown an exponential growth since 1995. By early 1999, “.mp3” had become the most popular search term on the Web (according to http://www.searchterms.com). In 1998, the “MPMAN” (by Saehan Information Systems, South Korea) was the first portable MP3 player, pioneering the road for numerous other manufacturers of consumer electronics. “MP3” has been featured in many articles, mostly on the business pages of newspapers and periodicals, due to its enormous impact on the recording industry. -

In the beginning this was always done through human interpretations, such as telling stories and creating sculptures. Later, technological progress made it possible to create a recording of a phenomenon; first as an analogue recording onto a physical object, and later digitally, as a sequence of bits to be interpreted by a computer. -

Vajanske´ho 43, Nove`Za´mky, 94079, Slovakia Chair’s Introduction—7:55 Invited Papers 8:00 5aAAa1. Remarks on the definition of airborne sound insulation and consequences for uncertainties. Volker Wittstock (Physika- lisch-Technische Bundesanstalt, Bundesallee 100, Braunschweig 38118, Germany, [email protected]) Airborne sound insulation is explicitly defined as the ratio between incident and transmitted sound power. Since sound power cannot be measured directly, field quantities like sound pressure are measured to derive the desired sound power. The relation between sound pressure and sound power depends on the nature of the sound field, i.e., to which extent it is a diffuse sound field. This is the main reason why it is impossible to derive an analytic equation for the measurement uncertainty of a sound power and thus of a sound insulation. The current practice is to define standardized test facilities for the measurement of airborne sound insulation. The uncertainty of meas- ured sound insulations is then approximated by the standard deviation of reproducibility determined by interlaboratory tests. This is equivalent to changing the definition of airborne sound insulation. It is no longer the sound power ratio but the mean value of the sound insulation measured in very many or all thinkable laboratories meeting the required specifications. -

HEVC reAches formAl ISO/IEC committee drAft stAtus ISO/IEC’s Moving Picture Experts Group (MPEG) is pleased to announce the completion of the ISO/IEC committee draft of the High Efficiency Video Coding (HEVC) standard developed by the Joint Collaborative Team on Video Coding (JCT-VC), a joint team between MPEG and the ITU-T’s Video Coding Experts Group (VCEG). The committee draft was approved for balloting at the 99th MPEG meeting and is the first formal ISO/IEC milestone in the HEVC project. HEVC is expected to be submitted for final standardization approval in January 2013, and will be delivered as Part 2 of a new suite of standards known as MPEG-H (ISO/IEC 23008). The design of HEVC, the next generation of video compression standards, incorporates the latest state-of- the-art technologies and algorithmic advances to address the persistent demand for broader usage of video content, video migration to broadband networks, diversification of mobile devices, ever-higher resolutions for cameras and displays, and increasingly high video quality. -

FRAUNHOFER INSTITUTE FOR INTEGRATED CIRCUITS IIS PRESS RELEASE PRESS RELEASE October 13, 2015 || Page 1 | 3 mp3 developers to receive esteemed Eduard Rhein Award Erlangen/Munich, October 13, 2015: The Eduard Rhein Foundation has selected Prof. Dr.-Ing. Dr. h.c. Karlheinz Brandenburg, Dr.-Ing. Bernhard Grill and Prof. Dr.-Ing. Jürgen Herre to receive the 2015 Technology Award of the Eduard Rhein Foundation for their significant contributions to the development and implementation of mp3. The audio coding standard forever changed the world of music with its ability to allow music lovers to save their entire music library on a device as small as a matchbox for the very first time. The Eduard Rhein Foundation will present the award at a festive ceremony to be held in the Hall of Fame at the Deutsche Museum in Munich, Germany, on October 17. The 2015 Technology Award will be handed over to Karlheinz Brandenburg, Bernhard Grill and Jürgen Herre, three members of the mp3 team, to honor their “decisive contributions to the development and practical implementation of the mp3 audio coding technique.” Previous recipients of the foundation’s basic research awards include Shannon and Viterbi, absolute giants in their field of research. Naturally, being awarded ourselves is a great honor to us,” explains Jürgen Herre, chair holder for Perceptual Audio Coding at Friedrich-Alexander University Erlangen-Nürnberg (FAU). Dr. Bernhard Grill, head of the Audio & Multimedia division at the Fraunhofer Institute for Integrated Circuits IIS, adds: ”mp3 is the result of a big team’s hard work and persistency to find a way to reduce the size of audio files without risking loss of quality.
