  • A History of Audio Effects
    applied sciences Review A History of Audio Effects Thomas Wilmering 1,∗ , David Moffat 2 , Alessia Milo 1 and Mark B. Sandler 1 1 Centre for Digital Music, Queen Mary University of London, London E1 4NS, UK; [email protected] (A.M.); [email protected] (M.B.S.) 2 Interdisciplinary Centre for Computer Music Research, University of Plymouth, Plymouth PL4 8AA, UK; [email protected] * Correspondence: [email protected] Received: 16 December 2019; Accepted: 13 January 2020; Published: 22 January 2020 Abstract: Audio effects are an essential tool that the field of music production relies upon. The ability to intentionally manipulate and modify a piece of sound has opened up considerable opportunities for music making. The evolution of technology has often driven new audio tools and effects, from early architectural acoustics through electromechanical and electronic devices to the digitisation of music production studios. Throughout time, music has constantly borrowed ideas and technological advancements from all other fields and contributed back to the innovative technology. This is defined as transsectorial innovation and fundamentally underpins the technological developments of audio effects. The development and evolution of audio effect technology is discussed, highlighting major technical breakthroughs and the impact of available audio effects. Keywords: audio effects; history; transsectorial innovation; technology; audio processing; music production 1. Introduction In this article, we describe the history of audio effects with regards to musical composition (music performance and production). We define audio effects as the controlled transformation of a sound typically based on some control parameters. As such, the term sound transformation can be considered synonymous with audio effect.

  • Telephone – Inventions That Revolutionized the World
    Telephone – Inventions that Revolutionized the World December 14, 2018 First Publication Date: 27th November 2010 The most common devices used for transmitting the voice signal over a greater distance are pipes and other physical mechanical media. All of us as a child must have used this form for communication. Another device used for centuries for voice communication is lover’s phone or tin can telephone. The classic example is the children’s toy made by connecting the bottoms of two paper cups, metal cans, or plastic bottles with string. But the invention which changed the entire scenario of the communication is the telephone. It revolutionized the entire communication system. People could hear the voice of their loved ones staying miles away. Telephone comes from the Greek word tele, meaning from afar, and phone, meaning voice or voiced sound. Generally, a telephone is any device which conveys sound over a distance During the second half of the 19th century many well-known inventors were trying to develop an acoustic telegraphy for economic telegraph messages which included Charles Bourseul, Thomas Edison, Antonio Meucci, Johann Philipp Reis, Elisha Gray, and Alexander Graham Bell. The ‘speaking telegraph’ or in simple terms ‘telephone’ emerged from the creation and gradual improvement of telegraph. The invention of telephone has been one of the most disputed facts of all time. Credit for the invention of the electric telephone is never an ending dispute and new controversies over the issue keeps arising from time-to-time. The Elisha Gray and Alexander Bell controversy raises the question of whether Bell and Gray invented the telephone independently and, if that’s not true, then whether Bell stole the invention from Gray.

Networking, routers, routing protocols, and networking over the public Internet have their specifications defined in documents called RFCs. Computer networking is sometimes considered a sub-discipline of telecommunications, computer science, information technology and/or computer engineering. Computer networks rely heavily upon theWWW.BSSVE.IN theoretical and practical application of these scientific and engineering disciplines. All networks are interconnected to allow communication with a variety of different kinds of media, including twisted-pair copper wire cable, coaxial cable, optical fiber, and various wireless technologies. The devices can be separated by a few meters (e.g. via Bluetooth) or nearly unlimited distances (e.g. via the interconnections of the Internet). Key Points: 1.

  • On Development of Information Communications in Human Society
    Interdisciplinary Description of Complex Systems 17(3-B), 520-545, 2019 ON DEVELOPMENT OF INFORMATION COMMUNICATIONS IN HUMAN SOCIETY Bangwei Zhang* Hunan University, College of Physics Changsha, People’s Republic of China DOI: 10.7906/indecs.17.3.13 Received: 21 May 2019. Regular article Accepted: 27 September 2019. ABSTRACT Information is very important. Information is also very complicated, making that people have no common understanding and conclusion for the nature of it up today. There are too many papers and some books to describe information; however it is rather difficult to find the description and analysing for the whole history of information from the advent of human beings to the present day. Two parts of information in prehistoric period and the time interred divinization are described. Every part is separated according to several succeeded stages for description. It is near impossible to describe in detail such entire historical facts of information in human society in a paper, so the description and discussion is focused on their comprehensiveness and integrity. By knowing and analysing all these solid historical facts of information, some relative issues e.g. “did information age really exist in the development of material civilization in human society” can be recognized easily. KEY WORDS information, history of information, information communication, matter, substance civilization, six-stage theory CLASSIFICATION JEL: B10, D83 *Corresponding author, : [email protected]; +0731 88822715; *College of Physics, Hunan University, Changsha 410 082, People’s Republic of China * On development of information communications in human society INTRODUCTION Near everybody knows the importance of information because nobody can leave the information and it communications.

  • Director's Report
    Published by the Telecommunications History Group, Inc. DENVER, COLORADO (303) 296-1221 www.telcomhistory.org Autumn 2012, Vol. 16, no. 3 Jody Georgeson, editor Director’s Report by Jody Georgeson I thought you might like to know a little more about archives and museums and why we think it is important to preserve the history of our industry. History is important to all of us because it is the heritage that shaped the world we live in today. It helps us to understand the world, and how it became what we see today. It can help us to solve problems that we face today by seeing solutions that were tried, successfully or not, in the past. Authoritative historical work will always rely on oral tradition, personal memoirs, and other semi-official works, but it is doubtful that new history will be written without the cumulative and verifiable sources found in museums and in archival depositories. Besides the historical importance, an important reason for the existence of archives and museums is a cultural one. Our collections are as important a cultural resource as paintings and sculptures, monuments, landscapes, archaeological sites, buildings, and religious beliefs and practices. The mission of any historical institution is to identify artifacts and documents of enduring value; to preserve them; and to make them available to patrons. THG’s focus is to help our communities understand how telecommunications has shaped our lives and our world. In order to accomplish our mission, we rely on our wonderful volunteers and on our members. How can you help? Donate materials - Most of us have things in our home which we’ve saved as reminders of our careers in the telecom industry.
