Echo (music Award) Winners
In audio signal processing and acoustics, an echo is a reflection of sound that arrives at the listener with a delay after the direct sound. The delay is directly proportional to the distance of the reflecting surface from the source and the listener. Typical examples are the echo produced by the bottom of a well, by a building, or by the walls of an enclosed room and an empty room. A true echo is a single reflection of the sound source. The word ''echo'' derives from the Greek ἠχώ (''ēchō''), itself from ἦχος (''ēchos''), "sound". Echo in the Greek folk story is a mountain nymph whose ability to speak was cursed, leaving her able only to repeat the last words spoken to her. Some animals use echo for location sensing and navigation, such as cetaceans (dolphins and whales) and bats in a process known as echolocation. Echoes are also the basis of Sonar technology. Acoustic phenomenon Acoustic waves are reflected by walls or other hard surfaces, such as mountains and pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Audio Signal Processing
Audio signal processing is a subfield of signal processing that is concerned with the electronic manipulation of audio signals. Audio signals are electronic representations of sound waves—longitudinal waves which travel through air, consisting of compressions and rarefactions. The energy contained in audio signals is typically measured in decibels. As audio signals may be represented in either digital or analog format, processing may occur in either domain. Analog processors operate directly on the electrical signal, while digital processors operate mathematically on its digital representation. History The motivation for audio signal processing began at the beginning of the 20th century with inventions like the telephone, phonograph, and radio that allowed for the transmission and storage of audio signals. Audio processing was necessary for early radio broadcasting, as there were many problems with studio-to-transmitter links. The theory of signal processing and its appli ...

Magnetic Tape
Magnetic tape is a medium for magnetic storage made of a thin, magnetizable coating on a long, narrow strip of plastic film. It was developed in Germany in 1928, based on the earlier magnetic wire recording from Denmark. Devices that use magnetic tape could with relative ease record and playback audio, visual, and binary computer data. Magnetic tape revolutionized sound recording and reproduction and broadcasting. It allowed radio, which had always been broadcast live, to be recorded for later or repeated airing. Since the early 1950s, magnetic tape has been used with computers to store large quantities of data and is still used for backup purposes. Magnetic tape begins to degrade after 10–20 years and therefore is not an ideal medium for long-term archival storage. Durability While good for short-term use, magnetic tape is highly prone to disintegration. Depending on the environment, this process may begin after 10–20 years. Over time, magnetic tape made in the 197 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bijapur, Karnataka
Bijapur, officially known as Vijayapura, is the district headquarters of Bijapur district of the Karnataka state of India. It is also the headquarters for Bijapur Taluk. Bijapur city is well known for its historical monuments of architectural importance built during the rule of the Adil Shahi dynasty. It is also well known for the sports by the popular Karnataka premier league team as Bijapur Bulls. Bijapur is located northwest of the state capital Bangalore and about from Mumbai and west of the city of Hyderabad. The city was established in the 10th–11th centuries by the Kalyani Chalukyas and was known as ''Vijayapura'' (city of victory). The city was passed to Yadavas after Chalukya's demise. In 1347, the area was conquered by the Bahmani Sultanate. After the split of the Bahmani Sultanate, the Bijapur Sultanate ruled from the city. Relics of the Sultanates' rule can be found in the city, including the Bijapur Fort, Bara Kaman, Jama Masjid, and Gol Gumbaz. Bijapur, one ...

Gol Gumbaz
Gol Gumbaz (), also written Gol Gumbad, is a 17th-century mausoleum located in Bijapur, a city in Karnataka, India. It houses the remains of Mohammad Adil Shah, seventh sultan of the Adil Shahi dynasty, and some of his relatives. Begun in the mid-17th century, the structure never reached completion. The mausoleum is notable for its scale and exceptionally large dome. It is an important example of the southern regional style of Indo-Islamic architecture. The building is one of those put by UNESCO on its "tentative list" to become a World Heritage Site in 2014, under the name Monuments and Forts of the Deccan Sultanate. History The construction of the Gol Gumbaz began in the mid-17th century, during the close of Mohammad Adil Shah's reign, which was from 1627 to 1656. It is located directly behind the ''dargah'' of Hashim Pir, a Sufi saint; Richard Eaton views this as suggestive of the close relationship between the ruler and the saint. The mausoleum was never completed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scotland
Scotland (, ) is a country that is part of the United Kingdom. Covering the northern third of the island of Great Britain, mainland Scotland has a border with England to the southeast and is otherwise surrounded by the Atlantic Ocean to the north and west, the North Sea to the northeast and east, and the Irish Sea to the south. It also contains more than 790 islands, principally in the archipelagos of the Hebrides and the Northern Isles. Most of the population, including the capital Edinburgh, is concentrated in the Central Belt—the plain between the Scottish Highlands and the Southern Uplands—in the Scottish Lowlands. Scotland is divided into 32 administrative subdivisions or local authorities, known as council areas. Glasgow City is the largest council area in terms of population, with Highland being the largest in terms of area. Limited self-governing power, covering matters such as education, social services and roads and transportation, is devolved from the Scott ...

Lanarkshire
Lanarkshire, also called the County of Lanark ( gd, Siorrachd Lannraig; sco, Lanrikshire), is a historic county, lieutenancy area and registration county in the central Lowlands of Scotland. Lanarkshire is the most populous county in Scotland, as it contains most of Glasgow and the surrounding conurbation. In earlier times it had considerably greater boundaries, including neighbouring Renfrewshire until 1402. Lanarkshire is bounded to the north by the counties of Stirlingshire and Dunbartonshire (this boundary is split into two sections owing to Dunbartonshire's Cumbernauld exclave), to the northeast by West Lothian and Mid Lothian, to the east by Peeblesshire, to the south by Dumfriesshire, and to the west by Ayrshire and Renfrewshire. Administrative history Lanarkshire was historically divided between two administrative areas. In the mid-18th century it was divided again into three wards: the upper, middle and lower wards with their administrative centres at Lanark, Hamil ...

Inchindown Oil Tanks
The Inchindown oil tanks is a disused underground oil depot in Invergordon, Ross-shire, Scotland. The tanks hold the record for the longest reverberation in any man-made structure, surpassing the Hamilton Mausoleum in 2014. History The secret site was officially called "Inchindown, Royal Navy Fuel Tanks" and also known as the "Invergordon Oil Fuel Depot". The complex consists of six tanks: five were long, wide, with arched roofs high; a smaller sixth tank was of the same height and breadth but shorter. Work on the tanks began in 1938 and was completed in 1941. They were built to be a bomb-proof supply of furnace fuel oil to the Royal Navy's base at Invergordon. In 2014, the tanks were designated as a Category A listed building. Reverberation record In 2009, guided tours of the tanks were offered by Forestry Commission Scotland.

Toothed Whale Sound Production
A tooth ( : teeth) is a hard, calcified structure found in the jaws (or mouths) of many vertebrates and used to break down food. Some animals, particularly carnivores and omnivores, also use teeth to help with capturing or wounding prey, tearing food, for defensive purposes, to intimidate other animals often including their own, or to carry prey or their young. The roots of teeth are covered by gums. Teeth are not made of bone, but rather of multiple tissues of varying density and hardness that originate from the embryonic germ layer, the ectoderm. The general structure of teeth is similar across the vertebrates, although there is considerable variation in their form and position. The teeth of mammals have deep roots, and this pattern is also found in some fish, and in crocodilians. In most teleost fish, however, the teeth are attached to the outer surface of the bone, while in lizards they are attached to the inner surface of the jaw by one side. In cartilaginous fish, such ...

Effects Unit
An effects unit or effects pedal is an electronic device that alters the sound of a musical instrument or other audio source through audio signal processing. Common effects include distortion/overdrive, often used with electric guitar in electric blues and rock music; dynamic effects such as volume pedals and compressors, which affect loudness; filters such as wah-wah pedals and graphic equalizers, which modify frequency ranges; modulation effects, such as chorus, flangers and phasers; pitch effects such as pitch shifters; and time effects, such as reverb and delay, which create echoing sounds and emulate the sound of different spaces. Most modern effects use solid-state electronics or digital signal processors. Some effects, particularly older ones such as Leslie speakers and spring reverbs, use mechanical components or vacuum tubes. Effects are often used as stompboxes, typically placed on the floor and controlled with footswitches. They may also be built into guita ...

Solid State (electronics)
Solid-state electronics means semiconductor electronics: electronic equipment using semiconductor devices such as transistors, diodes and integrated circuits (ICs). The term is also used as an adjective for devices in which semiconductor electronics that have no moving parts replace devices with moving parts, such as the solid-state relay in which transistor switches are used in place of a moving-arm electromechanical relay, or the solid-state drive (SSD) a type of semiconductor memory used in computers to replace hard disk drives, which store data on a rotating disk. History The term "solid-state" became popular at the beginning of the semiconductor era in the 1960s to distinguish this new technology based on the transistor, in which the electronic action of devices occurred in a solid state, from previous electronic equipment that used vacuum tubes, in which the electronic action occurred in a gaseous state. A semiconductor device works by controlling an electric current c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
