Roxette
–
Roxette is a Swedish pop rock duo, consisting of Marie Fredriksson and Per Gessle. Formed in 1986, the duo became an act in the late 1980s. Their third album Joyride, which was released in 1991, became just as successful as its predecessor. Roxette went on to achieve nineteen UK Top 40 hits and several US Hot 100 hits, including four US number-ones with The Look, Listen to Your Heart, It Must Have Been Love, and Joyride. Other hits include Dangerous, Fading Like a Flower, Dressed for Success, on the advice of the managing director of their record label, they came together to record Neverending Love, which became a hit single in Sweden. After the release of Dont Bore Us, Get to the Chorus, a greatest hits record, the duo took a hiatus from the mid-1990s before returning with the albums Have a Nice Day and Room Service. They continued to chart in other territories, mainly in Europe and Latin America, in 2002, the duo took a break from recording and touring when Fredriksson was diagnosed with a brain tumour. In 2011, they released Charm School, their first studio album in ten years and this was followed by Travelling a year later. Their songs It Must Have Been Love and Listen to Your Heart continue to receive radio airplay. Per Gessle and Marie Fredriksson first met in Halmstad, Sweden, Gessle performed in Gyllene Tider, one of Swedens most popular bands at the time, and Fredriksson in the less successful Strul and MaMas Barn before both embarked on solo careers. In 1981, Fredriksson sang for the first time with Gyllene Tider on stage and was featured as a background vocalist for a Swedish-language album the band released in 1982. Gessle also worked with ex-ABBA singer Frida, for a song that appeared on her 1982 album Somethings Going On, while working on her first solo album, Het vind, Fredriksson performed more background vocals for Gyllene Tiders only album in English, The Heartland Café. The 11-track album was released in February 1984 and sold 45,000 copies in Sweden, According to Gessle, the groups first English-language release was in response to interest expressed by EMIs American label Capitol Records. Capitol took six of the tracks and released an extended play record in the US with a title, Heartland. Gessle and the members of Gyllene Tider chose the title of a 1975 Dr. Feelgood song. The newly named Roxette issued one near-invisible release in the US, Teaser Japanese, whose video reached MTVs studio and it, and subsequent singles, fared better in Sweden, and Gyllene Tider briefly toured the country to support the album. However, the album died soon enough and the international career died before it even started and we decided to put Gyllene Tider to rest. Gessle then turned solo work, recording his second Swedish-language solo album, Scener, released in 1985, while Fredriksson recorded her second solo album, Den sjunde vågen

Compact Cassette
–
The Compact Cassette or Musicassette, also commonly called cassette tape, audio cassette, or simply tape or cassette, is an analog magnetic tape recording format for audio recording and playback. It was released by Philips in 1962, having developed in Hasselt. Compact cassettes come in two forms, either already containing content as a cassette, or as a fully recordable blank cassette. Its uses ranged from portable audio to home recording to data storage for early microcomputers, the first cassette player designed for use in car dashes was introduced in 1968. Between the early 1970s and the early 2000s, the cassette was one of the two most common formats for prerecorded music, first alongside the LP record and later the compact disc. Compact Cassettes contain two miniature spools, between which a magnetically coated, polyester-type plastic film is passed and wound and these spools and their attendant parts are held inside a protective plastic shell. This reversal is achieved either by flipping the cassette, or by having the machine itself change the direction of tape movement. In 1935, decades before the introduction of the Compact Cassette, AEG released the first reel-to-reel tape recorder and it was based on the invention of the magnetic tape by Fritz Pfleumer, which used similar technology but with open reels. These instruments were expensive and relatively difficult to use and were therefore used mostly by professionals in radio stations. In 1958, following four years of development, RCA Victor introduced the stereo, quarter-inch, reversible, however, it was a large cassette, and offered few pre-recorded tapes. Despite the multiple versions, it failed, consumer use of tape only took off in the early 1960s, after playback machines reached a comfortable, user-friendly design. This was achieved primarily by the introduction of transistors which replaced the bulky, fragile, reel-to-reel tape then became more suitable to household use, but still remained an esoteric product. The team at Philips was led by Lou Ottens in Hasselt, Philips was competing with Telefunken and Grundig in a race to establish its cassette tape as the worldwide standard, and it wanted support from Japanese electronics manufacturers. However, the Philips Compact Cassette became dominant as a result of Philips decision to license the format free of charge, Philips also released the Norelco Carry-Corder 150 recorder/player in the US in November 1964. By 1966 over 250,000 recorders had been sold in the US alone, by 1968,85 manufacturers had sold over 2.4 million players. By the end of the 1960s, the business was worth an estimated 150 million dollars. In the early years sound quality was mediocre, but it improved dramatically by the early 1970s when it caught up with the quality of 8-track tape, the Compact Cassette went on to become a popular alternative to the 12-inch vinyl LP during the late 1970s. The mass production of blank Compact Cassettes began in 1964 in Hanover, prerecorded music cassettes were launched in Europe in late 1965

Recording studio
–
A recording studio is a facility for sound recording and mixing. Ideally both the recording and monitoring spaces are designed by an acoustician or audio engineer to achieve optimum acoustic properties. The engineers and producers listen to the music and the recorded tracks on monitor speakers and/or headphones. Major recording studios typically have a range of large, heavy, Isolation booths are small sound-insulated rooms with doors, designed for instrumentalists. This equipment may interfere with the recording process, Recording studios are carefully designed around the principles of room acoustics to create a set of spaces with the acoustical properties required for recording sound with precision and accuracy. This will consist of both room treatment and soundproofing to prevent sound from leaving the property. Even though sound isolation is a key goal, the musicians, singers, audio engineers and record producers still need to be able to see other, to see cue gestures. As such, the room, isolation booths, vocal booths. Some smaller studios do not have instruments, and bands and artists are expected to bring their own instruments, having musical instruments and equipment in the studio creates additional costs for a studio, as pianos have to be tuned and instruments need to be maintained. However, it makes it convenient for recording artists, as they do not have to bring in large. As well, less costly studio time is spent moving in gear, drummers bring their own snare drum, cymbals and sticks/brushes. The types and brands of equipment owned by a studio depends on the styles of music for the bands. A studio that mainly records heavy metal music will be likely to have large, powerful guitar amp heads, in contrast, a studio which mainly records country bands will likely have a selection of small, vintage combo amps. A studio that records a lot of 1970s-style funk may have an electric piano. General purpose computers have rapidly assumed a role in the recording process. A computer thus outfitted is called a Digital Audio Workstation, or DAW, other software applications include Ableton Live, Mixcraft, Cakewalk Sonar, ACID Pro, FL Studio, Adobe Audition, Auto-Tune, Audacity, and Ardour. While Apple Macintosh is used for most studio work, there is a breadth of available for Microsoft Windows. If no mixing console is used and all mixing is done using only a keyboard and mouse, the OTB is used when mixing with other hardware and not just the PC software

Stockholm
–
The city is spread across 14 islands on the coast in the southeast of Sweden at the mouth of Lake Mälaren, by the Stockholm archipelago and the Baltic Sea. The area has settled since the Stone Age, in the 6th millennium BC. It is also the capital of Stockholm County, Stockholm is the cultural, media, political, and economic centre of Sweden. The Stockholm region alone accounts for over a third of the countrys GDP and it is an important global city, and the main centre for corporate headquarters in the Nordic region. The city is home to some of Europes top ranking universities, such as the Stockholm School of Economics, Karolinska Institute and it hosts the annual Nobel Prize ceremonies and banquet at the Stockholm Concert Hall and Stockholm City Hall. One of the citys most prized museums, the Vasa Museum, is the most visited museum in Scandinavia. The Stockholm metro, opened in 1950, is known for its decoration of the stations. Swedens national football arena is located north of the city centre, Ericsson Globe, the national indoor arena, is in the southern part of the city. The city was the host of the 1912 Summer Olympics, and hosted the equestrian portion of the 1956 Summer Olympics otherwise held in Melbourne, Victoria, Australia. Stockholm is the seat of the Swedish government and most of its agencies, including the highest courts in the judiciary, and the official residencies of the Swedish monarch and the Prime Minister. The government has its seat in the Rosenbad building, the Riksdag is seated in the Parliament House, and the Prime Ministers residence is adjacent at the Sager House. After the Ice Age, around 8,000 BCE, there were already a number of people living in the present-day Stockholm area. Thousands of years later, as the ground thawed, the climate became tolerable, at the intersection of the Baltic Sea and lake Mälaren is an archipelago site where the Old Town of Stockholm was first built from about 1000 CE by Vikings. They had a positive impact on the area because of the trade routes they created. Stockholms location appears in Norse sagas as Agnafit, and in Heimskringla in connection with the legendary king Agne, the earliest written mention of the name Stockholm dates from 1252, by which time the mines in Bergslagen made it an important site in the iron trade. The first part of the name means log in Swedish, although it may also be connected to an old German word meaning fortification, the second part of the name means islet, and is thought to refer to the islet Helgeandsholmen in central Stockholm. Stockholms core, the present Old Town was built on the island next to Helgeandsholmen from the mid 13th century onward. The city originally rose to prominence as a result of the Baltic trade of the Hanseatic League, Stockholm developed strong economic and cultural linkages with Lübeck, Hamburg, Gdańsk, Visby, Reval, and Riga during this time

YouTube
–
YouTube is an American video-sharing website headquartered in San Bruno, California. The service was created by three former PayPal employees—Chad Hurley, Steve Chen, and Jawed Karim—in February 2005, Google bought the site in November 2006 for US$1.65 billion, YouTube now operates as one of Googles subsidiaries. Unregistered users can watch videos on the site, while registered users are permitted to upload an unlimited number of videos. Videos deemed potentially offensive are available only to registered users affirming themselves to be at least 18 years old, YouTube earns advertising revenue from Google AdSense, a program which targets ads according to site content and audience. YouTube was founded by Chad Hurley, Steve Chen, and Jawed Karim, Hurley had studied design at Indiana University of Pennsylvania, and Chen and Karim studied computer science together at the University of Illinois at Urbana-Champaign. Karim could not easily find video clips of either event online, Hurley and Chen said that the original idea for YouTube was a video version of an online dating service, and had been influenced by the website Hot or Not. YouTube began as a venture capital-funded technology startup, primarily from an $11.5 million investment by Sequoia Capital between November 2005 and April 2006, YouTubes early headquarters were situated above a pizzeria and Japanese restaurant in San Mateo, California. The domain name www. youtube. com was activated on February 14,2005, the first YouTube video, titled Me at the zoo, shows co-founder Jawed Karim at the San Diego Zoo. The video was uploaded on April 23,2005, and can still be viewed on the site, YouTube offered the public a beta test of the site in May 2005. The first video to reach one million views was a Nike advertisement featuring Ronaldinho in November 2005. Following a $3.5 million investment from Sequoia Capital in November, the site grew rapidly, and in July 2006 the company announced that more than 65,000 new videos were being uploaded every day, and that the site was receiving 100 million video views per day. The site has 800 million unique users a month and it is estimated that in 2007 YouTube consumed as much bandwidth as the entire Internet in 2000. The choice of the name www. youtube. com led to problems for a similarly named website, the sites owner, Universal Tube & Rollform Equipment, filed a lawsuit against YouTube in November 2006 after being regularly overloaded by people looking for YouTube. Universal Tube has since changed the name of its website to www. utubeonline. com, in October 2006, Google Inc. announced that it had acquired YouTube for $1.65 billion in Google stock, and the deal was finalized on November 13,2006. In March 2010, YouTube began free streaming of certain content, according to YouTube, this was the first worldwide free online broadcast of a major sporting event. On March 31,2010, the YouTube website launched a new design, with the aim of simplifying the interface, Google product manager Shiva Rajaraman commented, We really felt like we needed to step back and remove the clutter. In May 2010, YouTube videos were watched more than two times per day. This increased to three billion in May 2011, and four billion in January 2012, in February 2017, one billion hours of YouTube was watched every day

Electric guitar
–
The vibrations of the strings are sensed by a pickup, of which the most common type is the magnetic pickup, which uses the principle of direct electromagnetic induction. The signal generated by a guitar is too weak to drive a loudspeaker, so it is plugged into a guitar amplifier before being sent to a loudspeaker. The output of a guitar is an electric signal. Invented in 1931, the electric guitar was adopted by jazz guitarists. Early proponents of the guitar on record included Les Paul, Lonnie Johnson, Sister Rosetta Tharpe, T-Bone Walker. During the 1950s and 1960s, the guitar became the most important instrument in pop music. It has evolved into an instrument that is capable of a multitude of sounds and styles in genres ranging from pop and rock to country music, blues and jazz. It served as a component in the development of electric blues, rock and roll, rock music, heavy metal music. Electric guitar design and construction vary greatly in the shape of the body and the configuration of the neck, bridge, Guitars may have a fixed bridge or a spring-loaded hinged bridge that lets players bend the pitch of notes or chords up or down or perform vibrato effects. The sound of a guitar can be modified by new playing techniques such as string bending, tapping, hammering on, using audio feedback, in a small group, such as a power trio, one guitarist switches between both roles. In larger rock and metal bands, there is often a rhythm guitarist, many experiments at electrically amplifying the vibrations of a string instrument were made dating back to the early part of the 20th century. Patents from the 1910s show telephone transmitters were adapted and placed inside violins, hobbyists in the 1920s used carbon button microphones attached to the bridge, however, these detected vibration from the bridge on top of the instrument, resulting in a weak signal. With numerous people experimenting with electrical instruments in the 1920s and early 1930s, Electric guitars were originally designed by acoustic guitar makers and instrument manufacturers. Some of the earliest electric guitars adapted hollow-bodied acoustic instruments and used tungsten pickups, the first electrically amplified guitar was designed in 1931 by George Beauchamp, the general manager of the National Guitar Corporation, with Paul Barth, who was vice president. The maple body prototype for the one-piece cast aluminum frying pan was built by Harry Watson, commercial production began in late summer of 1932 by the Ro-Pat-In Corporation, in Los Angeles, a partnership of Beauchamp, Adolph Rickenbacker, and Paul Barth. In 1934, the company was renamed the Rickenbacker Electro Stringed Instrument Company, in that year Beauchamp applied for a United States patent for an Electrical Stringed Musical Instrument and the patent was issued in 1937. The Electro-Spanish Ken Roberts provided players a full 25 scale, with 17 frets free of the fretboard and it is estimated that fewer than 50 Electro-Spanish Ken Roberts were constructed between 1933 and 1937, fewer than 10 are known to survive today. The need for the guitar became apparent during the big band era as orchestras increased in size, particularly when acoustic guitars had to compete with large

Harmonica
–
There are many types of harmonica, including diatonic, chromatic, tremolo, octave, orchestral, and bass versions. A harmonica is played by using the mouth to direct air into or out of one or more holes along a mouthpiece, behind each hole is a chamber containing at least one reed. A harmonica reed is a flat elongated spring typically made of brass, stainless steel, or bronze, when the free end is made to vibrate by the players air, it alternately blocks and unblocks the airway to produce sound. Reeds are pre-tuned to individual pitches, tuning may involve changing a reeds length, the weight near its free end, or the stiffness near its fixed end. Longer, heavier and springier reeds produce deeper, lower sounds, an important technique in performance is bending, causing a drop in pitch by making embouchure adjustments. Such two-reed pitch changes actually involve sound production by the normally silent reed, the basic parts of the harmonica are the comb, reed plates and cover plates. The comb is the body of the instrument, which. The term comb may originate from the similarity between this part of a harmonica and a hair comb, Harmonica combs were traditionally made from wood but now are also made from plastic or metal. Some modern and experimental designs are complex in the way that they direct the air. There is dispute among players about whether comb material affects the tone of a harmonica, among those saying yes are those who are convinced by their ears. Few dispute, however, that comb surface smoothness and air-tightness when mated with the reedplates can greatly affect tone, the main advantage of a particular comb material over another one is its durability. In particular, a comb can absorb moisture from the players breath. This can cause the comb to expand slightly, making the instrument uncomfortable to play, various types of wood and treatments have been devised to reduce the degree of this problem. Much effort is devoted by serious players to restoring wood combs, some players used to soak wooden-combed harmonicas in water to cause a slight expansion, which they intended to make the seal between the comb, reed plates and covers more airtight. Modern wooden-combed harmonicas are less prone to swelling and contracting, players still dip harmonicas in water for the way it affects tone and ease of bending notes. The reed plate is a grouping of several reeds in a single housing, the reeds are usually made of brass, but steel, aluminium and plastic are occasionally used. Individual reeds are usually riveted to the plate, but they may also be welded or screwed in place. Reeds fixed on the side of the reed plate respond to blowing

Capitol Records
–
Capitol Records, LLC is an American record label which operates as a division of the Capitol Music Group. The label was founded as the first West Coast-based record label in the United States in 1942 by three industry insiders named Johnny Mercer, Buddy DeSylva and Glenn Wallichs, in 1955, the label was acquired by the British music conglomerate EMI as its North American subsidiary. EMI was later acquired by Universal Music Group in 2012 and was merged with the company in 2013, making Capitol Records, Capitol Records circular headquarter building located in Los Angeles is a recognized landmark of California. Mercer first raised the idea of starting a company while golfing with Harold Arlen. By 1941, Mercer was a songwriter and a singer with multiple successful releases. Mercer next suggested the idea to Wallichs while visiting his record store, Wallichs expressed interest in the idea and the pair negotiated an agreement whereby Mercer would run the company and identify their artists, while Wallichs managed the business side. On February 2,1942, Mercer and Wallichs met with DeSylva at a Hollywood restaurant to inquire about the possibility of investment of the company from Paramount Pictures, while DeSylva declined the proposal, he handed the pair a check worth $15,000. On March 27,1942, the three men incorporated as Liberty Records, in May 1942, the application was amended to change the companys name to Capitol Records. On April 6,1942, Mercer supervised Capitols first recording session where Martha Tilton recorded the song Moon Dreams, on May 5, Bobby Sherwood and his orchestra recorded two tracks in the studio. On May 21, Freddie Slack and his orchestra recorded three tracks in the studio, one with the orchestra, one with Ella Mae Morse called Cow-Cow Boogie, on June 4,1942, Capitol opened its first office in a second-floor room south of Sunset Boulevard. On that same day, Wallichs presented the companys first free record to Los Angeles disc jockey Peter Potter, on June 5,1942, Paul Whiteman and his Orchestra recorded four songs at the studio. On June 12, the recorded five more songs in the studio. On June 11, Tex Ritter recorded Jingle Jangle Jingle and Goodbye My Little Cherokee for his first Capitol recording session, and the songs formed Capitols 110th produced record. 133 - Get On Board Little Chillun - July 31,1942 - is a Freddie Slack/Ella Mae Morse/Mellowaires recording that might be the first rock n roll record and she has sometimes been called the first rock n roll singer. A good example is her 1942 recording of song which, with strong gospel, blues, boogie. Bone Walker recorded Mean Old World a pioneering example of the use of electric guitar. The earliest recording artists included co-owner Mercer, Whiteman, Tilton, Morse, Margaret Whiting, Jo Stafford, the Pied Pipers, Johnnie Johnston, Tex Ritter, Capitols first gold single was Morses Cow Cow Boogie in 1942. Capitols first album was Capitol Presents Songs By Johnny Mercer, a three 78-rpm disc set with recordings by Mercer, Stafford and the Pied Pipers, all with Westons Orchestra

Record producer
–
A record producer or music producer oversees and manages the sound recording and production of a band or performers music, which may range from recording one song to recording a lengthy concept album. A producer has many roles during the recording process, the roles of a producer vary. The producer may perform these roles himself, or help select the engineer, the producer may also pay session musicians and engineers and ensure that the entire project is completed within the record companies budget. A record producer or music producer has a broad role in overseeing and managing the recording. Producers also often take on an entrepreneurial role, with responsibility for the budget, schedules, contracts. In the 2010s, the industry has two kinds of producers with different roles, executive producer and music producer. Executive producers oversee project finances while music producers oversee the process of recording songs or albums. In most cases the producer is also a competent arranger, composer. The producer will also liaise with the engineer who concentrates on the technical aspects of recording. Noted producer Phil Ek described his role as the person who creatively guides or directs the process of making a record, indeed, in Bollywood music, the designation actually is music director. The music producers job is to create, shape, and mold a piece of music, at the beginning of record industry, producer role was technically limited to record, in one shot, artists performing live. The role of producers changed progressively over the 1950s and 1960s due to technological developments, the development of multitrack recording caused a major change in the recording process. Before multitracking, all the elements of a song had to be performed simultaneously, all of these singers and musicians had to be assembled in a large studio and the performance had to be recorded. As well, for a song that used 20 instruments, it was no longer necessary to get all the players in the studio at the same time. Examples include the rock sound effects of the 1960s, e. g. playing back the sound of recorded instruments backwards or clanging the tape to produce unique sound effects. These new instruments were electric or electronic, and thus they used instrument amplifiers, new technologies like multitracking changed the goal of recording, A producer could blend together multiple takes and edit together different sections to create the desired sound. For example, in jazz fusion Bandleader-composer Miles Davis album Bitches Brew, producers like Phil Spector and George Martin were soon creating recordings that were, in practical terms, almost impossible to realise in live performance. Producers became creative figures in the studio, other examples of such engineers includes Joe Meek, Teo Macero, Brian Wilson, and Biddu

Acoustic guitar
–
An acoustic guitar is a guitar that produces sound acoustically—by transmitting the vibration of the strings to the air—as opposed to relying on electronic amplification. The sound waves from the strings of an acoustic guitar resonate through the guitars body and this typically involves the use of a sound board and a sound box to strengthen the vibrations of the strings. The main source of sound in a guitar is the string. The string vibrates at a frequency and also creates many harmonics at various different frequencies. The frequencies produced can depend on string length, mass, gitterns, a small plucked guitar were the first small guitar-like instruments created during the Middle Ages with a round back like that of a lute. Modern guitar shaped instruments were not seen until the Renaissance era where the body, the earliest string instruments that related to the guitar and its structure where broadly known as the vihuelas within Spanish musical culture. Vihuelas where string instruments that were seen in the 16th century during the Renaissance. Later, Spanish writers distinguished these instruments into 2 categories of vihuelas, the vihuela de arco was an instrument that mimicked the violin, and the vihuela de penola was played with a plectrum or by hand. When it was played by hand it was known as the vihuela de mano, vihuela de mano shared extreme similarities with the Renaissance guitar as it used hand movement at the sound hole or sound chamber of the instrument to create music. The real production of guitars kicked off in France where the popularity, the production became so large that early famous creators such as Gaspard Duyffooprucgars instruments were being sold as copies by other guitar makers in Lyon. Benoist Lejeune, a maker, offered and sold guitar copies of Duyffoprucgars instruments and was later imprisoned for using his mark and work. During this time, the production was increasing tremendously but it was not until Robert and Claude Denis appeared overproducing the early Renaissance guitar in Paris, as father and son, Robert and Claude produced hundreds of guitars that increased the popularity of the instrument greatly. Because of them and the great many guitar inventors of this time, by 1790 only six-course vihuela guitars were being created and had become the main type and model of guitar used in Spain. Most of the older 5-course guitars where still in use but were also being modified to a six-coursed acoustical guitar, by the 19th century, coursed strings where evolved into 6 single-stringed instruments much like that of the guitar today. It had evolved into the modern look except for size, retaining a smaller frame, the acoustic guitars soundboard, or top, also has a strong effect on the loudness of the guitar. No amplification actually occurs in this process, because no energy is added to increase the loudness of the sound. All the energy is provided by the plucking of the string, but without a soundboard, the string would just cut through the air without actually moving it much. The soundboard increases the surface of the area in a process called mechanical impedance matching

Audio engineer
–
An audio engineer works on the recording, manipulating the record using equalization and electronic effects, mixing, reproduction, and reinforcement of sound. Audio engineers work on the. technical aspect of recording—the placing of microphones, pre-amp knobs, the physical recording of any project is done by an engineer. Many audio engineers creatively use technologies to produce sound for film, radio, television, music, electronic products and computer games. Audio engineers also set up, sound check and do live sound mixing using an audio console, research and development audio engineers invent new technologies, equipment and techniques, to enhance the process and art of audio engineering. They might also be referred to as acoustic engineers, audio engineers in research and development usually possess a bachelors degree, masters degree or higher qualification in acoustics, physics, computer science or another engineering discipline. They might work in consultancy, specializing in architectural acoustics. Alternatively they might work in companies, or other industries that need audio expertise. Some positions, such as faculty require a Doctor of Philosophy, in Germany a Toningenieur is an audio engineer who designs, builds and repairs audio systems. The listed subdisciplines are based on PACS coding used by the Acoustical Society of America with some revision, audio engineers develop algorithms to allow the electronic manipulation of audio signals. These can be processed at the heart of audio production such as reverberation. Alternatively, the algorithms might carry out echo cancellation on Skype, or identify, architectural acoustics is the science and engineering of achieving a good sound within a room. For audio engineers, architectural acoustics can be about achieving good speech intelligibility in a stadium or enhancing the quality of music in a theatre, architectural Acoustic design is usually done by acoustic consultants. Electroacoustics is concerned with the design of headphones, microphones, loudspeakers, sound reproduction systems, examples of electroacoustic design include portable electronic devices, sound systems in architectural acoustics, surround sound in movie theater and vehicle audio. Musical acoustics is concerned with researching and describing the science of music, in audio engineering, this includes the design of electronic instruments such as synthesizers, the human voice, computer analysis of audio, music therapy, and the perception and cognition of music. Psychoacoustics is the study of how humans respond to what they hear. At the heart of audio engineering are listeners who are the final arbitrator as to whether a design is successful. The production, computer processing and perception of speech is an important part of audio engineering, ensuring speech is transmitted intelligibly, efficiently and with high quality, in rooms, through public address systems and through mobile telephone systems are important areas of study. Producer, engineer, and mixer Phil Ek has described audio engineering as the aspect of recording—the placing of microphones, the turning of pre-amp knobs

Single (music)
–
In music, a single or record single is a type of release, typically a song recording of fewer tracks than an LP record, an album or an EP record. This can be released for sale to the public in a variety of different formats, in most cases, a single is a song that is released separately from an album, although it usually also appears on an album. Typically, these are the songs from albums that are released separately for promotional uses such as digital download or commercial radio airplay and are expected to be the most popular, in other cases a recording released as a single may not appear on an album. As digital downloading and audio streaming have become prevalent, it is often possible for every track on an album to also be available separately. Nevertheless, the concept of a single for an album has been retained as an identification of a heavily promoted or more popular song within an album collection. Despite being referred to as a single, singles can include up to as many as three tracks on them. The biggest digital music distributor, iTunes, accepts as many as three tracks less than ten minutes each as a single, as well as popular music player Spotify also following in this trend. Any more than three tracks on a release or longer than thirty minutes in total running time is either an Extended Play or if over six tracks long. The basic specifications of the single were made in the late 19th century. Gramophone discs were manufactured with a range of speeds and in several sizes. By about 1910, however, the 10-inch,78 rpm shellac disc had become the most commonly used format, the inherent technical limitations of the gramophone disc defined the standard format for commercial recordings in the early 20th century.26 rpm. With these factors applied to the 10-inch format, songwriters and performers increasingly tailored their output to fit the new medium, the breakthrough came with Bob Dylans Like a Rolling Stone. Singles have been issued in various formats, including 7-inch, 10-inch, other, less common, formats include singles on digital compact cassette, DVD, and LD, as well as many non-standard sizes of vinyl disc. Some artist release singles on records, a more common in musical subcultures. The most common form of the single is the 45 or 7-inch. The names are derived from its speed,45 rpm. The 7-inch 45 rpm record was released 31 March 1949 by RCA Victor as a smaller, more durable, the first 45 rpm records were monaural, with recordings on both sides of the disc. As stereo recordings became popular in the 1960s, almost all 45 rpm records were produced in stereo by the early 1970s
