Noise (radio)

In radio reception, noise is the superposition of white noise and other disturbing influences on the signal, caused either by thermal noise and other electronic noise from receiver input circuits or by interference from radiated electromagnetic noise picked up by the receiver's antenna. If no noise were picked up with radio signals, even weak transmissions could be received at virtually any distance by making a radio receiver that was sensitive enough. In practice, this doesn't work, and a point is reached where the only way to extend the range of a transmission is to increase the transmitter power.

Thermal noise can be made lower by cooling the circuits, but this is only usually worthwhile on radio telescopes. In other applications the limiting noise source depends on the frequency range in use. At low frequencies (longwave or mediumwave) and at high frequencies (shortwave), interference caused by lightning or by nearby electrical impulses in electrical switches, motors, vehicle ignition circuits, computers, and other man-made sources tends to swamp transmissions with thermal noise. These noises are often referred to as static. Atmospheric noise is radio noise caused by natural atmospheric processes, primarily lightning discharges in thunderstorms. At very high frequency and ultra high frequency these sources can still be important, but at a much lower level, such that thermal noise is usually the limiting factor. Cosmic background noise is experienced at frequencies above about 15 MHz when highly directional antennas are pointed toward the sun or to certain other regions of the sky such as the center of the Milky Way Galaxy.

Noise (company)

Noise Inc. (株式会社ノイズ) is a video game development company that works in partnership with Nintendo, developing games for the Custom Robo series.

History

Noise was founded with a staff of 10 people on September 2, 1996 for the original purpose of developing games for PCs. A short time after, Noise became a part of Marigul Management, a company created by Nintendo and the Japanese telecommunications company Recruit for the purpose of enlisting smaller developers to make original games for the Nintendo 64.

The company’s first commercially published game, Custom Robo for the Nintendo 64, was released in Japan on December 9, 1999 and became a commercial success in Japan, prompting Nintendo to formally enter a publishing agreement with Noise. In 2006, Custom Robo was released in China for the iQue Player, making it the only Custom Robo title ever to be released there.

Their second released title was Custom Robo V2, which was released on November 10, 2000 and was also met with commercial success in Japan. They also released their first portable video game for the Game Boy Advance, Custom Robo GX, on July 26, 2002.

Noise (audio)

Noise in audio, recording, and broadcast systems refers to the residual low level sound (usually hiss and hum) that is heard in quiet periods of a program.

In audio engineering it can refer either to the acoustic noise from loudspeakers, or to the unwanted residual electronic noise signal that gives rise to acoustic noise heard as 'hiss'. This signal noise is commonly measured using A-weighting or ITU-R 468 weighting

Noise is often generated deliberately and used as a test signal. Two types of deliberately generated noise in common use are referred to as 'white noise', which has a uniform spectral power density at all frequencies, or 'pink noise' which has a power spectral density that falls at 3dB/octave with rising frequency. The latter is often more useful in audio testing because it contains constant energy per octave (and hence per commonly used 1/3rd octave), rather than a prepondance of energy at high frequencies. In other words it contains energy that is distributed geometrically rather than linearly.

Noise (2007 Australian film)

Noise is a 2007 Australian drama-thriller film written and directed by director Matthew Saville. The film stars Brendan Cowell, Henry Nixon, Luke Elliot, Katie Wall, Maia Thomas and Nicholas Bell.

Plot

The film is set up amongst the landscape of two potentially related murders: that of an engaged woman in Sunshine, and that of seven passengers on a train in Melbourne's inner west. From there, the film deals primarily with the experiences of Lavinia Smart, a young woman who boarded the train shortly after the murders, and police Constable Graham McGahan, who is afflicted with increasingly severe tinnitus. When he requests light duty on account of his tinnitus, Constable McGahan is assigned the night shift of a police information van in the inner-western Melbourne suburb of Sunshine, where he encounters the traumatized members of the local community, including Lucky Phil, a mentally handicapped man, and Dean Stouritis, the fiance of the slain woman.

At the same time, the film explores the fear Lavinia experiences after the horrific events she witnessed. Although she escapes with her life, the police are unsatisfied with her statements and accuse her of holding back information. Lavinia is further traumatized when she realizes that the killer has stolen a portrait that can be used to identify her. The police try to reassure her of her safety, but a man she identified in a police lineup easily tracks her down and tries to intimidate her. After Lavinia angrily confronts him and explains her situation, he apologizes and gives her a ride back to her house.

Born to Die (Lana Del Rey album)

Born to Die is the second studio album and major-label debut by American singer and songwriter Lana Del Rey. It was released on January 27, 2012 by Interscope Records, Polydor Records, and Stranger Records. Del Rey collaborated with producers including Patrik Berger, Jeff Bhasker, Chris Braide, Emile Haynie, Justin Parker, Rick Nowels, Robopop, and Al Shux to achieve her desired sound. Their efforts resulted in a primarily baroque pop record, which sees additional influences from alternative hip hop, indie pop and trip hop music.

Contemporary music critics were divided in their opinions of Born to Die; some commended its distinctive production, while its repetitiveness and melodramatic tendencies were a recurring complaint. The record debuted at number two on the U.S. Billboard 200 with first-week sales of 77,000 copies; it was later certified platinum by the Recording Industry Association of America (RIAA) after moving one million units. Born to Die reached the peak position on eleven international record charts, and has sold 8.5 million copies worldwide as of May 2015.

Radio (Darius Rucker song)

"Radio" is a song co-written and recorded by American country music artist Darius Rucker. It was released on July 22, 2013 as the third single from his album True Believers. Rucker wrote the song with Luke Laird and Ashley Gorley.

Content

The song is a reflection on the narrator's teenage years: specifically, of borrowing his mother's car to take his girlfriend for a ride, and listening to songs on the radio while doing so.

Critical reception

The song generally received favorable reviews. Bobby Peacock of Roughstock gave the song four and a half stars out of five, saying that "it sounds like the kind of fun song you would want to hear on the radio at a memorable moment." Peacock praised Rucker's "all-smiles delivery" and the song's "incredibly catchy melody and tight production." He also compared its theme to "I Watched It All (On My Radio)" by Lionel Cartwright. Tammy Ragusa of Country Weekly gave the song an A grade, calling it "the perfect marriage of an artist’s effervescent personality with an upbeat song, this one about the love of music." Billy Dukes of Taste of Country gave the song two and a half stars out of five, writing that "the uptempo tribute to young love, open roads and, of course, the radio is familiar and easy to fall for, especially when powered by Rucker’s unequaled exuberance." However, Dukes also called the song "a little fluffy" and "not difficult to forget."

Radioactive (Yelawolf album)

Radioactive (also known as Radioactive: Amazing and Mystifying Chemical Tricks) is the debut studio album by American rapper Yelawolf; it was released on November 21, 2011, by Shady Records and Interscope Records.

Recording

Recording sessions took place at Las Vegas Valley, Nevada in two weeks.

Music composition, style, and lyrics

Radioactive covers many different styles of hip hop fusions, being alternative hip hop as principal musical genre. Hardcore hip hop is represented on the tracks "Radioactive Introduction", "Throw It Up", "Get Away", and "Slumerican Shitizen". A horrorcore rap style is used in "Growin' Up in the Gutter", whereas "Hard White (Up in the Club)" is a crunk party track. "Let's Roll", "Write Your Name", and "Radio" follow a pop rap style, with catchy hooks and beats. "Animal" is a fast-paced hip hop party track with a dubstep influenced beat. "Good Girl" utilizes an R&B-tinged feel, while "The Hardest Love Song in the World" is a g-funk hip hop track. Yelawolf covers a variety of lyrical themes in these album, from gangsta rap lyrics in "Get Away" and "Throw It Up", to more conscious and slightly political tracks such as "Made in the USA", "Slumerican Shitizen", "Write Your Name", and "The Last Song". "Radio" is about the internet taking over how music and music videos are received by fans. It also refers to radio stations playing the same songs constantly and singers being discovered via the internet. The song contains several references to rock and rap artists and their songs from the past. The album's final track, titled "The Last Song" described as very personal about Yelawolf's life, and it's a very emotional final letter to his absent biological father and talks about other past struggles.
