THX 1138 4EB
THX Ltd. is an American company that develops the eponymous high fidelity audio/visual reproduction standards for movie theaters, screening rooms, home theaters, computer speakers, gaming consoles, car audio systems, and video games. Founded on May 20, 1983 by George Lucas and headquartered in San Francisco, California, it is currently a subsidiary of Razer Inc. THX was developed by Tomlinson Holman at Lucas's company Lucasfilm in 1983 to ensure that the soundtrack for the third ''Star Wars'' film, ''Return of the Jedi'', would be accurately reproduced in the best venues. THX was named after Holman's initials, with the "X" standing for "crossover" or "experiment"; the name is also an homage to Lucas's first film, ''THX 1138'' (1971). The distinctive glissando up from a rumbling low pitch used in the THX trailers, created by Holman's co-worker James A. Moorer, is known as the "Deep Note". The THX system is a quality assurance system, not a recording technology. All sound reco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subsidiary
A subsidiary, subsidiary company or daughter company is a company owned or controlled by another company, which is called the parent company or holding company. Two or more subsidiaries that either belong to the same parent company or having a same management being substantially controlled by same entity/group are called sister companies. The subsidiary can be a company (usually with limited liability) and may be a government- or state-owned enterprise. They are a common feature of modern business life, and most multinational corporations organize their operations in this way. Examples of holding companies are Berkshire Hathaway, Jefferies Financial Group, The Walt Disney Company, Warner Bros. Discovery, or Citigroup; as well as more focused companies such as IBM, Xerox, and Microsoft. These, and others, organize their businesses into national and functional subsidiaries, often with multiple levels of subsidiaries. Details Subsidiaries are separate, distinct legal entit ...

Computer Speaker
Computer speakers, or multimedia speakers, are speakers sold for use with computers, although usually capable of other audio uses, e.g. for an MP3 player A portable media player (PMP) (also including the related digital audio player (DAP)) is a portable consumer electronics device capable of storing and playing digital media such as audio, images, and video files. The data is typically stored o .... Most such speakers have an internal amplifier and consequently require a power source, which may be by a mains power supply often via an AC adapter, batteries, or a USB port. The signal input connector is often a 3.5 mm jack plug (usually color-coded lime green per the PC 99 standard); RCA connectors are sometimes used, and a USB port may supply both signal and power (requiring additional circuitry, and only suitable for use with a computer). Battery-powered wireless Bluetooth speakers require no connections at all. Most computers have speakers of low power and qualit ...

Recording Technology
Sound recording and reproduction is the electrical, mechanical, electronic, or digital inscription and re-creation of sound waves, such as spoken voice, singing, instrumental music, or sound effects. The two main classes of sound recording technology are analog recording and digital recording. Sound recording is the transcription of invisible vibrations in air onto a storage medium such as a phonograph disc. The process is reversed in sound reproduction, and the variations stored on the medium are transformed back into sound waves. Acoustic analog recording is achieved by a microphone diaphragm that senses changes in atmospheric pressure caused by acoustic sound waves and records them as a mechanical representation of the sound waves on a medium such as a phonograph record (in which a stylus cuts grooves on a record). In magnetic tape recording, the sound waves vibrate the microphone diaphragm and are converted into a varying electric current, which is then converted to a v ...

Quality Assurance
Quality assurance (QA) is the term used in both manufacturing and service industries to describe the systematic efforts taken to ensure that the product(s) delivered to customer(s) meet with the contractual and other agreed upon performance, design, reliability, and maintainability expectations of that customer. The core purpose of Quality Assurance is to prevent mistakes and defects in the development and production of both manufactured products, such as automobiles and shoes, and delivered services, such as automotive repair and athletic shoe design. Assuring quality and therefore avoiding problems and delays when delivering products or services to customers is what ISO 9000 defines as that "part of quality management focused on providing confidence that quality requirements will be fulfilled". This defect prevention aspect of quality assurance differs from the defect detection aspect of quality control and has been referred to as a ''shift left'' since it focuses on quality eff ...

Deep Note
file:Deep Note Internet Archive.png, Waveform of the Deep Note The Deep Note is the sound trademark of THX, THX Ltd., being a distinctive audio synthesis, synthesized crescendo that glissandos from a relatively narrow frequency spread (about 200–400 Hz) to a broader frequency spread (of about three octaves). It was created by James A. Moorer, a former employee of Lucasfilm's Computer Division in late 1982. The sound is used on trailer (movie), trailers for THX-certified movie theaters, home video releases, video games, and in-car entertainment systems. The Deep Note was partially previewed on the opening track of the 1983 album ''The Digital Domain: A Demonstration,'' where it was included among sound effects that were combined with the Deep Note itself. The Deep Note debuted later that same year at the premiere of ''Return of the Jedi'' in Los Angeles.

Glissando
In music, a glissando (; plural: ''glissandi'', abbreviated ''gliss.'') is a glide from one pitch to another (). It is an Italianized musical term derived from the French ''glisser'', "to glide". In some contexts, it is distinguished from the continuous portamento. Some colloquial equivalents are slide, sweep (referring to the "discrete glissando" effects on guitar and harp, respectively), bend, smear, rip (for a loud, violent gliss to the beginning of a note), lip (in jazz terminology, when executed by changing one's embouchure on a wind instrument), plop, or falling hail (a glissando on a harp using the back of the fingernails). On wind instruments, a scoop is a glissando ascending to the onset of a note achieved entirely with the embouchure. Portamento Prescriptive attempts to distinguish the glissando from the portamento by limiting the former to the filling in of discrete intermediate pitches on instruments like the piano, harp, and fretted stringed instruments have r ...

Audio Crossover
Audio crossovers are a type of electronic filter circuitry that splits an audio signal into two or more frequency ranges, so that the signals can be sent to loudspeaker drivers that are designed to operate within different frequency ranges. The crossover filters can be either active or passive. They are often described as ''two-way'' or ''three-way'', which indicate, respectively, that the crossover splits a given signal into two frequency ranges or three frequency ranges. Crossovers are used in loudspeaker cabinets, power amplifiers in consumer electronics ( hi-fi, home cinema sound and car audio) and pro audio and musical instrument amplifier products. For the latter two markets, crossovers are used in bass amplifiers, keyboard amplifiers, bass and keyboard speaker enclosures and sound reinforcement system equipment (PA speakers, monitor speakers, subwoofer systems, etc.). Crossovers are used because most individual loudspeaker drivers are incapable of covering the en ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Soundtrack
A soundtrack is recorded music accompanying and synchronised to the images of a motion picture, drama, book, television program, radio program, or video game; a commercially released soundtrack album of music as featured in the soundtrack of a film, video, or television presentation; or the physical area of a film that contains the synchronised recorded sound. In movie industry terminology usage, a sound track is an audio recording created or used in film production or post-production. Initially, the dialogue, sound effects, and music in a film each has its own separate track (''dialogue track'', ''sound effects track'', and '' music track''), and these are mixed together to make what is called the ''composite track,'' which is heard in the film. A '' dubbing track'' is often later created when films are dubbed into another language. This is also known as an M&E (music and effects) track. M&E tracks contain all sound elements minus dialogue, which is then supplied by the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
