Sound Blaster X7
The Sound Blaster X7 is a USB audio device that can work without a computer. It was announced on 3 September 2014. It supports Microsoft Windows and Mac OS X computers but requires a power supply to work. The Sound Blaster X7 has the SB-Axx1 sound chip built-in. Android and iOS devices can change SBX Pro Studio audio settings with the Sound Blaster X7 Control app. Settings are also saved into the X7 after changes are made with the Sound Blaster X7 Control app. It is Creative Technology Limited's first USB audio device that supports stereo passive speakers. Like the Sound Blaster ZxR, it allows its op-amps to be swapped. The device does not have an encoder but can decode Dolby Digital 5.1 signals. The Sound Blaster X7’s Bluetooth feature is only for receiving audio signals from Bluetooth devices, it can’t be used for transmitting audio signals to Bluetooth speakers and headphones. The Bluetooth codecs supported by the X7 are AAC, SBC, aptX and aptX Low Latency. Differences ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Creative Technology Limited
Creative Technology Ltd., or Creative Labs Pte Ltd., is a Singaporean multinational electronics company mainly dealing with audio technologies and products such as speakers, headphones, sound cards and other digital media. Founded by Sim Wong Hoo, Creative was highly influential in the advancement of PC audio in the 1990s following the introduction of its Sound Blaster card and technologies; the company continues to develop Sound Blaster products including embedding them within partnered mainboard manufacturers and laptops. The company also has overseas offices in Shanghai, Tokyo, Dublin and the Silicon Valley. Creative Technology has been listed on the Singapore Exchange (SGX) since 1994. History 1981–1996 Creative Technology was founded in 1981 by childhood friends and Ngee Ann Polytechnic schoolmates Sim Wong Hoo and Ng Kai Wa. Originally a computer repair shop in Pearl's Centre in Chinatown, the company eventually developed an add-on memory board for the Apple II c ...

Operational Amplifier
An operational amplifier (often op amp or opamp) is a direct coupling, DC-coupled Electronic component, electronic voltage amplifier with a differential input, a (usually) Single-ended signaling, single-ended output, and an extremely high gain (electronics), gain. Its name comes from its original use of performing mathematical operations in analog computers. By using negative feedback, an Op amp circuits, op amp circuit's characteristics (e.g. its gain, input and output impedance, bandwidth (signal processing), bandwidth, and functionality) can be determined by external components and have little dependence on temperature coefficients or engineering tolerance in the op amp itself. This flexibility has made the op amp a popular building block in analog circuits. Today, op amps are used widely in consumer, industrial, and scientific electronics. Many standard integrated circuit op amps cost only a few cents; however, some integrated or hybrid operational amplifiers with special p ...

AptX
aptX (''apt'' stands for ''audio processing technology'') is a family of proprietary audio codec compression algorithms owned by Qualcomm, with a heavy emphasis on wireless audio applications. History The original compression algorithm was developed in the 1980s by Dr. Stephen Smyth as part of his Ph.D. research at Queen's University Belfast School of Electronics, Electrical Engineering and Computer Science. Its design is based on time domain ADPCM principles without psychoacoustic auditory masking techniques. The algorithm was then commercialized under the name aptX and first introduced to the commercial market as a semiconductor product, a custom programmed DSP integrated circuit with part name APTX100ED, which was initially adopted by broadcast automation equipment manufacturers who required a means to store CD-quality audio on a computer hard disk drive for automatic playout during a radio show, for example, hence replacing the task of the disc jockey. The company w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Dolby Digital Live
Dolby Digital, originally synonymous with #Dolby AC-3, Dolby AC-3 (see below), is the name for a family of audio compression (data), audio compression technologies developed by Dolby Laboratories. Called Dolby Stereo Digital until 1995 in film, 1995, it is lossy compression (except for Dolby TrueHD). The first use of Dolby Digital was to provide digital sound in cinemas from 35 mm film prints. It has since also been used for TV broadcast, radio broadcast via satellite, digital video streaming, DVDs, Blu-ray discs and game consoles. Dolby AC-3 was the original version of the Dolby Digital codec. The basis of the Dolby AC-3 multi-channel audio coding standard is the modified discrete cosine transform (MDCT), a lossy audio compression (data), audio compression algorithm. It is a modification of the discrete cosine transform (DCT) algorithm, which was proposed by N. Ahmed, Nasir Ahmed in 1972 for image compression. The DCT was adapted into the MDCT by J.P. Princen, A.W. Johnson ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
DTS Connect
DTS, Inc. (originally Digital Theater Systems) is an American company. DTS company makes multichannel audio technologies for film and video. Based in Calabasas, California, the company introduced its DTS technology in 1993 as a competitor to Dolby Laboratories, incorporating DTS in the film ''Jurassic Park'' (1993). The DTS product is used in surround sound formats for both commercial/theatrical and consumer-grade applications. It was known as The Digital Experience until 1995. DTS licenses its technologies to consumer electronics manufacturers. DTS, Inc. was acquired by Tessera Technologies Inc. in December 2016 and combined under the newly created Tessera Holding Corporation. The combined company was renamed to Xperi Corporation in February 2017. History DTS was founded by Terry Beard, an audio engineer and Caltech graduate. Beard, speaking to a friend of a friend, was able to get in touch with Steven Spielberg to audition a remastering of Spielberg's film ''Close Encounters ...

Space
Space is a three-dimensional continuum containing positions and directions. In classical physics, physical space is often conceived in three linear dimensions. Modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as '' spacetime''. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework. In the 19th and 20th centuries mathematicians began to examine geometries that are non-Euclidean, in which space is conceived as '' curved'', rather than '' flat'', as in the Euclidean space. According to Albert Einstein's theory of general relativity, space around gravitational fields deviates from Euclidean space. Experimental tests of general relativity have confirmed that non-Euclidean geometries provide a bet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
