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] |

Creative Technology Limited
Creative Technology Ltd. is a Singaporean multinational technology company headquartered with overseas offices in Shanghai, Tokyo, Dublin, and Silicon Valley (where in the US it is known as Creative Labs). The principal activities of the company and its subsidiaries consist of the design, manufacture and distribution of digitized sound and video boards, computers and related multimedia and personal digital entertainment products. It also partners with mainboard manufacturers and laptop brands to embed its Sound Blaster technology on their products. 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 computer. Later, Creative spent $500,000 developing the Cubic CT, an IBM-compatible PC adapted for the Chinese language and featuring multimedia fe ...

Operational Amplifier
An operational amplifier (often op amp or opamp) is a DC-coupled high-gain electronic voltage amplifier with a differential input and, usually, a single-ended output. In this configuration, an op amp produces an output potential (relative to circuit ground) that is typically 100,000 times larger than the potential difference between its input terminals. The operational amplifier traces its origin and name to analog computers, where they were used to perform mathematical operations in linear, non-linear, and frequency-dependent circuits. The popularity of the op amp as a building block in analog circuits is due to its versatility. By using negative feedback, the characteristics of an op-amp circuit, its gain, input and output impedance, bandwidth etc. are determined by external components and have little dependence on temperature coefficients or engineering tolerance in the op amp itself. Op amps are used widely in electronic devices today, including a vast array of consumer, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AptX
aptX (''apt'' stands for ''audio processing technology'') is a family of proprietary audio codec An audio codec is a device or computer program capable of encoding or decoding a digital data stream (a codec) that encodes or decodes audio. In software, an audio codec is a computer program implementing an algorithm that compresses and decompres ... compression algorithms owned by Qualcomm, with a heavy emphasis on wireless audio applications. History The original aptX 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 Adaptive DPCM, ADPCM principles without psychoacoustic auditory masking techniques. aptX audio coding was first introduced to the commercial market as a semiconductor product, a custom programmed Digital signal processor, DSP integrated circuit with part name APTX100ED, which was initially adopted ...

Dolby Digital Live
Dolby Digital, originally synonymous with Dolby AC-3, is the name for what has now become a family of audio compression (data), audio compression technologies developed by Dolby Laboratories. Formerly named Dolby Stereo Digital until 1995 in film, 1995, the audio compression is lossy compression, lossy (except for Dolby TrueHD), based on the modified discrete cosine transform (MDCT) algorithm. The first use of Dolby Digital was to provide digital sound in cinemas from 35 mm film prints; today, it is also used for applications such as TV broadcast, radio broadcast via satellite, digital video streaming, DVDs, Blu-ray discs and game consoles. The main basis of the Dolby AC-3 multi-channel audio coding standard is the modified discrete cosine transform (MDCT), a lossy compression, lossy audio compression (data), audio compression algorithm. It is a modification of the discrete cosine transform (DCT) algorithm, which was first proposed by N. Ahmed, Nasir Ahmed in 1972 and was orig ...

DTS Connect
DTS, Inc. (originally Digital Theater Systems) is an American company that 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. The DTS brand was acquired by Tessera Holding Corporation in December 2016, then Tessera was renamed to Xperi Corporation. 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 of the Third Kind'' mixed in DTS. Spielberg then selected DTS sound for his next film, ''Jur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Space
Space is the boundless three-dimensional extent in which objects and events have relative position and direction. In classical physics, physical space is often conceived in three linear dimensions, although 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. Debates concerning the nature, essence and the mode of existence of space date back to antiquity; namely, to treatises like the ''Timaeus'' of Plato, or Socrates in his reflections on what the Greeks called ''khôra'' (i.e. "space"), or in the ''Physics'' of Aristotle (Book IV, Delta) in the definition of ''topos'' (i.e. place), or in the later "geometrical conception of place" as "spac ...
