Information: - Professional audio, occasionally abbreviated as pro audio, refers to both an activity and a type of high quality audio equipment. Typically it encompasses sound recording, sound reinforcement system setup and mixing, and studio music production by trained sound engineers, audio engineers and audio technicians who work in live event support, using audio mixers or sound reinforcement systems. In contrast, consumer audio equipment is usually confined to the reproduction of sound in a private home on a home stereo or home cinema system. - Taipei Exchange (), formerly the Gre Tai Securities Market (GTSM), is a foundation which organized for serving the over-the-counter (OTC) market and bond trading of Taiwan. It was formally found on November 1, 1994. The initial fund of the foundation was donated by the Taiwan Stock Exchange, Taiwan Securities Association, and Taiwan Depository & Clearing. It headquarters is at Zhongzheng District of Taipei City. In February 2015, the Gre Tai securities market changed its name to Taipei Exchange. - Phonic Corporation is a Taiwanese public company that manufactures and sells professional audio equipment , including mixing consoles , loudspeakers , studio monitors , and digital recording devices . Established in 1977 , Phonic provided original equipment manufacturing to various audio companies during the 1980s . Shares of Phonic Corporation are publicly traded on the Gre Tai Securities Market . - The Taiwan Stock Exchange Corporation (TWSE) is a financial institution, located in Taipei 101, in Taipei, Taiwan. The TWSE was established in 1961 and began operating as a stock exchange on 9 February 1962. It is regulated by the Financial Supervisory Commission. - A loudspeaker (or loud-speaker or speaker) is an electroacoustic transducer; which converts an electrical audio signal into a corresponding sound. The most widely used type of speaker in the 2010s is the dynamic speaker, invented in 1925 by Edward W. Kellogg and Chester W. Rice. The dynamic speaker operates on the same basic principle as a dynamic microphone, but in reverse, to produce sound from an electrical signal. When an alternating current electrical audio signal is applied to its voice coil, a coil of wire suspended in a circular gap between the poles of a permanent magnet, the coil is forced to move rapidly back and forth due to Faraday's law of induction, which causes a diaphragm (usually conically shaped) attached to the coil to move back and forth, pushing on the air to create sound waves. Besides this most common method, there are several alternative technologies that can be used to convert an electrical signal into sound. The sound source (e.g., a sound recording or a microphone) must be amplified or strengthened with an audio power amplifier before the signal is sent to the speaker. - In digital recording, audio signals picked up by a microphone or other transducer or video signals picked up by a camera or similar device are converted into a stream of discrete numbers, representing the changes over time in air pressure for audio, and chroma and luminance values for video, then recorded to a storage device. To play back a digital sound recording, the numbers are retrieved and converted back into their original analog waveforms so that they can be heard through a loudspeaker. To play back a digital video recording, the numbers are retrieved and converted back into their original analog waveforms so that they can be viewed on a video monitor, television or other display. - Taiwan, officially the Republic of China (ROC), is a state in East Asia. Neighbors include China (officially the People's Republic of China, abbreviated as PRC) to the west, Japan to the northeast, and the Philippines to the south. Taiwan is the most populous state that is not a member of the United Nations, and the one with the largest economy. - Home cinema, also called home theater or home theatre, refers to home entertainment audio-visual systems that seek to reproduce a movie theater experience and mood using consumer electronics-grade video and audio equipment that is set up in a room or backyard of a private home. In the 1980s, home cinemas typically consisted of a movie pre-recorded on a LaserDisc or VHS tape; a LaserDisc or VHS player; and a heavy, bulky large-screen cathode ray tube TV set. In the 2000s, technological innovations in sound systems, video player equipment and TV screens and video projectors have changed the equipment used in home theatre set-ups and enabled home users to experience a higher-resolution screen image, improved sound quality and components that offer users more options (e.g., many of the more expensive Blu-ray players in 2016 can also "stream" movies and TV shows over the Internet using subscription services such as Netflix). The development of Internet-based subscription services means that 2016-era home theatre users do not have to commute to a video rental store as was common in the 1980s and 1990s (nevertheless, some movie enthusiasts buy DVD or Blu-ray discs of their favourite content). - Video is an electronic medium for the recording, copying, playback, broadcasting, and display of moving visual media. - Zhongzheng District is a district in Taipei, Taiwan. It is the home of most of the national government buildings of the Republic of China, this includes the Presidential Office, the Executive Yuan, the Control Yuan, the Legislative Yuan, the Judicial Yuan and various government ministries. This district is named after Generalissimo and the late President of the Republic of China Chiang Kai-shek.
