Record Restoration
Record restoration, a particular kind of audio restoration, is the process of converting the analog signal stored on gramophone records (either 78 rpm shellac, or 45 and 33⅓ rpm vinyl) into digital audio files that can then be edited with computer software and eventually stored on a hard-drive, recorded to digital tape, or burned to a CD or DVD. The process may be divided into several separate steps performed in the following order: # Cleaning the record, to prevent unwanted audio artifacts from being introduced in the capture that will necessitate correction in the digital domain (e.g. transient surface noise caused by dirt), and to prevent unnecessary wear and damage to the stylus used in playback. # Transcription of the record to another format on another medium (generally a digital format such as a wav file on a computer); # Processing the raw sound file with software in order to remove transient noise resulting from record surface damage ( clicks, pops, and crackle caused ...

Audio Restoration
Audio restoration is the process of removing imperfections (such as hiss, impulse noise, crackle, wow and flutter, background noise, and mains hum) from sound recordings. Audio restoration can be performed directly on the recording medium (for example, washing a gramophone record with a cleansing solution), or on a digital representation of the recording using a computer (such as an AIFF or WAV file). Record restoration is a particular form of audio restoration that seeks to repair the sound of damaged gramophone records. Modern audio restoration techniques are usually performed by digitizing an audio source from analog media, such as lacquer recordings, optical sources and magnetic tape. Once in the digital realm, recordings can be restored and cleaned up using dedicated, standalone digital processing units such as declickers, decracklers, dehissers and dialogue noise suppressors, or using digital audio workstations (DAWs). DAWs can perform various automated techniques to r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diamond Cut Audio Restoration Tools
Diamond Cut Audio Restoration Tools (also known as DC-Art and Diamond Cut Audio Lab) is a set of digital audio editor tools from Diamond Cut Productions used for audio restoration, record restoration, sound restoration of gramophone records and other audio containing media. Origins Diamond Cut Audio Restoration Tools (DC-Art) was originally a private venture by R&D engineer Craig Maier and software engineer Rick Carlson. Developed in the early 1990s, the original concept was conceived in an attempt to preserve the extensive Edison Lateral collection of test pressing recordings held at the Edison National Historic Site in West Orange, New Jersey. DC-Art was developed so that the many test pressings could be transferred to digital tape for preservation and archival purposes. The total number of songs which were recorded with the original software numbered over 1200 in anywhere from two to five takes and included many recordings that had not been played since the late 1920s.

Thomas Edison National Historical Park
Thomas Edison National Historical Park preserves Thomas Edison's laboratory and residence, ''Glenmont'', in West Orange, New Jersey, United States. These were designed, in 1887, by architect Henry Hudson Holly. The Edison laboratories operated for more than 40 years. Out of the West Orange laboratories came the motion picture camera, improved phonographs, sound recordings, silent and sound movies and the nickel-iron alkaline electric storage battery. Properties The park comprises two properties in West Orange: the second Edison Laboratories complex and Edison's home in Llewellyn Park about to the west at . The laboratory complex comprises the industrial facility built by Edison in 1887 to research and develop his inventions. The complex includes more than a dozen buildings that supported Edison's research into electricity, photography, motion pictures, chemistry, metallurgy and other disciplines. A private library was attached to the main laboratory building. Specialty heav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Edison Records
Edison Records was one of the early record labels that pioneered sound recording and reproduction, and was an important player in the early recording industry. The first phonograph cylinders were manufactured in 1888, followed by Edison's foundation of the Edison Phonograph Company in the same year. The recorded wax cylinders, later replaced by Blue Amberol cylinders, and vertical-cut Diamond Discs, were manufactured by Edison's National Phonograph Company from 1896 on, reorganized as Thomas A. Edison, Inc. in 1911. Until 1910 the recordings did not carry the names of the artists. The company began to lag behind its rivals in the 1920s, both technically and in the popularity of its artists, and halted production of recordings in 1929. Before commercial mass-produced records Thomas A. Edison invented the phonograph, the first device for recording and playing back sound, in 1877. After patenting the invention and benefiting from the publicity and acclaim it received, Edison and h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Software Engineering
Software engineering is a systematic engineering approach to software development. A software engineer is a person who applies the principles of software engineering to design, develop, maintain, test, and evaluate computer software. The term '' programmer'' is sometimes used as a synonym, but may also lack connotations of engineering education or skills. Engineering techniques are used to inform the software development process which involves the definition, implementation, assessment, measurement, management, change, and improvement of the software life cycle process itself. It heavily uses software configuration management which is about systematically controlling changes to the configuration, and maintaining the integrity and traceability of the configuration and code throughout the system life cycle. Modern processes use software versioning. History Beginning in the 1960s, software engineering was seen as its own type of engineering. Additionally, the development of soft ...

Archival
An archive is an accumulation of historical records or materials – in any medium – or the physical facility in which they are located. Archives contain primary source documents that have accumulated over the course of an individual or organization's lifetime, and are kept to show the function of that person or organization. Professional archivists and historians generally understand archives to be records that have been naturally and necessarily generated as a product of regular legal, commercial, administrative, or social activities. They have been metaphorically defined as "the secretions of an organism", and are distinguished from documents that have been consciously written or created to communicate a particular message to posterity. In general, archives consist of records that have been selected for permanent or long-term preservation on grounds of their enduring cultural, historical, or evidentiary value. Archival records are normally unpublished and almost alway ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vacuum Tube
A vacuum tube, electron tube, valve (British usage), or tube (North America), is a device that controls electric current flow in a high vacuum between electrodes to which an electric voltage, potential difference has been applied. The type known as a thermionic tube or thermionic valve utilizes thermionic emission of electrons from a hot cathode for fundamental electronic functions such as signal amplifier, amplification and current rectifier, rectification. Non-thermionic types such as a vacuum phototube, however, achieve electron emission through the photoelectric effect, and are used for such purposes as the detection of light intensities. In both types, the electrons are accelerated from the cathode to the anode by the electric field in the tube. The simplest vacuum tube, the diode (i.e. Fleming valve), invented in 1904 by John Ambrose Fleming, contains only a heated electron-emitting cathode and an anode. Electrons can only flow in one direction through the device—fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phonograph
A phonograph, in its later forms also called a gramophone (as a trademark since 1887, as a generic name in the UK since 1910) or since the 1940s called a record player, or more recently a turntable, is a device for the mechanical and analogue recording and reproduction of sound. The sound vibration waveforms are recorded as corresponding physical deviations of a spiral groove engraved, etched, incised, or impressed into the surface of a rotating cylinder or disc, called a "record". To recreate the sound, the surface is similarly rotated while a playback stylus traces the groove and is therefore vibrated by it, very faintly reproducing the recorded sound. In early acoustic phonographs, the stylus vibrated a diaphragm which produced sound waves which were coupled to the open air through a flaring horn, or directly to the listener's ears through stethoscope-type earphones. The phonograph was invented in 1877 by Thomas Edison. Alexander Graham Bell's Volta Laboratory made s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Signal Processing
Digital signal processing (DSP) is the use of digital processing, such as by computers or more specialized digital signal processors, to perform a wide variety of signal processing operations. The digital signals processed in this manner are a sequence of numbers that represent samples of a continuous variable in a domain such as time, space, or frequency. In digital electronics, a digital signal is represented as a pulse train, which is typically generated by the switching of a transistor. Digital signal processing and analog signal processing are subfields of signal processing. DSP applications include audio and speech processing, sonar, radar and other sensor array processing, spectral density estimation, statistical signal processing, digital image processing, data compression, video coding, audio coding, image compression, signal processing for telecommunications, control systems, biomedical engineering, and seismology, among others. DSP can involve linear or nonli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
