Fantasound Tracks
Fantasound was a sound reproduction system developed by engineers of The Walt Disney Company, Walt Disney studios and RCA for Walt Disney's animated film ''Fantasia (1940 film), Fantasia'', the first commercial film released in stereo. Origins Walt Disney's cartoon character Mickey Mouse entered a decline in popularity in the mid-1930s. Disney devised a comeback appearance for Mickey in 1936 with ''The Sorcerer's Apprentice'', a more elaborate edition of the animated ''Silly Symphonies'' series set to the music of ''The Sorcerer's Apprentice (Dukas), The Sorcerer's Apprentice'' by Paul Dukas. Disney met conductor Leopold Stokowski in late 1937 at Chasen's, a noted Hollywood, Los Angeles, Hollywood restaurant, and Stokowski agreed to conduct the piece at no cost. Stokowski was an enthusiast for new and improved methods of sound reproduction and had already participated in experimental stereophonic sound recordings in 1931 and 1932, and a live, long-distance demonstration of multi-ch ...

Sound Reproduction
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. 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 varying magnetic field by an electromagnet, which makes a representation of the sound as magnetized areas on a plastic tape with a magnetic coating on it. Analog sound reproduction is the reverse process, with a larger loudspeaker diaphragm c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monaural
Monaural sound or monophonic sound (often shortened to mono) is sound intended to be heard as if it were emanating from one position. This contrasts with stereophonic sound or ''stereo'', which uses two separate audio channels to reproduce sound from two microphones on the right and left side, which is reproduced with two separate loudspeakers to give a sense of the direction of sound sources. In mono, only one loudspeaker is necessary, but, when played through multiple loudspeakers or headphones, identical audio signals are fed to each speaker, resulting in the perception of one-channel sound "imaging" in one sonic space between the speakers (provided that the speakers are set up in a proper symmetrical critical-listening placement). Monaural recordings, like stereo ones, typically use multiple microphones fed into multiple channels on a recording console, but each channel is " panned" to the center. In the final stage, the various center-panned signal paths are usually mix ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burbank, California
Burbank is a city in the southeastern end of the San Fernando Valley in Los Angeles County, California, United States. Located northwest of downtown Los Angeles, Burbank had a Census-estimated population of 102,755 as of 2023. The city was named after David Burbank, who established a sheep ranch there in 1867. Burbank consists of two distinct areas: a downtown/foothill section, in the foothills of the Verdugo Mountains, and the flatland section. Numerous media and entertainment companies are headquartered or have significant production facilities in Burbank—often called the "Media Capital of the World" and only a few miles northeast of Hollywood—including Warner Bros. Entertainment, the Walt Disney Company, Nickelodeon Animation Studio, The Burbank Studios, Cartoon Network Studios with the West Coast branch of Cartoon Network, and Insomniac Games. Universal plays a key role in attractions and entertainment in Burbank, with its theme park Universal Studios Holl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Walt Disney Studios (Burbank)
The Walt Disney Studios, located in Burbank, California, United States, serves as the corporate headquarters for the Walt Disney Company. The 51-acre (20.6 ha) Film studio, studio lot also contains several sound stages, a backlot, and other filmmaking production facilities for Walt Disney Studios (division), Walt Disney Studios's motion picture production.

Horn Loudspeaker
A horn loudspeaker is a loudspeaker or loudspeaker element which uses an horn (acoustic), acoustic horn to increase the overall efficiency of the driving element(s). A common form ''(right)'' consists of a compression driver which produces sound waves with a small metal diaphragm vibrated by an electromagnet, attached to a horn, a flaring duct to conduct the sound waves to the open air. Another type is a woofer driver mounted in a loudspeaker enclosure which is divided by internal partitions to form a zigzag flaring duct which functions as a horn; this type is called a ''folded horn'' speaker. The horn serves to improve the coupling efficiency between the speaker driver and the air. The horn can be thought of as an "acoustic transformer" that provides impedance matching between the relatively density, dense diaphragm material and the less-dense air. The result is greater acoustic output power from a given driver. The narrow part of the horn next to the driver is called the "throat ...

Oscilloscopes
An oscilloscope (formerly known as an oscillograph, informally scope or O-scope) is a type of electronic test instrument that graphically displays varying voltages of one or more signals as a function of time. Their main purpose is capturing information on electrical signals for debugging, analysis, or characterization. The displayed waveform can then be analyzed for properties such as amplitude, frequency, rise time, time interval, distortion, and others. Originally, calculation of these values required manually measuring the waveform against the scales built into the screen of the instrument. Modern digital instruments may calculate and display these properties directly. Oscilloscopes are used in the sciences, engineering, biomedical, automotive and the telecommunications industry. General-purpose instruments are used for maintenance of electronic equipment and laboratory work. Special-purpose oscilloscopes may be used to analyze an automotive ignition system or to display t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cathode-ray Tube
A cathode-ray tube (CRT) is a vacuum tube containing one or more electron guns, which emit electron beams that are manipulated to display images on a phosphorescent screen. The images may represent electrical waveforms on an oscilloscope, a Film frame, frame of video on an Analog television, analog television set (TV), Digital imaging, digital raster graphics on a computer monitor, or other phenomena like radar targets. A CRT in a TV is commonly called a picture tube. CRTs have also been Williams tube, used as memory devices, in which case the screen is not intended to be visible to an observer. The term ''cathode ray'' was used to describe electron beams when they were first discovered, before it was understood that what was emitted from the cathode was a beam of electrons. In CRT TVs and computer monitors, the entire front area of the tube is scanned repeatedly and systematically in a fixed pattern called a raster scan, raster. In color devices, an image is produced by con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Click-track
A click track is a series of audio cues used to synchronize sound recordings, sometimes for synchronization to a moving image. The click track originated in early sound movies, where optical marks were made on the film to indicate precise timings for musical accompaniment. It can also serve a purpose similar to a metronome, as in the music industry, where it is often used during recording sessions and live performances.Gavin Harrison (August 2003).Creating Click Tracks For Drummers. Sound on Sound. Retrieved 8 June 2011. History The earliest known usage of "precise timing-aid" in movies may have been by Walt Disney’s team when recording music and sound effects for their early cartoons. Since cartoons at that time did not include dialogue, the jokes onscreen relied heavily on how precisely they were synchronized with the sound effects (e.g., one character hitting another with a frying pan is funniest when it occurs simultaneously with the "boing" sound effect). When the timin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nitrate Film
Nitrocellulose (also known as cellulose nitrate, flash paper, flash cotton, guncotton, pyroxylin and flash string, depending on form) is a highly flammable compound formed by nitration, nitrating cellulose through exposure to a mixture of nitric acid and sulfuric acid. One of its first major uses was as guncotton, a replacement for gunpowder as propellant in firearms. It was also used to replace gunpowder as a Explosive#By velocity, low-order explosive in mining and other applications. In the form of collodion, it was also a critical component in an early photographic emulsion, the use of which revolutionized photography in the 1860s. In the 20th century, it was adapted to automobile lacquer and adhesives. Production The process uses a mixture of nitric acid and sulfuric acid to convert cellulose into nitrocellulose. The quality of the cellulose is important. Hemicellulose, lignin, pentosans, and mineral salts give inferior nitrocelluloses. In organic chemistry, nitrocellulose ...

Sound-on-film
Sound-on-film is a class of sound film processes where the sound accompanying a picture is recorded on photographic film, usually, but not always, the same strip of film carrying the picture. Sound-on-film processes can either record an Analog signal, analog sound track or Digital data, digital sound track, and may record the signal either optical sound, optically or magnetism, magnetically. Earlier technologies were sound-on-disc, meaning the film's soundtrack would be on a separate phonograph record. History Sound on film can be dated back to the early 1880s, when Charles E. Fritts filed a patent claiming the idea. In 1923 a patent was filed by E. E. Ries, for a variable density soundtrack recording, which was submitted to the SMPE (now Society of Motion Picture and Television Engineers, SMPTE), which used the mercury vapor lamp as a modulating device to create a variable-density soundtrack. Later, Theodore Case, Case Laboratories and Lee De Forest#Phonofilm sound-on-film pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
