Eltro Information Rate Changer
The Eltro information rate changer was an analog recording tool used to modulate pitch without changing speed and vice versa. Patents for the device date back to the 1920s. The Eltro was the first technology capable of changing audio pitch (frequency) and speed (time) independently from one another. The technology was developed in Germany by engineer Anton Marian Springer (1909-1964).https://soundandscience.de/contributor-essays/anton-springer-and-time-and-pitch-regulator The Eltro was an accessory device that worked in conjunction with a reel-to-reel tape recorder. Recorders compatible with the Eltro became widely available in the 1950s. The device was first publicly demonstrated in 1953. By the mid 1960s the Eltro was a relatively common piece of equipment in many recording studios. The Eltro was often used to adjust the timing of radio commercials to fit them into 30 second or 60 second slots. By using the Eltro a recording engineer could have greater control over the exact len ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Analog Recording
Analog recording is a technique used for the recording of analog signals which, among many possibilities, allows analog audio for later playback. Analog audio recording began with mechanical systems such as the phonautograph and phonograph. Later, electronic techniques such as wire and tape recording were developed. Analog recording methods store analog signals directly in or on the media. The signal may be stored as a physical texture on a phonograph record, or a fluctuation in the field strength of a magnetic recording. Analog transmission methods use analog signals to distribute audio content. These are in contrast to digital audio where an analog signal is sampled and quantized to produce a digital signal which is represented, stored and transmitted as discrete numbers.

Douglas Rain
Douglas James Rain (March 13, 1928 – November 11, 2018) was a Canadian actor and narrator. Although primarily a stage actor, he is perhaps best known for his voicing of the HAL 9000 computer in the film '' 2001: A Space Odyssey'' (1968) and its sequel '' 2010: The Year We Make Contact'' (1984). Early life Rain was born in Winnipeg, Manitoba, the son of Mary, a nurse, and James Rain, a rail yard switchman, both from Glasgow, Scotland. Career Rain graduated with a B.A. from the University of Manitoba in 1950, then studied acting at the Banff School of Fine Arts in Banff, Alberta and the Bristol Old Vic Theatre School in Bristol, England. He was a founding member of the Stratford Festival of Canada in 1953 and was associated with it as an actor until 1998. He performed a wide variety of theatrical roles, such as a production of ''Henry V'' staged in Stratford, Ontario, that was adapted for television in 1966. In 1972, he was nominated for the Tony Award for Best Supporting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Audio Workstation
A digital audio workstation (DAW) is an electronic device or application software used for Sound recording and reproduction, recording, editing and producing audio files. DAWs come in a wide variety of configurations from a single software program on a laptop, to an integrated stand-alone unit, all the way to a highly complex configuration of numerous components controlled by a central computer. Regardless of configuration, modern DAWs have a central interface that allows the user to alter and mix multiple recordings and tracks into a final produced piece. DAWs are used for producing and recording music, songs, human speech, speech, Radio broadcasting, radio, television, soundtracks, podcasts, sound effects and nearly any other situation where complex recorded audio is needed. Hardware Early attempts at digital audio workstations in the 1970s and 1980s faced limitations such as the high price of storage, and the vastly slower processing and disk speeds of the time. In 1978, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Software
Software is a set of computer programs and associated documentation and data. This is in contrast to hardware, from which the system is built and which actually performs the work. At the lowest programming level, executable code consists of machine language instructions supported by an individual processor—typically a central processing unit (CPU) or a graphics processing unit (GPU). Machine language consists of groups of binary values signifying processor instructions that change the state of the computer from its preceding state. For example, an instruction may change the value stored in a particular storage location in the computer—an effect that is not directly observable to the user. An instruction may also invoke one of many input or output operations, for example displaying some text on a computer screen; causing state changes which should be visible to the user. The processor executes the instructions in the order they are provided, unless it is instructed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Recording
In digital recording, an audio or video signal is converted into a stream of discrete numbers representing the changes over time in air pressure for audio, or chroma and luminance values for video. This number stream is saved to a storage device. To play back a digital recording, the numbers are retrieved and converted back into their original analog audio or video forms so that they can be heard or seen. In a properly matched analog-to-digital converter (ADC) and digital-to-analog converter (DAC) pair the analog signal is accurately reconstructed per the constraints of the Nyquist–Shannon sampling theorem dependent on the sampling rate and quantization error dependent on the audio or video bit depth. Because the signal is stored digitally, assuming proper error detection and correction, the recording is not degraded by copying, storage or interference.

Stereo
Stereophonic sound, or more commonly stereo, is a method of sound reproduction that recreates a multi-directional, 3-dimensional audible perspective. This is usually achieved by using two independent audio channels through a configuration of two loudspeaker A loudspeaker (commonly referred to as a speaker or speaker driver) is an electroacoustic transducer that converts an electrical audio signal into a corresponding sound. A ''speaker system'', also often simply referred to as a "speaker" or " ...s (or stereo headphones) in such a way as to create the impression of sound heard from various directions, as in natural hearing. Because the multi-dimensional perspective is the crucial aspect, the term ''stereophonic'' also applies to systems with more than two channels or speakers such as quadraphonic and surround sound. Binaural recording, Binaural sound systems are also ''stereophonic''. Stereo sound has been in common use since the 1970s in entertainment media such ...

Monaural
Monaural or monophonic sound reproduction (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 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 mixed d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HAL 9000
HAL 9000 is a fictional artificial intelligence character and the main antagonist in Arthur C. Clarke's ''Space Odyssey'' series. First appearing in the 1968 film '' 2001: A Space Odyssey'', HAL ( Heuristically programmed ALgorithmic computer) is a sentient artificial general intelligence computer that controls the systems of the '' Discovery One'' spacecraft and interacts with the ship's astronaut crew. While part of HAL's hardware is shown toward the end of the film, he is mostly depicted as a camera lens containing a red or yellow dot, with such units located throughout the ship. HAL 9000 is voiced by Douglas Rain in the two feature film adaptations of the ''Space Odyssey'' series. HAL speaks in a soft, calm voice and a conversational manner, in contrast to the crewmen, David Bowman and Frank Poole. In the film, HAL became operational on 12 January 1992 at the HAL Laboratories in Urbana, Illinois as production number 3. The activation year was 1991 in earlier screenpl ...

A Space Odyssey (film)
''2001: A Space Odyssey'' is a 1968 science fiction novel written by Arthur C. Clarke and the 1968 film directed by Stanley Kubrick. It is a part of Clarke's ''Space Odyssey'' series, the first of four novels and two films. Both the novel and the film are partially based on Clarke's 1948 short story " The Sentinel", an entry in a BBC short story competition, and "Encounter in the Dawn", published in 1953 in the magazine ''Amazing Stories''. Resources After deciding on Clarke's 1948 short story "The Sentinel" as the starting point, and with the themes of man's relationship with the universe in mind, Clarke sold Kubrick five more of his stories to use as background materials for the film. These included "Breaking Strain", "Out of the Cradle, Endlessly Orbiting...", "Who's There?", "Into the Comet", and "Before Eden". Additionally, important elements from two more Clarke stories, "Encounter in the Dawn" and (to a somewhat lesser extent) "Rescue Party", made their way into ...

Pitch (music)
Pitch is a perceptual property of sounds that allows their ordering on a frequency-related scale, or more commonly, pitch is the quality that makes it possible to judge sounds as "higher" and "lower" in the sense associated with musical melodies. Pitch is a major auditory attribute of musical tones, along with duration, loudness, and timbre. Pitch may be quantified as a frequency, but pitch is not a purely objective physical property; it is a subjective psychoacoustical attribute of sound. Historically, the study of pitch and pitch perception has been a central problem in psychoacoustics, and has been instrumental in forming and testing theories of sound representation, processing, and perception in the auditory system. Perception Pitch and frequency Pitch is an auditory sensation in which a listener assigns musical tones to relative positions on a musical scale based primarily on their perception of the frequency of vibration. Pitch is closely related to frequency, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
She's Goin' Bald
"She's Goin' Bald" is a song by American rock band the Beach Boys form their 1967 album ''Smiley Smile''. It was written by Brian Wilson, Mike Love, and Van Dyke Parks. Like many of the songs on that album, it has roots in the abandoned ''Smile'' album, as the short song "He Gives Speeches". Both compositions follow the "How Dry I Am" progression. Background "He Gives Speeches" was recorded for the abandoned ''Smile''. After the collapse of ''Smile'', "He Gives Speeches" was left unreleased. The song was later rewritten and rerecorded for ''Smiley Smile'' as "She's Goin' Bald" with new lyrics by Mike Love. In 1995, Brian Wilson said that it was only a coincidence that Love himself "was on his way to goin' bald then," and that the group did the song without being aware that he might have thought it was about him. Brian then called it "one of the funnier songs he Beach Boysever done, very current for its time." On Love's contribution to the song, Bruce Johnston commented, "You wa ...

The Beach Boys
The Beach Boys are an American Rock music, rock band that formed in Hawthorne, California, in 1961. The group's original lineup consisted of brothers Brian Wilson, Brian, Dennis Wilson, Dennis, and Carl Wilson, their cousin Mike Love, and friend Al Jardine. Distinguished by their vocal harmony, vocal harmonies, adolescent-themed lyrics, and musical ingenuity, they are one of the most influential acts of the rock era. They drew on the music of traditional pop, older pop vocal groups, 1950s rock and roll, and black R&B to create their unique sound. Under Brian's direction, they often incorporated classical music, classical or jazz elements and Recording studio as an instrument, unconventional recording techniques in innovative ways. The Beach Boys began as a garage band, managed by the Wilsons' father Murry Wilson, Murry, with Brian serving as composer, arranger, producer, and ''de facto'' leader. In 1963, they enjoyed their first national hit with "Surfin' U.S.A.", beginning a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
