Audio signal

An audio signal is a representation of sound, typically as an electrical voltage. Audio signals have frequencies in the audio frequency range of roughly 20 to 20,000 Hz (the limits of human hearing). Audio signals may be synthesized directly, or may originate at a transducer such as a microphone, musical instrument pickup, phonograph cartridge, or tape head. Loudspeakers or headphones convert an electrical audio signal into sound. Digital representations of audio signals exist in a variety of formats.

An audio channel or audio track is an audio signal communications channel in a storage device, used in operations such as multi-track recording and sound reinforcement.

Signal flow

Signal flow is the path an audio signal will take from source (microphone) to the speaker or recording device. It is most frequently in a recording studio setting, where the signal flow is often very long and convoluted as the electric signal may pass through many sections of a large analog console, external audio equipment, and even different rooms.

Track 61 (New York City)

Track 61 is a private railway platform for the Metro-North Railroad in New York City, located beneath the Waldorf Astoria New York hotel and just outside Grand Central Terminal. The platform is part of the Grand Central Terminal complex.

First used by General John J. Pershing in 1938, and later by Franklin Delano Roosevelt in 1944, the platform was not originally intended to be used as a station, but its location made it ideal for unobtrusive access to the hotel. The track was also used for the exhibition of American Locomotive Company's new diesel locomotive in 1946; in 1948 Filene's and the New Haven Railroad staged a fashion show on the platform.As of May 1, 2014, it has been reported to still be in occasional use.

White and Black in chess

In chess, the player who moves first is referred to as "White" and the player who moves second is referred to as "Black". Similarly, the pieces that each conducts are called, respectively, "the white pieces" and "the black pieces". The pieces are often not literally white and black, but some other colors (usually a light color and a dark color, respectively). The 64 squares of the chessboard, which is colored in a checkered pattern, are likewise referred to as "white squares" or "light squares" on the one hand, and "black squares" or "dark squares" on the other. In most cases, the squares are not actually white and black, but a light color and a contrasting dark color. For example, the squares on plastic boards are often off-white ("buff") and green, while those on wood boards are often light brown and dark brown.

In old chess writings, the sides are often called Red and Black, because those were the two colors of ink then commonly available when hand-drawing or printing chess position diagrams.

Km (hieroglyph)

The Egyptian hieroglyph for "black" in Gardiner's sign list is numbered I6. Its phonetic value is km. The Wörterbuch der Aegyptischen Sprache-(Dictionary of the Egyptian Language) lists no less than 24 different terms of km indicating 'black' such as black stone, metal, wood, hair, eyes, and animals.

The most common explanation for the hieroglyph is under the Gardiner's Sign List, section I for "amphibious animals, reptiles, etc" is a crocodile skin with spines. Rossini and Schumann-Antelme propose that the crocodile skin hieroglyph actually shows claws coming out of the hide.

Besides 'black', the alternate use of the hieroglyph is for items terminating, coming-to-an-end, items of completion, hence a reference to charcoal, burning to its ending.

km.t

In the Demotic (Egyptian) text of the Rosetta Stone, the demotic for Egypt is 'Kmi' . There are three uses of the actual Kmi, but 7 others referenced as Kmi refer to iAt in the hieroglyphs. Other euphemistic references to Egypt in the Rosetta Stone include "Ta-Mer-t", which has the meaning of the 'full/fruitful/cultivated land', hr-tAwy, the 'lands of Horus', and tAwy, the "Two Lands."

Asterisk

An asterisk (*; from Late Latin asteriscus, from Ancient Greek ἀστερίσκος, asteriskos, "little star") is a typographical symbol or glyph. It is so called because it resembles a conventional image of a star. Computer scientists and mathematicians often vocalize it as star (as, for example, in the A* search algorithm or C*-algebra). In English, an asterisk is usually five-pointed in sans-serif typefaces, six-pointed in serif typefaces, and six- or eight-pointed when handwritten. It can be used as censorship. It is also used on the internet to correct one's spelling, in which case it appears after or before the corrected word.

The asterisk is derived from the need of the printers of family trees in feudal times for a symbol to indicate date of birth. The original shape was seven-armed, each arm like a teardrop shooting from the center.

In computer science, the asterisk is commonly used as a wildcard character, or to denote pointers, repetition, or multiplication.

Usage

Censorship

When toning down expletives, asterisks are often used to replace letters. For example, the word 'fuck' might become 'f*ck' or even '****'.
