November 220, 1920，American KDKA radio station for the first commercial broadcast in human history。But，When the historian of the news communication understands the technical devices such as radio stations as a mass media，Often ignored the technical nature of the media itself，Ignoring the material configuration and technical and cultural significance hidden behind the media。In other words，For humanities and sociology,，It may be not enough to understand that broadcasting only in the sense of social function，It also needs to be restored as a technical device，and ask: The sound can be recorded and transmitted by electromagnetic，What does it mean? When we ask this question，I will find that this problem is not only the problem of modern mass dissemination，Back to the source of science -ancient Greece。"Sound recorded" incident，It has special significance in ancient Greek culture。

　　Alphabet is the skill of the sound of ancient records。From the perspective of some classical scholars，The ancient Greek invented Greek alphabet，First of all, it is not because of the needs of economic and trade and law，Instead, it is directly related to the sound of reproduction。They want to invent a cultural skill that can store poetry rhyme，So vowels，The Greek alphabet that is most suitable for portraying Homer Epic Six Rhyme。Just as F. A. Kittler concluded: "We can't find the ancient Greeks about trade、Records of the government and law，and can only find wine with them、Women and Singing -Just like in "Odyssey"。”

Regardless of whether the above statement is credible，Alphabet as a general sound processing technology at that time，It undoubtedly had a profound impact on Western culture: it can not only record the sound of the mouth, but，And being applied to a unique mathematics -music note system。Invention in the letters in the letters hundreds of years later，The ancient Greeks began to use alpha fingling numbers 1，β refers to Digital 2 ... A independent mathematical system。THOMAS Heath (THOMAS Heath) commented in "A History of Greek Mathematics": Use letters to refer to digital deferred，It is the original of the Greeks。Ancient Greek mathematician Philolaus, PHILOLAUS, uses the number as a beat symbol，Magic of making music a math。This looks like，The ancient Greek people use the alphabet to use the medium of accurate depicting sound -just as all numbers can be expressed in a number，The sound is also among the mesh of the alphabet。

But，There is a sound that is a fish that is missing -Siren's singing，Among the mortals who have heard this song，Only Oduez claims to escape from a calamity，As for what I sang，Homer can only be described as "wonderful"。The sound of the illegal watch watch，It can not be understood until the era of the electromagnetic media。Time jump to March 2004，Kidler came to the place where the song of Siren was said -near Gallo Lungo Island。His team's technical analysis of sound and display，The sound of people's legend is actually a natural product: the sound from Gallo LUNGO Island hit the rock，and jump back and forth between two rocks，The result became the voice of charm。This conclusion，It also announced that the "Song of the Bet365 app download Banshee" is removed by modern technology devices。

Kidler's "research" that is commonly considered to be myth seems absurd，In fact, it reveals the unique significance of modern sound processing device: no sound can avoid the "gaze" of electronic media technology。The sound is no longer something that people hear，but the real signal in the physical sense; the song of Siren is not a mysterious voice，The frequency must be captured and portrayed by the sound measurement device。

Electromagnetic Stream — Signal replaced human voice -letters，means a new field of acoustics -opening in the field of signal。Ancient spectrometer follows the order of archives (Archival Order)，The sound of the signal is disorderly (anarchive)，Decoding of technical devices to become meaningful to humans。Cultural investigation of media and other media technology，Can't ignore it as the side of the technical device。Technology's own materiality and signal processing ability，Make it fundamentally distinguished from the letters of letters。

　　Honor and Broadcast

Alphabet、Bookmarking method to refer to the sound is destined to be futile，It is impossible to fully reproduce the physical signal because of symbolic notes。Only when the annotation becomes technical rather than symbolic，Direct simulation of sound signals，Records of vibration and sound waves，can truly refer to sound。

If the ancient Greek alphabet watches monopolized the field of acoustic technology for thousands of years，So the first media device to break the monopoly is a voices。Device that can record and analyze signals，The energy of turning sound waves into metal needle vibration，and reappear sound signal with uneven gully，Diagrams。The chart bet365 live casino games of the sound is essentially different from the annotation file of the alphabet era，Try to record the true sound of physics for the first time，But the noise is also recorded while recording the vocals。The ability to reproduce the real voice of the vocal machine is limited，But the mission of the sound of decoding secrets is enough。Edison foresee，The voices invented by your own invention can be used as an impeccable "witnesses"。in the novel "Dracula" of Bram Stoker，Dr. Seward (Seward) uses a vocal machine，Not only records the analysis of the event，And record the nonsense of mental patients and the rustling sound of bat flight，It provides an important technical guarantee for the hunting "vampire"。

The broadcast that appeared later，is to let the recorded real voice take radio，Implementing sound instant、Non -fixed Sprinkle。Records of the vocal machine、Play function，Decoding into a radio code and the decoding of the radio。From the perspective of the evolution logic of the technical itself，We might as well take the voice machine、Phone、Radio Broadcasting, etc. It is called acoustic technology medium，The alphabet watch that distinguishes as a symbolic medium。From this perspective，The significance of broadcasting is not limited to the mass media and its social functions，It is evenly to form a "technical association body" with other acoustic technology devices，Breaking the monopoly of the letters in the field of sound treatment。Since then，The sound begins to get processed in the "black box" of the technical device，No longer a symbol that can only be treated with human visual treatment。

Media archeology survey of sound makes us realize，Media history is not only the history of the mass bet365 live casino games media，The media is before becoming a mass media，It is a cultural skill or experimental device。Humanities cannot pay attention to the sound defined by the ears (SONIC)，Also pay attention。Especially in the era of acoustic technology，Volkswagen media is only a way of existence of acoustic devices，More basic is its own technical group。

For modern people who are accustomed to understanding the media with popular media，The technical nature of the medium is often in the background without being noticed，The prospect is the media content。In fact，Entering the home of ordinary people，Technical nature is the prospect。For example，Edison described the voice machine as "talking machine"，As for what it is said, it is secondary; Benjamin believes that the essence of film and traditional drama is the impact of technology itself on people: the intermittent effects of movie editing technology can block hallucinations，Paralyze the audience's emotional ability。After the emergence of commercial broadcasts，Some commentators compare the radio program to "Like radio and telegraph、Printing combined to broadcast news and weather forecast "，In fact, the most common broadcast content at that time was records (news and weather forecast was a common content of newspapers since the 19th century，Need a telegram to pass)，Critics obviously attach more importance to the change in the technical form of "radio communication sound"。

Of course，The content is not completely unimportant，Just say，Only when the medium as an experimental device or war technology is used as a mass communication medium，The content will only reach the front desk。Historical materials excavated according to Kidler，As bet365 Play online games early as the first few years of the 20th century，Professor of Berlin University of Technology developed the "broadcast" for serving the empire monarch，Let the singer of the male treble (Enrico Caruso) sing from the bell -shaped mouth of the voice machine，Then pass through the high -frequency radio wave "through the hustle and bustle metropolis to our ears"。After World War I，Due to the technology that guarantees the radio of the army，Civil Broadcasting in Germany gradually developed。

　　Acoustics of the Digital Age

In the current digital technology era，The existence of the sound has changed again，Incorporates into the data stream processing by the computer。Compared to the era of simulation technology，The information processing ability of digital technology can be said to increase another number of magnitude，Not only can all the files in the past process the data flow of all forms of the past，can even conduct archaeological research on the media in the past，Records that cannot be restored in the era of simulation technology。Wolfgang Ernst pointed out: "Today，Optodigital Reading，enable us to hear the sound we could not hear again; use the sound as an image for optical figures，You can break down any meaningful unit into discrete blocks，These discrete blocks，Only by operating technical mathematics (Technomathematical Diagrams) can be analyzed by humans。”

The meaning of the computer for today，Equivalent to the meaning of the alphabet to the ancient Greeks -general processor that can process all information。Monopoly of a single medium (letter table) broke by modern technology devices，Re -establish it from the digital medium。From this，Cultural skills/media bet365 best casino games technology completed its own recursive。
