What is sound recording?, Miami beach Coral Gables  Sound recording and reproduction is an 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. Recorder Buy Miami Beach Coral Gables

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 bigger loudspeaker diaphragm causing changes to atmospheric pressure to form acoustic sound waves.

Digital recording and reproduction converts the analog sound signal picked up by the microphone to a digital form by the process of sampling. This lets the audio data be stored and transmitted by a wider variety of media. Digital recording stores audio as a series of binary numbers (zeros and ones) representing samples of the amplitude of the audio signal at equal time intervals, at a sample rate high enough to convey all sounds capable of being heard. A digital audio signal must be reconverted to analog form during playback before it is amplified and connected to a loudspeaker to produce sound.

Prior to the development of sound recorders, there were mechanical systems, such as wind-up music boxes and, later, player pianos, for encoding and reproducing instrumental music.

Pre-history of recorders.

Long before sound was first recorded, music was recorded—first by written music notation, then also by mechanical devices (e.g., wind-up music boxes, in which a mechanism turns a spindle, which plucks metal tines, thus producing a melody). Automatic music reproduction traces back as far as the 9th century, when the Banū Mūsā brothers invented the earliest known mechanical musical instrument, in this case, a hydropowered (water-powered) organ that played interchangeable cylinders. According to Charles B. Fowler, this “…cylinder with raised pins on the surface remained the basic device to produce and reproduce music mechanically until the second half of the nineteenth century. The Banu Musa brothers also invented an automatic flute player, which appears to have been the first programmable machine. According to Fowler, the automata were a robot band that performed “…more than fifty facial and body actions during each musical selection.

In the 14th century, Flanders introduced a mechanical bell-ringer controlled by a rotating cylinder. Similar designs appeared in barrel organs (15th century), musical clocks (1598), barrel pianos (1805), and musical boxes (ca.1800). A music box is an automatic musical instrument that produces sounds by the use of a set of pins placed on a revolving cylinder or disc so as to pluck the tuned teeth (or lamellae) of a steel comb. They were developed from musical snuff boxes of the 18th century and called carillons à musique. Some of the more complex boxes also have a tiny drum and/or bells, in addition to the metal comb.

The fairground organ, developed in 1892, used a system of accordion-folded punched cardboard books. The player piano, first demonstrated in 1876, used a punched paper scroll that could store a long piece of music. The most sophisticated of the piano rolls were “hand-played”, meaning that the roll represented the actual performance of an individual, not just a transcription of the sheet music. This technology to record a live performance onto a piano roll was not developed until 1904. Piano rolls were in continuous mass production from 1896 to 2008. A 1908 U.S. Supreme Court copyright case noted that, in 1902 alone, there were between 70,000 and 75,000 player pianos manufactured, and between 1,000,000 and 1,500,000 piano rolls produced. The use of piano rolls began to decline in the 1920s although one type is still being made today. Recorder Buy Miami Beach Coral Gables

Electrical recording Miami beach Coral Gables

Between the invention of the phonograph in 1877 and the first commercial digital recordings in the early 1970s, arguably the most important milestone in the history of sound recording was the introduction of what was then called electrical recording, in which a microphone was used to convert the sound into an electrical signal that was amplified and used to actuate the recording stylus. This innovation eliminated the “horn sound” resonances characteristic of the acoustical process, produced clearer and more full-bodied recordings by greatly extending the useful range of audio frequencies, and allowed previously unrecordable distant and feeble sounds to be captured.

How Does a Recorder works, Miami beach Coral Gables

If we talk about a magnetic tape recorder like the cassettes (stone age) the principle is quite simple. The trick is in electromagnetism. If a coil of insulated copper wire brings a magnet close to you and moves it quickly, you can measure an electrical current at the ends of the wire coil.

Now, an audio-head reader is nothing more than a very thin coil of wire against which a large number of small impregnated magnets are rapidly circulated on a flexible tape. The intensity of the magnets and the orientation of the poles causes the current induced in the reading head to reproduce the pattern present in the tape, hence it is only amplified. Recorder Buy Miami Beach Coral Gables

And now how is that pattern introduced to the tape?

During the recording process, the procedure is the reverse. It is circulated through the coil of a recording head (for the case identical to the player) an electric current that will generate a magnetic field that will follow the pattern of the current (music, digital information etc.) and will be passed in front of it a tape flexible impregnated with small iron filings that will be magnetized and oriented according to the magnetic field pattern of the recording head.

 Digital Sound Recorders, Miami beach Coral Gables

The advent of digital sound recording and later the compact disc (CD) in 1982 brought significant improvements in the durability of consumer recordings. The CD initiated another massive wave of change in the consumer music industry, with vinyl records effectively relegated to a small niche market by the mid-1990s. However, the record industry fiercely resisted the introduction of digital systems, fearing wholesale piracy on a medium able to produce perfect copies of original released recordings. However, the industry succumbed to the inevitable, though using various protection system (principally Serial Copy Management System, or SCMS). Recorder Buy Miami Beach Coral Gables

Technological developments in recording, editing, and consuming have transformed the record, movie and television industries in recent decades. Audio editing became practicable with the invention of magnetic tape recording, but digital audio and cheap mass storage allows computers to edit audio files quickly, easily, and cheaply. Today, the process of making a recording is separated into tracking, mixing and mastering. Multitrack recording makes it possible to capture signals from several microphones, or from different takes to tape, disc or mass storage, with maximized headroom and quality, allowing previously unavailable flexibility in the mixing and mastering stages. Recorder Buy Miami Beach Coral Gables

Recording Software, Miami beach Coral Gables

There are many different digital audio recorder and processing programs running under several computer operating systems for all purposes, ranging from casual users (e.g., a small business person recording her “to-do” list on an inexpensive digital recorder) to serious amateurs (an unsigned “indie” band recording their demo on a laptop) to professional sound engineers who are recording albums, film scores and doing sound design for video games. A comprehensive list of digital recording applications is available at the digital audio workstation article. Digital dictation software for recording and transcribing speech has different requirements; intelligibility and flexible playback facilities are priorities, while a wide frequency range and high audio quality are not. Recorder Buy Miami Beach Coral Gables
