Sound and Recording: Applications and Theory
Recording sounds using mechanical or electronic methods is quite deferent from notifying data or information. Recording method varies from visual to audible.
There is a diverse range of recording medium including scripting, photographing, and drawing etc. Sound recording implies to preserve for listening again in future. However, recording sound differs from preserving an object visually. In that sense, recording sound can be defined as a progression of codifying or storage of human speech or singing, sound pertaining to instrumental music or sound effects using electronic or mechanical methods.
This can be understood as a result of the scientific revolution. There are four kinds of sound recording technologies that have emerged so far since the evolution of sound recording. Similarly, as far as the methods and procedures are concerned four kinds of recording eras can be identified as Mechanical era, Electronic era, Magnetic era and Digital era that have continued from the early times to modern periods 1. They are: 1 Mechanical or acoustic recording 2 Electronic recording.
That is the initial and practical method of recording sounds. Sound grooves on the recorded medium wax or other medium were produced by the mechanical vibrations of a needle, which was connected as stylus to one end to the membrane and the other end to large horn that employed as a microphone.
In this recording process, sound was recorded as a visual image into the membrane or the recording medium 2. Electrical Sound RecordingElectrical recording emerged as a result, of scientific experiments and innovations. In the Electrical recording progression, sound is recorded using electronic devices such as microphones, amplifiers and other appropriate equipment such as electrical record cutters rather than phonograph horn that was used to record sound mechanically.
The sound quality of electrical recordings did not have harsh sounds like in mechanical recordings and it improved the sound quality of recordings. However, the technology of electrical recording did not change the practice of live group performance.
Both Magnetic and Digital recording technologies can be considered as evolutionary and advanced methods of sound recording. Types of RecordingEven though this technology is basically classified based on the time periods and its advanced features, the functionalities and the process of it permit one to discuss three major headings as follows Live recordings Pre-production 2.
Track recording Post-production 3. Programming Live Recordings Pre-Production Sometimes, the musical performances are simultaneously recorded on specific mediums. All the recordings that were stored on the previous storage mediums such as wax were cut to such mediums at the same time of recording.
However, this method is not employed very often and it is not considered to be a proper and practical method of recording of musical data. However, this is used to record live concerts and folk music performances especially, for preservation. The live beams of programs that are broadcast are employed the same method of recording 4.
Track Recording Post-production With the introduction of magnetic recording with different track counts, the technique of track recording came into existence as a practical method of sound recording. According to this method, music is recorded using certain recording equipment especially microphones on its own track. Finally, all the recorded tracks are mixed once the recoding process is completed. This principle is commonly used presently due to its convenience and practical simplicity 5.
ProgrammingProgramming is commonly used in the field of computing vocabulary. It is related to the field of computers. The concept was adopted in the field of music with regard to the gradual development of computer based music recording and production technologies.
With the development of the digital music recording technology, which is based on software and MIDI devises, both composing music and recording came to be known as music programming. Storing programmed and manipulated data of music in a compatible medium by means of software and certain other equipment is called 'programming'.
As a result, the position of 'sound engineer' is sometimes replaced with that of the 'music programmer'. There are two existing forms of recording. They are; 1 Analog recording and 2 Digital recording. In analog recording method Analog means that the electrical signals consist of continuous changes in electrical voltage rather than a discrete series of numbers as in modern digital format 6 , waves of sounds produced by human voices or acoustic musical instruments are recorded as physical texture on the medium.
But when record the same analog data onto a tape medium it converts into electrical signals and are then stored on a tape. On the contrary, Digital Recording is a process of transcribing sounds or data into binary or numeric format Is and 0s while recording is taking place. The process of transforming analog signal to digital is performed by a converter called "analog to digital converter" ADC.
In contrary to analog recording the most compensation of digital recording has duplicate number of copies without losing the sound quality as well as, copies can also be made of copies without the sound being degraded.
This facility is highly supportive for editing purposes. However, both forms of recordings have their own distinctive characteristic qualities.
When consider to both analog and digital forms digital is in advance as a format since its higher solidity. As far as both formats are concerned analog recording is like a painting while the digital is like a snap shot of a natural thing. Sound Recording studioThe place where especially designed for capturing and recording sound is commonly known as recording studio.
Normally recording studio consists of two rooms such as; control room and studio room. All necessary recording machineries and sound manipulation devises sound mixer, amplifiers, recorders etc. As far as the functional usages are concerned, modern recording studios are classified under four headings such as: Professional studios especially for commercial purposes , Audio-for-visual production environments film and other media purposes , Project studios 7 these types of studios are designed for personal use.
Where the functional usages are concerned, modern home recording studies are fall into "project studios". However, with the development of computer based music recording technology, the concept of home recording studies was emerged.
Accordingly, the above mentioned principles and concepts began to vanish and bed rooms, garages and other room spaces are utilized for recordings and portable studios used by journalists 8. Similarly, recording studios are classified under the technology in which is utilized as: 1.
Analog studios, 2. Semi digital studios and 3. Fully digital studios 9. Before the concept of studio emerged, specific rooms, covered spaces and locations were especially prepared and utilized according to the suitability for recording.
But with the gradual development of recording technology, sound studios are came in to existence and expanded according to audio acoustic architectural concepts and principles and also compatible with modern recording technologies. Early Attempts to Record SoundsBy inquiring into the history of sound recording one can assume that scientists have been making many efforts to record sounds. It is reported that, in the 16 th century, a natural scientist named Giovanni Battista Della Porta had done some experiments with recording and reproducing sounds using a tube.
He thought that he would be able to listen to his own voice just after speaking to the tube and covering it immediately. But the effort he made did succeed Another attempt to record sound was made by a Swiss watch maker named Smooth Nikola in He had tried to record sounds through a machine called "Musical box". But it too failed like the former one. This can be considered as the first devise or the first method of recording sounds in the history Leon Scott of France was the first person to record live sounds.
The device invented by him to record sounds was known as Phonoautograph. It was invented around This machine had a horn shaped devise that worked as a microphone in order to direct sounds towards the diaphragm placed at the end.
The stylus was attached to the diaphragm used to scratch out a wave line on a revolving cylinder according to the wave length that is passing through the horn.
To record the sound wave, the cylinder was layered with lampblack that may be applied by holding it over a flame to accumulate carbon. However, due to the lack of sensitivity, this device was not sufficient enough to properly reproduce the recorded sound. By using this device only a very short sound track less than one second could be recorded.
Even though it was not successful as a sound playback technology, it had a good demand as a scientific research object Graphophone by Alexander Graham BellMore than two decades after the invention of Phonautograph by Leon Scott, in , Alexander Graham Bell experimented on the ways of improving the aforementioned recording device in terms of a mechanism similar to the functional pattern of the human ear.
Even though he started his research to develop his recording device ear Phonautograph, it was in that he was able to introduce the improved machine especially designed for dictation purposes. That instrument is now known as Graphophone He structured the entire machine in a similar manner to the ways in which the organs are positioned in the inner human ear. Like his contemporaries, he used cylindrical mediums for recording data as well.
But the main deference between phonautograph and graphophone was the medium that was coated on the cylinder. Leon Scott coated the cylinder with lampblack whereas Bell used wax cylinders for his device. Graphophone was used for dictation purposes. Phonograph by Thomas EdisonIn , the well-known scientist Thomas Edison was able to discover a device for recording and playing back human voice for the first time in the world history. He had invented this device while he was experimenting with the ways of improving the telephone introduced by Alexander Graham Bell in
Sound and Recording
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. 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.
