DIGITAL vs ANALOG RECORDING
Digital recording/ reproduction converts an analog sound signal picked up by a microphone to a digital form. The process that allows this is called digitization. This allows the recording to be stored and transmitted by a wider variety of media. Digital recording stores audio as a series of binary numbers. These represent samples of the amplitude of the audio signal at equal time intervals. The sample rate is high enough to convey all sounds that can be heard. Digital recordings are of better quality than analog recordings because the digital format prevents much loss of quality found in analog recording which is due to noise and electromagnetic interference in playback. Mechanical deterioration and damage to the storage medium is also prevented. A digital audio signal has to be reconverted to an analog form during playback before it is applied to a speaker or earphones. Analog recordings rely on making an exact copy of the sound-wave pattern. Making more copies of the original recording can distort the pattern and add extra noises. Because a digital recording is just numbers, it can be copied as well as corrected if necessary. This can be done many times, without any damage to the recording.
SOUND RECORDING
A brief introduction to, and the history behind the science of Sound Recording
WHAT IS SOUND RECORDING?
Sound recording and reproduction is defined as an electrical or mechanical inscription. This is a re-creation of sound waves, irrespective of the source. The two main classes of sound recording technology are analog recording and digital recording. Since 1934, sound recordings (or phonograms) have been treated differently from musical works under copyright law. Copyright, Designs...

... notes of bass musical instruments are around 100 vibrations per second while high notes from flutes and tin whistles are about 1,000 vibrations per second. Bats use sound waves (echolocation) as high as 50,000 vibrations per second but these are outside of our human range (ultrasonic). The ability to quantify physical behaviours is central to building a structured understanding of the system we use to record sounds, and mathematics allows this. The science of measurement of air pressure and velocity of our recorded sound, and the physical and mechanical systems that use gases to transmit sound waves into electrical signals. Is involved. The science behind the actual recording requires mathematics, physics, acoustics, electronics, and more recently psychoacoustics, to explain how we translate physical air vibrations into musical sound that excites our emotions.
In 1904 Eugene Lauste successfully recorded sound onto a piece of photographic film. This invention was known as a “Sound Grate” the results where still far to crude to be used to public display.

The Helmholtz resonance of a guitar is due to the air at the sound hole oscillating, driven by the springiness of the air inside the body. This is analysed quantitatively in Helmholtz Resonance.

Thesis Statement: The vinyl record, though underappreciated and often overlooked, has a rich history and interesting process of creation.
A timpani is one of the percussion instruments that has a definite pitch. They are also struck by a mallet on the surface of the drum, which is made out of calfskin and is stretched over a copper shell.(1) When analyzing the mallets many notice that they are home made. Timpani’s come in all different sizes, which determines the change in the pitch. They can come in sizes such as a thirty-two inch, twenty-nine inch, twenty-sixth inch, twenty-three inch and the smallest is a twenty inch, which is a higher pitch than the larger timpani’s.(2) Some sound characteristics of a timpani might be evaluated by words such as powerful, deep, booming, or hollow. Timpani’s also create their sound by a petal located at the bottom of the
The Use of Electronic Technology in 20th and 21st Century Music In this essay, I have examined the use of electronic technology within 20th and 21st Century music. This has involved analysis of the development and continuing refinement of the computer in today’s music industry, as well as the theory of the synthesiser and the various pioneers of electronic technology, including Dr. Robert Moog and Les Paul. Also within the essay, I have discussed the increasing use of computers in the recording studio. The computer has become an indispensable tool in ensuring that both recording and playback sound quality is kept at the maximum possible level. Many positive ideas have come from the continued onslaught of computerisation.
Sounds are produced by the vibrations of material objects, and travel as a result of
Astronomer Galileo Galilei observed that the entire universe “is written in the language of mathematics.” As an avid musician, I chose to study the topic of how math applies to music, more specifically how sound waves are transmitted. My passion for music urged me to research the sounds that are made and how they are produced.

...ats such as paper based and microfilm. Compare to paper based, it does not change the form of paper even how many years pass. With the proper care of the records, record center or an organization can keep the record almost thirty years until the process of destruction. However, it could not happen to an electronic record, because technologies rapidly change. There always have new software or hardware that will be upgrade and become more advance. Actually, even under the best storage conditions, digital media have a very limited shelf life, generally less than thirty years. The efforts to preserve the physical media thus provide only a short term, partial solution to the general problem of preserving digital information. Given such rates of technological change, even the most fragile media may well survive the continued availability of equipment to read those media.
The Scholar: I think that's more a function of sound wave vibration than anything else.
Live and recorded music have many differences that make each unique and enjoyable. Live music may be more costly and time consuming, but it is more energetic and interesting than recorded music. Live music can be dangerous and cause hearing problems, yet concerts are still selling out. Recorded music is cheaper and can be accessed almost anywhere, but it is not as exciting. Even through these differences, both types of music have the same basic structure, and is served as entertainment purposes that many individuals
Sure, there are times when we listen carefully to the music behind the songs we hear, we may focus on the rhythm or the harmonies, but we never think of what it took to make the sounds that we are hearing. In this paper, I will explain the physical musical instruments. I will describe and define sound in psychic terms and then describe how different instruments create their unique sounds. There are so many different kinds of music, and thanks to the variety of instruments, the combinations of sounds that we can make are limitless. Before we look at musical instruments, we have to look at music itself.
