How Audio Products Work
There are several standard music distribution formats. The MP3 and the
compact disc (CD) are the two most common at the moment, but cassette
tapes are still around. The Sony Minidisk is another format that Sony
has been trying to popularize for many years. A Minidisk looks a lot
like a floppy disk but is slightly smaller (7 cm, 2.75 inches square).
CDs store 74 minutes of music in a nearly indestructible form and have
the advantage of being a digital format, but until fairly recently you
could not record on a CD. The Minidisk's main claim to fame is that it
is (and always has been) recordable.
One easy way to think about a Minidisk is like a floppy disk -- you
can record and erase files on a Minidisk just as easily as you can on
a floppy disk. The big difference between the a Minidisk and a floppy
disk is that a Minidisk can hold about 100 times more data.
Minidisks come in two forms:
1 Pre-recorded
2 Blank and recordable
A pre-recorded Minidisk is exactly like a CD, except smaller. A CD
holds about five times more data (650 megabytes in data mode and 740
megabytes in audio mode) than a Minidisk. However, both CDs and
Minidisks can store the same amount of music (75 minutes or so). The
difference is that a Minidisk uses a digital compression technique
called ATRAC (Adaptive Transform Acoustic Coding) when storing music.
A recordable Minidisk is a magneto-optical device capable of storing
140 megabytes of information. Music can be scattered all over the disk
and the player can "put it together" correctly when playing the disk.
This means that you can erase and re-record songs on a Minidisk
without having to worry about how they fit together. This is
tremendously convenient compared to a cassette tape, where you have to
basically re-record the entire tape if you want to change any of the
songs on it. There are also 4-track Minidisk recorders for musicians,
Sonance is a well-established company providing high quality customized speakers for in-home entertainment. After launching their Sonance 1 model, they progressed into multi-room amplification and eventually designed the first built-in system that would support the iPod. Operating as a lean organization with only 60 employees, they relied heavily on a network of dealer and installer word-of-mouth advertising. By 1999 Sonance had reached $46 million in sales. Similar to other companies affected by innovations in technology, Sonance was forced to change strategic direction in the early 2000’s. The newly acquired leadership needed to redefine marketing efforts in response to increasing low cost competitors. Major
Phillis Wheatley, a poet of early modern poetry discloses a sonnet to Scipio Moorhead labeled To S.M., a Young African Painter, on Seeing His Works. The start of Wheatley life was being purchased by a white family and shipped off to Boston. She was an extremely intelligent child that was beginning to learn how to read, write and how to strongly connect to the Bible. When knowing the background of this poet, we realize first-hand how her childhood impacted her poetry. This piece of poetry was in the point of view of first person. Many poets use a type of sound devices or figurative language to enhance their message within. Wheatley introduces a sound device known as end rhyme as a way of intensifying the experience to the reader. The poet stated, “When first thy pencil did those beauties give, and breathing figures learnt from thee to live” (409) uses end rhyme to give connection between those two lines. My outsight on these two lines would be summarized as the poet trying to interpret the beautiful people the artist has drawn in her own words. Also, Wheatley communicates figurative language into this poem by using the several metaphors to put emphasis on her writing. The metaphor heavily absorbed by me would be, “Whose twice six gates on radiant hinges ring: Celestial Salem blooms in endless spring” (410) creating an image of Heaven.
How a record player works is quite simple. A motor is somehow connected to a solid disc so that the disc is rotated at a constant speed. On top of the rotating disc (platter), The record is placed on top, with a slip mat in between. The slip mat can serve two functions. In the past to hold the record in place so that it would not rotate independently of the platter. Now, however, the slip mat serves a much different function. Instead of holding the record in place, the slip mat is now used to reduce the friction between the spinning platter and the record. This way a DJ can scratch (manually move the record, usually at high speeds) the record while the platter continues to spin underneath. Once the record is rotating, a stylus glides along the grooves and picks up the vibrations, these are then converted into audible sound.
I. Almost everyone has a car stereo of some sort in their automobile, however not everyone understands how they are put together.
When it comes to recording in a modern day environment DAW’s (digital audio workstation) are an essential piece of equipment if professional standard results are desired. Although DAW’s are considered a modern technological advancement the first attempt at a DAW was in 1977 and it came from Dr. Tom Stockham’s Soundstream (See references for full description) digital system. It had very powerful editing capabilities and for its time a very advanced crossfader but was still primitive compared to today’s standard. At this moment there are 100’s of DAW’s on the market but arguably there some obvious leaders. Avid’s Pro Tools has been the go to DAW for any professional studio for the past 20 years and although there have been rumors of Avid going out of business and the features in Pro Tools becoming dated, Pro Tools is still a viable option for studios worldwide. Logic Pro has risen to the fore-front of the industry in recent years due to its easy to use interface that is possible of producing professional results. Ableton Live strays away from a hardware instrument music environment to cater for electronic music users. Audio to MIDI is a main focus along with the critically acclaimed Max for Live used for live performances by many current EDM artists. Each individual DAW has its own pros and cons and comparing these can highlight which DAW is the best for what task.
Several assistive listening devices can improve the communication ability of deaf children. According to IDEA, every child with a disability is entitled to have access to assistive technology (California Department of Education, 2004). The California Department of Education (2004) outlines IDEA’s definition of an assistive technology device. It explains that this device consists of “any item, piece of equipment or product system…that is used to increase, maintain, or improve functional capabilities of a child with a disability” (California Department of Education, 2004, p. 1).
The history of automobile audio dates back to the early 1900s. George Frost did the earliest car audio experimentation in 1922. The evolution of car radios began in the Transitone Th-1, in 1927. The first FM turner band in cars was introduced in 1952. In 1965 the 8-track player was introduced in Ford vehicles. In the early 1960’s, cassettes were introduced, but didn’t become popular until 1977. The FM band became more popular in the 1980s, and the first car compact disc players were introduced in the 1980s. In the early 2000s XM satellite was introduced to the nation. Car audio has made such an impact on vehicles over the last seven decades. Car audio evolved from the simplest forms to the most complex forms. The model of car audio sound systems varies into each and every model of vehicles.
It is a portable storage device that can be attached to a computer through a USB or FireWire connection, or wirelessly. They have high storage capacities and are often used to back up computers or serve as a network
In High Fidelity, Rob, the protagonist and narrator, says “I find myself worrying away at that stuff about pop music again, whether I like it because I’m unhappy, or whether I’m unhappy because I like it” (168). It is obvious to the reader that Rob has a very strong relationship to pop music but also that this relationship is not as simple as the either-or dichotomy he describes it as. At first, it is an obsession that is almost pathological; by the end, it is an aid to his relationships and his idea of who he is. Rob’s relationship to music helps us understand Rob as a character through the different ways he uses it to interact in his environment – either as a crutch inhibiting his growth or as a way to aid his self-development.
The music industry impacts the lives of people from around the world. With the implementation of technology, the influence of the music industry has spread to affect anyone with access to technology. Streaming services have contributed to the increased popularity of music. While there are positive effects to being able to stream music and have multiple ways of listening to it, the music industry suffers from the lack of revenue and illegal activity associated with technology. Technology has had both positive and negative effects on the music industry by affecting how people access music and how music is produced
Even though the machine set many first it was very fragile. The needles, which the phonograph had two of (one for recording and one for playback), broke very easily and had to be replaced quite often, and the tinfoil could only be used so many times before ripping.
First of all, a sound source radiates power and this results in a sound pressure, where the sound power is the ‘cause’ and sound pressure is the ‘effect’. But still, we always have to keep in mind that sound cannot travel through vacuum, simply, because sound propagates as a wave, which creates ‘compressions’ and ‘rarefactions’, as it interacts with the particles of the medium. If there is no medium, then there are no particles and of course, there is no interaction wave-particles interaction and as a result, no sound is produced. This specific fact, was proven by Robert Boyle (17th century), a researcher who showed through multiple experiments, that a bell, ringing in vacuum medium cannot be heard. We have to mention here, that sound travels in different speed through various media.
Imagine a world without music…can it be done?? Of course not. Music is everywhere, even when we don’t realize it. In fact, there’s a piece by composer John Cage entitled “4:33” validating that such thing. Cage’s composition, or lack there of, puts an emphasis on how even in silence, the beauty of music still shines. His work consists of a pianist sitting beside a piano for four minutes and thirty-three seconds doing absolutely nothing…or so we think. In reality, though, the genuine music is the tiny sounds like the air conditioner, the whispering of people, etc. As outrageous as this might seem to some, I believe it’s genius. Like current day Audio Engineers, or Music Producers, Cage put a lot of thought into his creation prior to writing or producing it. Moreover, I believe Cage’s silent song paved the way for those employed in Audio Engineering now, and for those to come. By becoming an Audio Engineer myself, I too, want to show the world how beautiful music can be.
A storage device is the system where your computer stores and retrieves your data. Storage devices can be a hard disk drive, DVD, CD drives, Blu-Ray drives or flash drives. A computer can retrieve the data by being “commanded” to retrieve it from the storage area and retrieve it to your RAM. The RAM of the computer is your temporary memory where your data is inputted, and then processed and stored onto a storage device for permanent placement.
Headphone is the “electro-acoustic transducer for converting electric signals into sounds.” There are electronic devices shown in fig.1 and fig.2 that have similar function as headphone. However, it is not reasonable to call them headphones in modern society. In order to distinguish the headphone in this paper from other similar electronic devices, the headphone refers to the one that is held over the ear.
