Digital music involves the conversion of sound into binary numbers.
To arrive at the definition of digital music , it is essential that we first know the meaning of the two words that are covered by this expression. Music (a word that has its origin in the Greek term mousikē ) is an art based on the sensitive and logical organization of a structure composed of sounds and silences . Digital systems , for their part, take advantage of the logic of two states that are represented through two scales of electrical voltage that are replaced by a code where there is only space for zeros and ones (a system that offers the possibility of making use of binary arithmetic and logic ).
Now we can approach the concept of digital music , which attempts to describe the alternative of transforming sounds into binary numbers . Each second of audio is segmented into tens of thousands of parts (in most cases, 44,100) and, later, these small fractions are represented through a numerical value that symbolizes their characteristics.
Creation and distribution of digital music
In the field of computing , the method used to carry out this conversion is known as PCM (Pulse-Code Modulation) . In this way, a digital music file contains the binary numbers that, from the digital plane, represent the original audio.
It should be noted that digital sound is not limited to formats that are usually distributed via the Internet , such as MP3 . In reality, these are compression systems for already digitized music, which eliminate frequencies that are not possible for the human ear to capture. But digital music was already present with the appearance of the first compact discs or CDs .
In addition to MP3s, there are also other digital music players such as MP4s , iPods and even smartphones . All of these technological devices are the most used today by citizens to listen to their favorite songs, they are in great demand.
With a telephone you can listen to digital music.
Main advantages
The main reason for this large consumption of technological instruments as an option compared to other traditional systems is fundamentally due to their small size and how little they weigh, which means that they can be transported very easily. Thus, any of them can be carried in a simple pocket.
In addition to these two main hallmarks, we must also highlight the fact that these devices also offer the possibility of enjoying high quality sound, free of any type of noise, with total cleanliness and clarity. That is, they allow you to enjoy the music in question in the best way.
Reasons mentioned above to which it is necessary to add one more that, especially in recent years, has become one of the compelling reasons for its success among the population in any corner of the world. This reason is none other than that they allow you to store a multitude of songs. In this way, the owner of one of these digital music devices has the opportunity to enjoy an extensive library of their favorite songs. An example is that in just 60 Gigabytes you can save around 20,000 compositions.
All of this explains the reason for the success of this type of music and its various players.
In this regard, it is important to highlight that before the emergence of digital music, sounds were represented in mechanical or magnetic form, which is equivalent to today's digital signals. These recordings, present on vinyl records and cassette tapes , have the characteristic of being analog .
