Since I was a little girl, I liked listening to music, especially in the most antisocial way: using headphones. My fantasy for portable music players began when I borrowed a cassette player from my mother when I was little. There is nothing that gives me more energy for a career than Kendrick Lamar’s perfect song. In the same way, there is nothing more humiliating than having to stop suddenly because my tired limbs got stuck in the wires of the headphones sending my phone flying out of the running tape. An Mp3 player or digital audio player is a device that stores, organizes and plays digital audio files. There are mainly three types of digital audio Mp3 players:
– MP3 CD players: devices that play CDs. Often, they can be used to play audio CDs and home data CDs that contain MP3 or other digital audio files. The player had the capacity of 16MB (if we are talking about MB), allowing the reproduction of 1 hour of music in audio quality, using some MMC cards could be increased to 64MB to have 5 hours of music (with poor quality), however, at that time the most were 128MB players (we are talking about the pre-iPod era). see how we have advanced in this area, thanks to the iPods people got used to having all the music in digital and with the arrival of smartphones, it is not necessary to have another device but your phone itself plays this music.
Portable audio player
This package includes a player with 16 GB Micro SD card, USB cable and a headset. Equipment compatible with a wide variety of languages: English, Italian, French, Chinese, German, Spanish, Dutch, Polish, Portuguese, etc.
It is small, so it is ideal to carry without problems when running. It can easily fit in a pocket by its dimensions of 7x6cm. It has a very good critique by the users who have tried it, who affirm positively and efficiently, that “It is easy to use and sounds wonderful.” The name itself is inappropriate, since most of the MP4 players are incompatible with the MPEG-4 Part 14 standard or container format .mp4. Instead, the term symbolizes their status as successors of MP3 players, wanting to associate it with the ability to play video. The innovation did not come from Silicon Valley, but from Bavaria: scientists from the Fraunhofer-Institut für Integrierte Schaltungen, in the town of Erlangen, racked their brains to try to develop a medium that would retransmit the music with the right tone quality. Twenty years ago that format of digital music received its name: the “MP3”.
The two letters and the number were an abbreviation of the complicated technical name for compressing ISO ISO 11172-3 “MPEG Audio Layer 3” audios.
The current evolution of audio compression has left behind the era of the MP3 reproducer. Nowadays, to listen to music when you move, you do not need much storage capacity, but bandwidth for streaming. And also in this sense the German discovery plays a considerable role: “The MP3 is not only for music on the PC,” says Grill. Rather it is a standard music format for everything. “At present there are probably active tens of thousands of streaming services with MP3.” The rest uses mostly formats such as the AAC (successor to the MP3) and that was also developed by Grill and his colleagues.
The mp3 is a format of compressed digital audio with loss in which you can record or enter audio information which is compressed in a memory but as the word says compression with loss is that once compressed the information is not You can recover in its original form.
This equipment was able to read this musical information due to the software, which transforms these codes during compression into an electrical signal in order to be heard. The MP3 format became the standard used for audio streaming and high quality audio compression.
Some of the advantages of mp3 are:
– The possibility of adjusting the quality of the compression, proportional to the size per second (bitrate), and therefore the final size of the file.
– Files that occupy a large space can now be reduced to 12 and even 15 times less than the original uncompressed file.
With the increase in the use of the Internet in the world of computing, the exchange of audio files became more accessible to the user with the creation of this format.
The quality of Pono is that the main format in which it plays music is the so-called FLAC (Free Lossless Audio Codec), which can sound up to 30 times better than an MP3. However, Pono can read files in ALAC, MP3, WAV, AIFF or AAC formats. The triangular design of the player is very striking, and the promise of being able to listen to music with the quality that supposedly touched so many celebrities in the promotional video do very eye-catching. Those who want a Pono can invest at least 300 dollars in the Kickstarter campaign to receive the yellow or black version; If you want the edition with signatures of famous musicians engraved on the surface you must invest 400 dollars or more. Deliveries are estimated for October of this year.
The player designed for true music lovers who know how to distinguish each sound in the songs seems to be a success, however, it reaches a market in which even the Apple iPod has lost importance in front of the cell phones that fulfill the function all-in -one.
