Flac vs mp3

Recently, FLAC-compatible players, which are highly appreciated by most audiophiles, have developed rapidly. What is the secret of the format? Why is the popular mp3 format not suitable for music lovers?

The birth of mp3
In the early days of digital audio, the first music format was Wave, which was widely used on CD-Audio discs. There were no large hard drives at the time and the 700MB album seemed very large. With the advent of high-performance microcircuits, the mp3 format was invented, allowing music to take up 10 times less disk space (~ 70MB vs. 700MB). This made it possible to significantly increase the number of musical compositions stored by listeners at home on a computer and early Flash players. Due to its high weight, the original format was replaced by the mp3 boom.
Many people remember the incredibly popular iriver players that support mp3 and ogg, but the time for those players has passed and iriver has released Astel & Kern players that support FLAC in high resolution.
Compression of information in mp3 and quality How does mp3 take up less space? It is based on two technologies: archiving and psychoacoustic compression. The conventional file is not very efficient and is only used in lossless formats like flac, ape, and wavepack. Psychoacoustic compression is added to mp3 and this format belongs to the Lossy group (lossy compression).
Psychoacoustic compression dilutes data according to a simple principle: anything that the listener potentially does not hear (for example, quiet sounds against the background of loud sounds) is mercilessly discarded. There are many parallels with the video and the photos. For example, in the jpg format, pixels with similar colors are grouped into large squares of the same color and when forming an image, we usually do not notice that various hues have disappeared. But if we want to take a closer look, we will definitely see it!
The quality of the same mp3 bit rate is different
There are a large number of mp3 encoders, and each has its own priority level in the algorithm, what is least important in music and what to remove first with low compression and last with high. The higher the compression, the more meaningful information is removed and the easier it is to listen to on simple audio equipment.
Unfortunately, the sound quality of mp3 depends not only on the degree of compression expressed in bitrate, but also on the codec with which it was compressed and with what settings. Very often, a high bit rate on the order of 320 kB / s is used, but with the fast and less resource consuming encoding mode. The file encodes very quickly, but as a result, it subjectively sounds worse than encoded at 128 kB / s in long, resource-intensive mode.
Almost all “mp3 producers” in the form of websites and CD compilations use fast algorithms. They believe that most will not hear the difference on their phones anyway, and will be guided by the purchase only by the bitrate. Why spend the extra effort if they buy well?
The differences between the 320 kB / s mp3 encoded in high quality and resource intensive mode and the original Wave are actually very small and sometimes difficult to distinguish even with good audio equipment, but these mp3s are usually very few and far between. they just make them enthusiastic. Most of the mp3 leaves a depressing impression.
Much also depends on the decoder, which determines the quality of the final sound. There are still battles on the forums, which software or hardware player sounds better with which decoder.
At the height of mp3 development, the quality of players and sound cards left much to be desired, especially considering that the main mp3 users were those who could not afford to listen to music on a good hi-fi system. . Quality issues were hardly noticed, similar to JPG compression issues when viewed through a cell phone screen. But on a good audio route, it was obvious. Recently, technology has advanced and the quality of most fonts has increased and consequently the disadvantages of mp3 have become more obvious. What are the main disadvantages of mp3 sound?
The absence or unnaturalness of the high frequencies (due to the strong decimation of the high frequencies, which most supposedly cannot hear)
Wheezing and distortion in vocals, unnatural timbres of instruments
Violation of the location of sources in space.
But most importantly, you never know how high quality an mp3 will sound, how much information is actually lost on it.
