What is the difference between lossless sound quality and normal sound quality? Part 2
different bit rates
Bit rate (kbps) refers to the transmission rate of digital signals, that is, how many thousands of bits of information are transmitted per second (k means thousands of bits, kb means how many thousands of bits). , the better the sound quality. Ordinary music, such as wma, is generally 128kbps music, and mp3 is mostly 128, 192, or 320kbps/, while lossless music’s bit rate generally reaches 800-900kbps, and traditional CD even reaches 1411 kbps. The quality is the most perfect.
different sound
The feature of lossless music is that no matter there is sound between beats, its data always flows smoothly, so the fast magnetic vibration in your earphones is stable, and the sound is natural and real; while lossy formats like mp3 are due to loss of people ear can’t hear some of the data, so the magnetic block in the earphone vibrates unnaturally, causing it to vibrate when there is sound, and do not vibrate when there is no sound, so the magnetic block vibrates excessively and unstable, which will produce burr noise. If using professional equipment, it can be easy to hear right and wrong.
Of course, whether you can hear the difference depends on the person, and there are differences in everyone’s speech recognition ability. Some professionals and those with sensitive hearing will find that there are differences, but for most common listeners, in fact, there is no difference between the lossless sound quality of normal and flac mp3, and the effect is similar.
We commented at the beginning that massive tests have been carried out on many people and 99.99% have not been able to recognize between an mp3 with good sound and a kbs of 192 or higher and a lossless.
