When downloading music, we often see these options: lossless sound quality and normal sound quality, lossless sound quality requires members to download, otherwise only normal sound quality can be downloaded. Since it is a fee, the lossless sound quality must be higher than the normal sound quality, so what are the differences between them?

Different compression encoding methods
Commonly seen MP3, WMA, OGG are called lossy compression. As the name suggests, lossy compression is to reduce the audio sample rate and bit rate, and the output audio file will be smaller than the original file, which is normal sound quality. we often see.
Another audio compression is called lossless compression, which can compress the volume of the audio file to a smaller size on the premise of saving 100% of all the data in the original file. Same size, same bitrate. Lossless compression formats include APE, FLAC, WAV, WavPack, LPAC, WMALossless, AppleLossless, TTA, Tak, TAC, La, OptimFROG, Shorten, while common and conventional lossless compression formats today include APE, FLAC, TTA, TAK, WAV, Generally CDs are lossless music.

different file sizes
Common MP3, WMA and other formats occupy about 1M-5M space for single-handed songs, while for music in lossless formats such as ape and flac, the space occupied by a single song can generally reach tens of megabytes, or even more than 100M.
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). For music, theoretically this The higher the value, the better the sound quality. Ordinary music, such as WMA, is generally 128kbps music, MP3 is mostly 128 or 192 or 320kbps/, while the bit rate of lossless music generally reaches 800-900kbps, and traditional CD even reaches 1411 Kbps. Using lossless compression, the sound quality is the most perfect.

different sound
The feature of lossless music is that regardless of whether there is sound between the beats, its data always flows smoothly, so the fast magnetic vibration in your headphones is stable, and the sound is natural and real; while lossy formats such as MP3 are due to the loss of people The ear can not hear part 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 magnet block vibrates excessively and unstable, which will produce burr noise. If professional equipment is used, it is easy to hear right and wrong.
