At present, music file playback format is divided into two kinds of lossy compression and lossless compression. Using different formats of music files, there is a great difference in the performance of sound quality.
Common to MP3, WMA, Ogg is called lossy compression, lossy compression by definition is to reduce audio sampling frequency and bit rate, the output of audio files will be smaller than the original file.
Another kind of audio compression is called lossless compression, can save the original file in 100% of all the data, the volume of the audio file compressed smaller, and after the compressed audio file restore, can achieve the same size as the source file, the same rate of code. Lossless compression formats include APE, FLAC, WAV, WavPack, LPAC, wmalossless, applelossless, TTA, Tak, TAC, La, Optimfrog, Shorten, and common, The mainstream lossless compression format currently has ape, FLAC, TTA, TAK, WAV, the general CD is lossless music.
The difference between non-destructive music and ordinary music
Different sizes
Common MP3, WMA and other formats of a single hand song occupies about 1m-5m, and ape and FLAC and other lossless format music, the single song occupies space size can generally reach dozens of trillion, or even hundred m above;
Different format
Ordinary music format for MP3, WMA, OGG and other formats, and the lossless music format is often ape, FLAC, TTA, TAK, WAV.
Bit rate is different
Ordinary music, such as WMA is generally 128kbps music, MP3 is more than 128 or 192 or 320kbps/, while the lossless music bitrate generally reach the 800-900kbps, the traditional CD even reached 1411Kbps, the use of lossless compression, the sound quality is the most perfect.
Note: bit rate (Kbps) refers to the transmission rate of the digital signal, that is, the number of thousands of messages per second (k for thousands, KB is the number of thousands of bits), for music, the larger the theoretical value, the better the sound quality.
Introduction Here, I believe that the difference between the lossless music and ordinary music has been understood, now the question is, when downloading music, we should choose MP3 or lossless quality?
The general MP3 music bit rate reaches 320kbps, its sound quality is very good, but the lossless music bit rate generally is in 800-900kbps about, even higher. Using a computer or mobile phone to listen to songs, it is difficult to hear the MP3 music and the difference between the music, need to use a fever headset or professional to hear the nuances.
In general, lossless music quality is undoubtedly the best, to be free to download, of course, choose priority Download, but in view of the lossless music occupies a large space, and the general people can not hear the difference, unless the use of a number of fever headphones and other equipment to hear the nuances, so ordinary users generally download MP3 music Except for professionals or music enthusiasts.
