无损音乐格式介绍（Introduction to lossless music formats） Lossless music formats include: APE, FLAC, WAV, TAK, ALAC, AIFF, TTA, and so forth, and MP3 is not included APE Basic knowledge of APE 1, APE source file access A few years ago, we had a tape recorder and listened to the music on the tape. I thought it was good. Now there are lots of CD and DVD. The sound effects are better than the tapes. However, CD music in windows can not be directly recognized, can not be directly copied to the hard disk (in other format windows can be realized, such as data file, VCD, DVD, but CD is not able to directly recognize). So, in order to put the songs on CD copied to the hard disk, you need special software to realize, this is called the track, there are a lot of software to achieve this function, the most common, we believe that the best is EAC (EAC.exe), this software, after ripping out music is retained in the hard disk in the form of wav in. 2, APE format compression when copy songs on CD to the hard disk (i.e. after ripping), the most original file (WAV) is usually very large, such as a CD music is about 700M, if it is separated into every song, every song that the size of the file in 20 - 60M. Such a large file that occupies the hard disk space, but also not suitable for online transmission. Therefore, you usually compress the original large file. There are a variety of the compression methods can be divided into two categories, one is the compression without loss, such as the use of monkeys (monkey.exe) this software can be achieved, it can put the original music file (WAV file) compression to the original size 50 - 60%, the file format is APE. Another type of compression is called lossy compression, with the advantage of compressing files smaller, such as 1 times more than ape files, and lossy compression in common form, MP3. But the disadvantage is that the quality of sound drops. Generally, the smaller the file is compressed, the worse the quality of the sound. 3, online deli
