同样的文件，ALAC 比 FLAC 体积要大一点，ALAC 的效果更好吗
效果一致，都是无损。

引用自Head-Fi.org - Headphone forums and reviews for audiophiles论坛：原帖地址：FLAC vs Apple LossLess建议点过去看完整讨论，以及联动贴ALAC vs. FLACHenry FlowerAnyone who tells you that there\u0026#39;s an audible difference between ALAC (not AAC) and FLAC is a total ignoramus or has a broken computer; that\u0026#39;s putting it as politely as possible.
tho2468FLAC and ALAC are both lossless, therefor there is no difference in sound quality. There is a great article about this on FLAC\u0026#39;s Sourceforge site,FLAC - comparisonWhat matters when considering which to use? Encoding speed, usability, and to a lesser extent decoding speed. The kicker for me is how SLOW the Apple ALAC encoding is, slowest of ALL the codecs compared there. However, Apple has made ALAC open source now , so there may well be improvements coming.The Sansa Clip Zip, among other players, supports FLAC. It does not support Apple\u0026#39;s lossless AAC files (codec=ALAC, file extension=m4a).I expect the Apple devices do not support FLAC (or any of the other lossless codecs).Gordon Rankin:
【同样的文件，ALAC 比 FLAC 体积要大一点，ALAC 的效果更好吗】 4. File formats. Any reason why a .wav, AIFF, or FLAC file is better than say Apple Lossless? Again people suggest a strong preference for one over the others, so something must be going on here?
Files that are compressed like FLAC and Apple Lossless never sound as good as .wav or AIFF. But it\u0026#39;s best to use AIFF as the Meta data is stored in the file and therefore if you lose the hard drive the backup files will be easy to recover. If you have .wav files and loose the drive... good luck you might as well start over.
We have seen the compressed file syndrome on slower computers. The faster they are the harder it is to tell the difference between say an AIFF and Apple Lossless.

ALAC / FLAC / APE 这些无损格式都是把 WAV 无损压缩了而已，原始 WAV 文件相同，这些格式音质也都没区别，除非解码器问题。举个例子，你的 .docx 文档用 zip 和 7z 压缩，7z 压缩率更高文件更小，但你的文件本质上没有任何损失或变化。

你别听他们瞎说 虽然都是无损但是音质还是很大不同的 ALAC的音质更接近WAV 声音听起来更有弹性 而FLAC则音质偏干硬 如果你不信的话可以自己找一首歌曲的ALAC和FLAC版本自己体会一下。

既然是无损格式的，只要能保证来源，那音乐本身的质量都是一样的，不管格式是ape/flac/alac/wav还是其他

差异可能不是音频文件的差异，可能是它本身支持封面，ID3信息等，带来的其他体积增加。也有可能是它本身的压缩算法，最终生成的文件跟FLAC不同。但是个人觉得用同种设备听不出差别。
