什么是 FLAC 文件？
无损音频压缩——以一半的体积保留 CD 品质
Free Lossless Audio Codec file (FLAC) is an audio format similar to MP3, but lossless. What does this mean? The audio in a FLAC file is compressed without any loss in quality, whereas a MP3 file compresses the audio but usually lowers the quality of the file by excluding certain frequencies. A FLAC file works similar to how a ZIP file is compressed. Since FLAC is highly optimized for audio, you’ll receive a better compression ratio when compared to the ZIP compression algorithms. You can play compressed FLAC files in your favorite media player (including VLC, your car, or home stereo, or computer) just like you would an MP3 file (without having to uncompress it separately).
FLAC files are one of the fastest and most widely supported lossless audio codecs and is one of the few that are non-proprietary and has a well-documented open-source reference implementation. There are no attached patents for FLAC files. It was developed in 2000 and FLAC files discourage developers to not include any DRM features.

谁会使用 FLAC 文件？
口述历史工作者、大学和图书馆的数字化团队以及实地研究人员,依赖 FLAC 将采访和录音保存为存档母带,因为压缩后的文件解码后与原始文件逐位完全相同。播客制作人、广播工程师和母带工作室也会保留剧集和素材的 FLAC 版本,以便日后重新编辑或重新导出而不会有世代质量损失。
FLAC 与 WAV：应该选择哪一个？
FLAC 和 WAV 都是无损格式,但 WAV 以无压缩方式存储音频,而 FLAC 将其压缩到约为原来一半到三分之二的大小,且不改变解码后的音频。FLAC 还内置元数据标签和逐帧校验和以验证文件完整性,而 WAV 基本缺乏这些功能。在期望原始 PCM 的录音和编辑软件中工作时选择 WAV;对于长期存档、分发或希望以更小文件节省存储和传输时间的上传,则选择 FLAC。
