FLAC stands for Free Lossless Audio Codec, meaning that the music format compresses data loss at a low level.
The popularity of FLAC has contributed significantly to the lack of DRM (Digital Rights Management), leading to the sharing of FLAC among extremely easy players.
DRM can simply understand digital rights management, intellectual property rights. Because of this, Apple must create its own format, similar to FLAC, but named it ALAC (Apple Lossless Audio Codec).
First introduced in 2001, FLAC quickly became popular by open source, and other competitors all had big drawbacks,
ALAC attached to Apple devices, and WAV was too big. The size of the devices at that time was quite small, and could not save the meta tag.
