FLAC stands for Free Lossless Audio Codec and, as the name suggests, it is a lossless compression audio format. Lossless formats are those that can reduce audio data in a way that is comparable to compression algorithms like ZIP or RAR lossless.

Advantages over these methods include optimization of audio data compression and therefore significantly better compression rates, direct playability on audio players, ability to add ReplayGain information and tags to files, as well as a wide support in many operating systems.

We want to draw the attention of users who are interested in archiving their collection and who do not have space problems, about this type of audio formats, since they represent the best solution for us to avoid uncertainties regarding the correct configuration or future security when using Avoid lossy codecs.
The possibility of always being able to restore the original bit, precisely by decompressing it, means that quality losses due to incorrect settings are excluded and a format change at a later time is also possible without loss and without re-copying the audio CD.
FLAC is now one of the best known and most popular codecs, as it is feature-rich and open source, free to use, and platform independent. FLAC is increasingly being used by audiophiles to archive CDs and distribute free music, and it is also enjoying increasing popularity among hardware manufacturers. The format has been a part of Xiph.org since early 2003, a project from which the lossy audio format Ogg Vorbis emerged.
Properties.
-no loss of quality, neither audible nor measurable
-very high encoding and decoding speed (test results)
-as part of Xiph.org, a free and open audio format
-Pauseless playback is of course supported
-Flexible volume adjustment using ReplayGain method
-very flexible labeling system
-Multi-platform software support (Windows, Linux, Mac OS X and others)
-Storage of up to eight audio channels (and therefore stereo, 5.1, 7.1)
-High resolution support (up to 32 bits and 655,350 Hz, that is, well beyond CD and DVD-Audio)
-Hardware players are available
-not patented, manufacturers do not pay license fees for its use

Recommended encoders and settings.
Download the FLAC encoder:
flac.exe 1.3.0 for Windows
libmmd.dll (possibly required file, copy to same folder)
The source of the encoder is rare goods. Binaries for other platforms can be found on the FLAC home page.
With FLAC, you only need to specify a compression level between -0 and -8. Lower levels result in faster compression, higher levels result in smaller file sizes. Experiment a little, which is the best compromise for you. Like the developer, we recommend the parameter -5, which is also the standard setting, that is, it does not need to be specified.
While the encoding speed slows down significantly at higher settings, the compression rate does not improve to a degree that warrants it. For example, the difference between levels 5 and 8 is usually a few hundred kilobytes, which is quite insignificant in relation to the size of the files. The subsequent decoding speed is not affected by the level of compression.
The original files are usually compressed between 40 and 75% of the original size. Bit rates generated for audio CDs are typically in the 700-1050kbps range, typical album sizes are 320-440MB. However, depending on the source material, the results may differ.
