FLAC stands for Free Lossless Audio Codec. It is similar to MP3, but lossless, meaning that audio is compressed in FLAC without any loss in quality: you get a perfect copy of your CD tracks, but with files significantly smaller than .Wavs.
This encoder allows to rip CD tracks to native FLAC 1.1.2 files using the Winamp 5 built-in CD ripper (free or pro editions). It offers 9 levels of compression, similarly to the reference command-line encoder.
More information about the FLAC format on the official project page http://flac.sourceforge.net/
Note: in order to automatically tag produced files, you will need a FLAC input plug-in with full media library support, such as mine.
