👉 A "flacianist" is someone who is committed to preserving and promoting the use of FLAC (a proprietary audio file format) as a viable alternative to MP3, which has become widely used in digital music files. FLAC is a lossless compression method that allows for greater data transfer capacity without losing any quality of sound. This means that the FLAC format can be used to store and play various types of audio content, including MP3s, WMA, AAC, and other formats.
