FLAC is a ‘lossless’ format that provides sound fidelity equal to the original master tape. It is also “open source” so that the file will never be altered technologically by the owner so it is rendered unplayable. We have an extensive explanation about FLAC specs here:
The most important thing we want you to know about buying FLAC from Passionato is that you need a special player for FLAC, or you need to convert the files so that they can be played on your existing player. For PC based customers, we strongly recommend the MediaMonkey player, and for Mac customers, we strongly recommend reading our blog post entitled “FLAC on a Mac”.
