A regular file in FLAQ is up to 6 times bigger than a regular file in Mp3. FLAQs, however, are probably half the size of CDs but can have just as good boosts in the quality of audio. Also, you can get quite a few types of FLAQs. You may get the 16-bit CD quality or the even better 24-bit-192kHZ version which will give you an even better quality. It is also better from another aspect. Even for transporting files, it reduces the downloading time to less than half.
