hi,
i don't know whether you still need the answer, i used Bigasoft Audio Converter too but in fact, this program extract audio is not good. When I upgraded, whenever I converted FLAC to ALAC, it would prompt me to fail to switch, I consulted their logistics department, but could not give me a definite solution, and then I used another converter,http://www.videoconverterfactory.com/tips/flac-to-alac.html the fact Proved that it really can finish FLAC conversion success and as long as not to change the bit rate, the sound quality will not be damaged
