FLAC

i prefer dbpoweramp, I know its not free but I just find it more convenient and user friendly. if anybody wants to give it a try http://www.dbpoweramp.com/ I have owned dbp since the ver 11 days(years ago) and have tried foobar2k and use to use EAC(eac isnt bad, but dbp’s built in ripper is a match for it and is easier to use to boot) flac is great for archiving files, I use vorbis for my music and audio books, with rockbox I pull 22-23hrs batt life when listening to audio books and music :smiley:
