[Vorbis] flac in xiphqt seemengly behaves incorrectly playing 24bit files
Hello, upon installing flac1.2.1 and xiphqt0.1.9 component on a mac, 24bit flac files, whose integrity has been proven and which otherwise decode and reproduce flawlessly, play in quicktime player with wrong volume, i.e exactly 2^8 = 256 times too loud. I guess, the appropriate amplitude scaling routine might have been accidentally omitted somewhere in the code. In case this issue goes beyond your concern, please be so kind to report the problem to whomever it may concern. Hardware: MBP OS: 10.5.6 QT: 7.6 (472) Pro FLAC: 1.2.1 XiphQT.component: 0.1.9 Thanks in advance, Regards, SJ

Thanks for reporting the problem! I don't have an immediate answer but hopefully Arek or another of the XiphQT devs will see it soon. Monty
