>heya< >> Do I need to have a 24-bit soundcard to do play these files at >>all? Is logic unable to use 24 bit files in a 16 bit mixer? >yes of course !! you need a 24 bit capable card , min. AM3 !!!! No! You only need a 24 capable card if you want to use all 24 bits. You may play back 16 and 24 bit files together using only a 16 bit hardware (only upper 16 bit will be used).
