The latter ensures that rounding errors that may be introduced by multiple math operations disappear when bit depth is finally reduced again to 24 before entering the DAC. The magnitude of rounding errors depends on the type and number of operations done. I don't know the limits, but for what Fons calls "normal audio engineering practise" (see his posting above), 32 bit is enough. cheers, d _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
