Those to-be-eliminated 8 LSBits (bits 17 - 24) have an influence on the resultant 16 MSBits (bits 1 - 16) when dithering. Therefore, the truncation can only happen after the dithering has taken place. Or I'll put in another way: If what you say is true, then any truncated piece of audio can be magically dithered after the fact? Obviously not. f-erenc szabo, smarty pants (Tastes awful, but it works) Z+E+R+O+B+E+A+T "NOW POWERED BY THE MIRACLE OF THE TRANSISTOR!"
