It ooccured to me that its not thedownsamling thats the problem (it does 15->12 fine after all) but it seems to be the fact that the destination type is shorted than the source type. So maybe I should make everything down sample to 12 bit, but store the 12 bits in a 32 bit word rather than a 16 bit word ? Mind you, if dithering isnt a significantly slow operation under Mac OS X then I might just go for 32 bit all the time maybe... -bat. _______________________________________________ Xmame mailing list [EMAIL PROTECTED] http://toybox.twisted.org.uk/mailman/listinfo/xmame
