i'm not sure what "all" means, but i don't think its remotely as clear cut as you insist: http://blog.bjornroche.com/2009/12/int-float-int-its-jungle-out-there.html moreover, its critically important to note that this issue arises primarily for float<=>16 bit int conversions, where generally dithering should be done anyway. the noise introduced by dithering will be at least on the same order of magnitude as the 0.005% error caused by different choices in the conversion factor. conversions to other bit depths don't face (precisely) the same issue. its great that you're absolutely convinced that your view of this is right. i generally have a lot of respect for your opinions. the problem is that there are 4 other people whose opinions i respect equally, and when i've discussed it with them, my only conclusion in aggregate has to be "it depends". --p _______________________________________________ Flac-dev mailing list Flac-dev@xiph.org http://lists.xiph.org/mailman/listinfo/flac-dev
