Unless you've fixed it in the last hour or so, it wasn't preclamping data to be dithered. I've written some code to do correct triangular dithering, but its untested. It builds OK, but I will have to rebuild the rest of ardour to test it, so it probably wont happen today. Patch attached, just incase it works ;) Paul, if you're happy with the code and you want shaped dither too, add a stub showing where the branch will be and I'l add that code too. - Steve ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ ardour-dev mailing list ardour-dev@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/ardour-dev
