Summary	0000711: Shaped dither on export of region creates noise
Description	I have final audio tracks in Ardour. I tried right clicking the waveform and doing an export from the menu. I did it three times trying out all three dither types. Rectangular and triangular are both quiet in my lead-in while shaped dither creates an obvious nasal noise in the background. I have not tried this from the session menu.
Additional Information	Ardour/GTK 0.531.1 running with libardour 0.830.0 from a tarball taken at 2PM PST Friday, 9/9/04. Machine is Gentoo gentoo-dev-sources 2.6.8-gentoo-r2, gcc-3.3.4, glibc-2.3.3-20040420-r1, alsa-1.0.6a

v2 2005-11-01 11:24 developer ~0002372	This problem was traced to a problem in the shaped dither algorithm from libgdither. libgdither was fixed and the fix was incorporated into ardour.
