DM780 samples at 8kHz and has a lot of encoder / decoder code in common with fldigi. MT63 / Olivia having being taken from Pavel's original code.
I'll try to find the Microsoft Blog entries which explain why some rates such as 11,025Hz are so poor with W2K / XP but not with VISTA. It's not a compromise - anyway with luck I'll find this explanation this morning. FWIW I generate 8kHz from 48kHz sampling using Moe's code.

Thus comparisons run on the same PC may not accurately reflect each application's performance in isolation.
