Anyway, clicking on http://www.futurlec.com/Others/CS8412.shtml and reading the PDF file, one can see on page 5: " 6) Q: How do I determine the delay through sample rate converter ? a: The group delay (tgd) through the SRC is 41/Fsi + 43/Fso " - so these are the two real indicators of sample rate conversion quality. Actually, I think the first item: 41/Fsi. This is because these numbers reflect the well known sync interpolation implementation and reflect its precision, i.e. sample rate conversion quality. In software one can choose these parameters him/herself, so even better quality (if desired) can be achieved. The rest is wishful thinking.
