and is also a healthy demonstration why bit exact is not truly
necessry, just mean squared error (or something like that) .
The other thing that needs to be tested is backward compatibility
with previous versions for again, MSE.

good work
1 LSB can come from anywhere.
usually truncation bias.

you might want to oversample it say 4x inside the PC before the

Hi,
If the goal is to identify regressions, comparing the previously generated
output data to the output of the changed code is sufficient. And for this we
can simply compare the value by value difference since beside rounding errors
the output should be very close. For that a simple value by v
My video compression work tells me we almost need something else rather
than a bit for bit compares.
something like a SN or difference merit
Anyone familiar with video compression will understand this concept .
We would do an encode- decode and then look at the RMS, peak, and
various other sta
