The ?? mean that jdelay doesn't trust the signal. This is confirmed
by the frequent polarity inversions - jdelay tries to find out
which of the two polarities is correct and can't decide.
The reason could be either insufficient level (unlikely, as jdelay
can work with very noisy signals), or a frequency-dependent delay.
Jdelay uses phase measurements of a number of tones. The ?? mean
that the results are in contradiction. Try to verify the signal
path.
I'll try again with a proper setup! I've used a [left]-sennheiser
headphone-speaker, and thinkpad's build-in mic ; and a Neumann Tube with
the UA25.
I missed the start of this thread, so I don't know what exactly you
want to do... If it's measuring the latency of you soundcard, just
cocnnect line out to line in !
anyway, I remember playing with a non '??'
jdelay - around last summer.
can that be? maybe it was aliki. how old is jdelay ? ;)
Several years now I think...
Aliki is something completely different (but you use to it measure
latency as well).
