"With Capstan there is now for the first time a program capable of

wow and flutter from musical recordings - whether on tape, compact
cassette,
wax, shellac or vinyl. Capstan detects wow and flutter by analyzing the
musical material itself, so the medium is of no relevance. In this,
Capstan
is clearly superior to solutions such as bias tracking, because Capstan
still works even if the tape has already been copied several times or
digitized only in low resolution."
I'm curious as to how Capstan distinguishes between flutter and vibrato --
or simply the fact that even a note played without intentional vibrato might
not have a steady pitch.
The user does it. There are a bunch of settings that have to be adjusted on
the fly, and even so it is a fine line between sucking the life out of music
and cleaning it. The overall effect is useful for severely damaged recordings
but even so it's still a slow and painstaking process.
Think of it sort of like Autotune... you can do it judiciously and you can
do it well, or you can do it without thought and make things sound awful.
and here's an example of why I'm so insistent on defining "science" as the
process of asking the right questions. These are my "right questions" about
Capstan -- Has anyone ever applied it to a purely digital recording? If so,
what happened?
I did not, but you can adjust it to that it does nothing. Likewise you can
adjust it so everything sounds like the Academy of Ancient Music. It's
a sword with two edges.
