Hey
hey,
it's easier to describe the problem I think.
I hae two pieces, one the song with vocals, the other the exact
same song, but only the instrumental. Now I'd love to isolate the
voice by alligning them and mixing them with one having inverted
phase. Since I can't see, and apparently often instrumentals don't
start at exactly the same time, I need a way to synchronise those
tracks. time shifting by hand is very tedious and hasn't yet
yielded a perfect result. There are other issues, which can cause
"confusion", so I'd like to get this one out of the way.
Does anyone know of a way to do it from the commandline? Sometimes
alligning the beginnen of a piece (the onset of sound) might do,
but sometimes it's a little more complicated. Anything from Sox to
Csound will do. :)
I appreciate any hint in the right direction! Thank you!

sorry f, meant to send to list:
you could assign a midi controller (knob, fader, etc) to a delay
time parameter.
maybe something like this in ecasound(except with delay):
http://ecasound.seul.org/ecasound/Documentation/examples.html#midi-io
you may be able to specify the parameter range and possibly assign 2
controllers (
for coarse/fine) to the delay time parameter so you could "shuttle"
the delay time in real time by ear. i've done something like this
before except with eq filters but its been while. i'll see if i can
find what i did.
