Implement AtAAK! - Vocalign/Melodyne-like audio alignment

Yes! This should also work with instruments, like doubled guitars or horn sections!

Sounds useful :) EDIT: went to vote and realised I already had! ;)

Is there any software currently which has this implemented ? (to check it out in action)

implemented 

Is not that already implemented in the Reaper? I mean "match on/off" option in file browser

Something like this could possibly be cooked up with ReaScript and stretch markers. I'm already doing this manually a lot, but a more automated workflow, along with an improved transient detection algorithm (!), would make life a lot easier.

Some kind of automation script would be a godsend. I am processing a lot of dual guitars and this would be very welcome :D

look the great spk77 script here

Thanks for the link! A useful script no doubt, but it doesn't tackle the problem exactly.

What's also nice is that Ataak! seems to work with polyphonic material, whereas Reavoice Pro for example only works with monophonic sources. - Aligning acoutstic guitar takes, anyone?
