I am having a headache trying to align two sources that have different pitches at various points thru a song. The problem seems to be a fast-slow-slower-fast situation on one vs. the other. It is only on a track so far and conincides with the end of the cassette master (like towards the end of a 45min side). How does one align them properly without creating little gaps in one source? Does anyone wanna help me tackle the problem? I am trying to do the GD 12-15-1986 Jerry comeback show and have been struggling with the 'Let it Grow' for way too long. The results of my matrix from the rest of Set One has been really very nice and I believe this project is worthy of the work to create a matrix. Right now, I have only access to Wavelab 4c and am using the SBD as the time reference (and aligning my Audience master).
Thanks,
ANDY
If you want to stretch one file to match the other:
match up a precise start point and end point on each recording and divide the length of one segment by the length of the other (same section of music). You'll find that one is maybe 99.98454% of the other or something like that.
Use wavelab's stretch function (it's the only one I've tried that sounds good). Select the whole file to be shortened and do a time stretch with these settings
It's probably good to set wavelab temp files to 24 or 32 bit as well.
Note that there's no point in using anything other than the ratio box to set the stretch. All the other boxes only appear to be more precise - in fact they don't produce the stretch that they indicate. Rather, they always produce the nearest '3 decimal ratio', so it's better just to set it there so you can see the length of the the file you'll *actually* get. And 3 decimals is it - any more precision ends up getting ignored. "(thanks dklein)
