I'm slowly finding my way.
Sadly I'm not a mac person. using only wavelab here.
In wavelab, there are several options/boxes to check when doing a time stretch: "preserve pitch" is obvious, but I haven't dug in to find out what the "DIRAC processor" is.
Or whether or not I should check the "audio quantize" box and adjust the
rythym accuracy.
What I have found is working : leaving all those options unchecked and chopping the clip into smaller, roughly 45-1:30sec clips and stretching them each one at a time according to the other source.
I'm certain it isn't Healy's antics
and more of a warbly reel or an untuned nakamichi that's affected the source along the way.
Using the Oade source as a guide. Given it's a PCM recording and immune to analog mechanisms. I've been stretching the sbd, little by little - a piece a time.
If you want to see the shape of things, open up both Oade and sbd sources of Music never stopped. Out of the 4 tracks I've done now, this one is most warped.
Around 3:30 the sbd takes a big drag and starts to come back and forth around the 5-6 minute mark.
It's what led me to follow nuldogmas suggestions and use the smaller clips.
It's painful compared to the last matrix I made using 2 digital sources (jgb 11.9.91)
I'm hopeful that the set 2 pcm sbd will be forgiving and downhill from here.
I'd like to know what you all feel is a better listen, with +2db added to the Oade or without?
