Change Tempo to half time without stretching wav audio?

Hey,
i have been around for awhile using Sonar for a long time.
 
i have some ancient tracks that were recorded (example) at tempo 150 and want to copy - past into new project at say tempo 75
when i attempt this- the paste gets stretched out oooooooof timmmmmmmmmmmme kinda like its hangin onto broadcast time stamp or something.
 
i have tried everything i could think of short of exporting and re importing (export audio menu) this i wish to avoid as i have a lot of edits in play.
 
IE copy track in one project - Paste into new project with new tempo - overrride the timestamp by using beginning of song as reference point of start.
 
if i bounce it all out and back i lose all my edits and automation is a do over -- time waster --posiible degredation of audio
 
anyone got the secret sauce ?
 
thanks
 
 
EOE
 
 

Is this a bit-rate issue?  Check to see if both projects are operating at the same bit-rate.

Audio snap does this and its a snap. No pun intended. Yuo can change single files or whole projects in just a couple of clicks. Hey, i may try out to be the new Billy Mays...

audiosnap?

for 50 tracks ?

hmmm

got a link to that video CJ?

time is cut exactly in half

It's still not clear to me whether you want the audio to change tempo, or to retain its original tempo. When you lower the tempo of a project (or copy audio to a new project with a lower tempo) with the clip set to Follow Project (Autostretch enabled), the playback time will double , not halve. And if you lower  the tempo without stretching the audio, the audio will occupy half as many measures in the timeline, but play back at the original rate. Which of these two options do you want? Or do you want something else?

C J) stretching it to the song tempo sounds good - but i want to keep it as virgin as possible by changing the project and not the audio.

Um if you change the tempo, the audio changes also. There is no way around this. Do a save as to keep the project as vergin, as you callit and then youll have a unsnpped version.
And yes, AS works great for this.. The interface is easier than the old one. yuo just need to get used to it and learn it. Im much faster with the new audio snap

i have experimented at length

the pasted tracks will not remain in context (they are edited bits and pieces) not (bounced to clips)
contiguous -- they get stretched out and track names are lost too - lame

i will not alter the native wav files as they are great tracks that may suffer from time pitch alogs

i want to do this (the right way) with the app - not the audio

thanks to all for the input - no solid answer yet

Hi there,
Just a thought.  Forgive me if it's not thought out.........
Get yer project dialed in at the new tempo, ditch the audio, go to the old project and export audio into wave files and import into new project.
Should only take a few days.......

The non-contiguousness can be and probably is a source of problems. Audio Snap doesn't see empty space, or adjust for the changed context of the clips.  

It's still not entirely clear to me what you're trying to do, but it sounds like you're trying to do it very much mid-project, with lots of non-consolidated clips and empty space, as opposed to eg stems that all start at zero and end at whatever. If that's the case, then I believe your patience will snap long before Audio Snap gives you a satisfactory full project bpm shift.
