Tempo question

I'm kind'a new at this, but

i have a question.

so i recorded the intro to a song. its a very nice, long intro, it has 3 tracks of strings, and 2 tracks of cool recorded effects,
and it was recorded at tempo 70!
(note we are talking about wave recordings and not midi)

i know how to change the tempo, and even change the tempo of the wave files.
but what i want to do is, slowly increase the tempo over a period of one minute!

i want it to start at 65 after 40 secondes go to 68 after another 20 seconds go to 72 and so on...

and i want it to transform the recordings so that tempo at that time only.

am i making myself clear?

Yoav out!

If you have only audio tracks, then changing the tempo setting in Sonar makes no difference.

If you are using Sonar 4, then you can do some time stretching/compressing. Look up "time stretching" in the help or see it discussed starting on page 395 in the Sonar 4 manual. The idea behind time stretching is that it's like speeding up or slowing down a vinyl record WITHOUT changing the pitch. It works pretty well (as long as you don't change the speed too much), but it's not yet perfect technology.

If you're running Sonar 3 or earlier, then there's no way to do the time stretching natively in Sonar. There are plugins and external signal processors you can use, but I have nothing to recommend; I'm totally a MIDI composer.

hey yoe .. as you see guys here usually read just some of the first lines ( the GIRLS do read everything ;)
so no wonder you get such answers.. i wonder if at least now they would read what was your REAL request (above)


jphilpit got it right ! - i must add .. you should work each time on a selected region of a few measures (even one measure at a time..depends how FINE you need the tempo to go up over time) and then use time stretching to bring the tempo up gradually ...each selection would have just one tempo so that's why you got to split it and work in smaller selections.

Sonar 3 and before - you MIGHT have the older time/pitch audio fx from older versions (if you had them) or maybe these are on the cd's as an optional installation ( can't remember what was the case with each of the versions)
















I KNOW..... I KNOW............ i knowww

talkin about MIDI , man ? or maybe audio ? hmmm

Which Version of Sonar ? ( like this even matters that much..)

blah blahhh
