I try to install Rubberband as a LADSPA plugin but after I do not find traces of it in Rosegarden, Ardour, Audacity.
I will do other tests.

audacity can change the pitch/tempo of any audio clip in any format.
But Audacity manages the "tempo"?
Then perhaps it would be better Ardour?
Among other things, I also have to be able to handle it from Rosegarden and I do not think Audacity handles synchronization with Jack.

Perhaps, from what I read on the Internet, the only way to handle the track is to use Ardour via Jack synchronized with Rosegarden.

What do you think?

Rubberband is also meant to be able to do this.

You can find a ladspa plugin as well as a cli version for it, which means, I guess as I've never played with it myself, that you can fiddle with this stuff in Rosegarden.

 I found a copy in the unbuntu repositories. But the web site is http://www.breakfastquay.com/rubberband/

Doesn't Chris Cannam have something to do with this? If so, maybe Rosegarden could interact with rubberband in more sophisticated way than I am suggesting.

I just read your message now.

No.  You might try the sox toolkit, which can do that.
