Time shifting

I am sure this is a really basic thing.

I have recorded 2 separate tracks with a bass guitar.The first is slow and the second faster.

I want to combine them into the same project and I could not import the second .au file so instead I copied and pasted it into the project containing the first slower track. I copied it into a new audio track and now I want to time shift it so the two seem to merge seamlessly. When I use the time shift function however it appears to grab both tracks and shift them both around and I just want to shift the second track.What am I doing wrong?

You should not be messing with the AU files. Those are Audacity internal housekeeping files. and if you damage one, the associated show may not play.

You can open each project and cut and paste between them.

Attached is two Audacity instances running separate tracks (tone and noise). I selected the track in the background and copied it. Then in the front Audacity, I made a new blank track with Tracks > Add New.

Then paste into the new blank track. Then you can select each track and use whatever tools you wish.

How do I paste multiple tracks also how do I select just one track to time shift it

Are you using Windows? Which version?
Which version of Audacity are you using?

Have a look at Time Shifting for how to shift only one track when you want to retain a selection region in the other tracks.

If you have a selection region in the tracks and don’t mind losing the selection, just use F1, click in the track you want to shift to remove the selection region, F5 and shift.


I am using windows 8.1 and the latest version of Audacity.

Moved to the Windows board, thanks. When you give your Audacity version, please give all three numbers as per the pink panel at the top of this page. That avoids any possible confusion.

Is your problem with Time Shifting fixed, so this can be marked “[SOLVED]”?
