dear ragards.

You may have imported files with different sample rates.

The Project Rate is shown in the lower-left of the Audacity window and assuming you didn’t change it, it should match the 1st file opened/imported. (That will be the sample rate for the exported file.)

The Tracks menu has a Resample option so you can make them match.

Thabk you ill try tommorow and say if it works.

thank you man it worked love u
