sample rate does not match sample rate of session

[tamaram33436970]

Hi everyone, I'm new to Adobe Audition.

I currently got seven multitrack sessions of different audio recordings I've already cut, edited and categorized.

Now I wanted to put some snippets of them in another multitrack together. Turns out (since I got the recordings from different people) some of them are 48 kHz and others are 44.1 kHz.  So when I try to copy and paste a clip in the new multitrack session with another sample rate, I get the error message “the sample rate of one or more clips does not match the sample rate of the session. These clips will not be inserted." 

So my question is, how can i put clips with different sample rates together in a multitrack session?

I know I should have fixed this before editing, but is there a way to convert them without doing the editing-work all over again?

Thank you for your help

Tamara

This is happening because you are doing a copy and paste, and there is no actual file, as such, to insert from - just the clipboard. But if in the original session you turn each clip you want to copy into a unique copy (right-click on the selected clip for the option) and save it separately, then when you go to insert it into another session you will get a slightly different notice:

If you click on Okay, this will automatically create a copy of the clip at the session's sample rate for use in it. When you close the session, you will be prompted to save this new file. If you don't save it, it will remain in the session file list but you will have to re-convert it next time you open the session.
