Change audio sample rate after creating project?
I accidentally created a project with 32kHz audio. Since it’s DV in and DVD out and a choral performance I’d rather not conform the audio twice. But the sample rate selection remains greyed and disabled no matter what I try.
Lacking better guidance I’ll finish up the video and export it to avi, start a project with the correct sample rate, and marry the edited video with the original sound. There’s no work invested there beyond a fade or two.

When you export to AVI you will be using inferior audio. Since audio is a bog part of what you are creating, I highly suggest that you close Premiere Pro, delete the conformed audio files, import the project into a 48KHz prohject, and let the conforming begin.

Sorry I wasn’t clear. Starting over throws away significant effort that’s been put into the video so I’ll finish the video editing and export to avi. Then I’ll use that avi (edited video, 32khz sound) in a new project, but replace its sound by importing the original 48khz source. The audio doesn’t require much work so the replacement is easy.
I’d hoped there was a secret switch in Premiere that enabled audio-rate selection in an active project. The edit box is there, tantalizingly greyed out, suggesting that since it’s there, there *must* be a way. I wonder why they do that?

You won’t have to start over. Follow Steven’s advice and import this project into a blank one set up with 48k audio.
If you are short of disk space, then delete the old audio conform files first, since a new set will be created at 48k.

When you import a project at 32KHz into a project at 48KHz, the sequences are all in a bin under the name of the old project. No starting over. Just new settings. Try it out. You will see.

On your system does it actually import the entire project, including its state (effects being applied, temporal alignment of clips, etc)? I tried it again on mine (XP Pro SP2) and the project files are certainly there as you say, but nothing else. No effects, no alignment. Must be a button I need to press.

Okay, I don’t pretend to be expert at this so it may in fact be possible to “import” a project into another one, along with its work-in-progress state. What worked here was to open the 32khz project, highlight the timeline, click Edit/Select All/ Copy, close that project, open the blank 48kHz project, highlight the timeline again, click edit/paste. Premiere has nicely populated the files window with all the files, and the timeline with all the clips, and all the edits are there. I don’t know if there’s a trap awaiting me – I suppose I’d better try a render/encode before spending much labor on editing – but for the moment it looks just like the project I left behind, except still says it’s 48khz.

Copy/Paste should work, but you should have been able to see the same sequences in the imported bins when you imported the old project.
