Sample rate conversion
My system is set up running at 48kHz and I want to import a project that was done at 44.1kHz. Is it possible to convert the imported project to 48kHz? I've imported projects before and Sonar resets it self to the rate of the incoming project - but I would like it to stay at 48kHz.

Bitflipper turned me on to this when I was trying to figure a project out that involved the need for rate conversion. Worked great - also does batch conversion if you have a whole folder of files to work on: http://www.voxengo.com/product/r8brain/ RB

R8Brain can only convert the sample rate of the raw audio files outside of SONAR. The challenge is to get the internal sample rate of the project file changed, which can only be done if it contains no audio.
So what you'd have to do is this (working with a copy of the project, using per-project audio files, of course):
1. Set SONAR's default rate for new projects to 44.1kHz.
2. Open the 44.1kHz project, and delete all the clips in the project, which will disassociate them from the project without losing the stored audio files.
3. Change the default rate back to 48kHz, and the stripped project will change with it since it contains no audio to prevent that.
4. Import the 44.1kHz files back into the project, track by track, and SONAR will do the sample rate conversion.
The challenge to this is if the clips don't all start at 00:00:00:00, and/or if there are a lot of them, making it difficult to know which audio files go with which tracks.
If the project is already at a high level of complexity in terms of content and routing, I would probably just run it at the rate it was recorded, and be done with it.

OK brundlefly - I understand what you're saying. I'll give it a try and if it complicates things too much I'll stay with the original sample rate. Thanks

Thanks, Brundle, for the excellent advice to RuffRider.
When I used r8brain, I needed some tracks produced in Sonar to be compatible with a video editing program. For that purpose it was ideal, and performed perfectly.
But once you pointed out that r8brain wouldn't actually do for RuffRider's problem - I realized I hadn't thought that situation through all the way.
RuffRider, that little app from Voxengo, r8brain, is still a useful app to grab for possible future use.

Isn't there a way to export each clip and it retain it's location? Or, would not exporting fill in all the blank spaces and then lining them up would not be a problem?

You can export the files as Broadcast Wav files. They will be time-stamped and should load in the correct locations.

Sidroe, so are you saying that the files should be exported out out SONAR as Broadcast Wave files after they have been imported into SONAR?...

Instead of importing them as they were in your old project into your new one, export them from your old project as "broadcast wav" files. Then import them into your new project.

Instead of importing them as they were in your old project into your new one, export them from your old project as "broadcast wav" files. Then import them into your new project. Yes, that solves the problem of re-importing clips to the correct position if they don't start at 00:00:00:00.
