I've always used 44.1 24 bit on all my projects and have a project I'd like to record at 48k 24 bit. I started a New project and chose 48k as the sampling rate. After it was opened I saw 48 24 on the transport. As soon as I record audio the transport changes to 44.1 24 and I checked the file created and it's 44.1 24 bit not 48k.
 
Under preferences I have the default sampling rate for new projects set at 44.1. I assume the New project dialog is supposed to override that default, if I set the rate at 48K, yet something isn't working right. Shouldn't this work?
 
I also wonder if it's because my AVB Ultralite is set at 44.1. I wonder if that the problem?
 
Any insight into what's happening?

In Sonar, change the default sample rate to what you want the the Motu AVB should record using using it,
 
Motu Says,  "When working with one MOTU AVB audio interface, changing the sample rate from within your Digital Audio Workstation will successfully change the sample rate of the hardware."
 
To set the sampling rate for new project:
Go to Edit > Preferences > Audio - Driver Settings and change the Sampling Rate field to the desired number. You can choose from the available options, or enter any number that your hardware supports.

Thanks for your insight on this. One would think that when creating a new project and setting the sampling rate  at 48k that it would override the Driver Settings Sampling Rate. Is this just a quirk with the AVB and some the sound cards or is this the way Sonar is supposed to work?
 
So here's the big question: If I do first set the Driver Settings Sampling Rate at 48 and then create a new project and choose 48k, will that project forever be recording at 48k, even if I change the Driver Settings Sampling Rate back to 44.1 where I prefer to leave it?

Yes once you set a sampling rate the project will always record on that sampling rate.
 
If I where you I would change the sampling rate of the AVB as well,before I open Sonar, cause I just purchased a Motu 624 and it`s giving me nightmares when fiddling with sampling rate.
 
Peace

 
Has anyone left the driver sampling rate at 44.1 and set the sampling rate in the File/New box to 48k and had that work? It seems to me that why Sonar has that setting in that box, so a user doesn't have to go to Preferences every time they want to start  new project with a different sampling rate. Or is this a bug?

What kind of nightmares are you referring to?

I did some testing and answered my own question. There is no bug. What happened is I started a project in 44.1 and created my own custom audio file folder for the wav files. I did some minor recording at 44.1, but nothing that I needed to keep.
 
When I realized I wanted to instead record at 48, I just created a new project file, but I kept the exact same audio file folder I had already created that had some 44.1 wav files in it. So in this case me choosing 48k in the new project box didn’t work.
 
The fix was to start a new project and this time name the audio file folder slightly different from the other one that had the 44.1 wav files. This time it worked great. I even went back to different 44.1 files and recorded in them and back to the 48k file and it didn't get confused.
 
So there's no need to worry with the driver sampling rate that is only setting the initial default sampling rate for the new project box. Its very easy to change 44.1 to 48, so all is well it works as expected.

The sample rate of audio files not referenced in the project do not affect the sample rate of the project.
 
How is the sample rate of a project set?
 
There are two ways to initialize the sample rate of a project:

1. The sample rate drop down in the New Project dialog or
2. The default in Preferences when not using the New Project Dialog

This is not the end of the story though and this is important...sample rate is not stored in the project file. The sample rate of a project may be changed at any time as long as the project does not reference any audio files. This means opening a project that does not reference any audio files causes the project to revert to the default sample rate regardless of the initial setting. Why? Because the sample rate is not stored in the project file. As previously mentioned the sample rates of audio files not referenced in the project do not matter. If they did it would have been impossible to have projects at different sample rates prior to per-project audio folders.
 
The sample rate of a project is set by the audio files referenced in the project. Until that time, the initial sample rate is used during the first session and the default is used in subsequent sessions.

I had a real snafu doing this. I had my MOTU (not blaming MOTU) set up for 44.1khz and the Sonar session was set to 96Khz. After the entire session of not noticing this, the project played back way too fast. Or the sampling rates were reversed, I don't recall. So, I had to go back and fix all this manually. There was a header tool I could use to fool Sonar into thinking a file was a different sampling rate so that when the session was opened, Sonar would treat it as the correct rate. It was a seriously confusing process. I don't recommend trying it. I recommend adding a step in the recording process to ensure the MOTU and Sonar sampling rates match perfectly. Otherwise, results might be iffy.

Meanwhile, the latest versions of Sonar seem to try and run at the rate of the MOTU, especially for playback. While I like this vs. the old error that would simply just not let you playback the audio, it does require additional diligence to just ensure your sampling rates are matched.

Thanks for all the details. I’m stil not totally clear on a few things. So in my case since I want to keep my Preferences / driver sampling rate default set to 44.1, if I want to create a new project and work at 48k for the whole project. I need to go to File/New and change the default sampling rate to 48k and then when the file opens. I need to right away record a little bit of audio to lock in the sampling rate for this song at 48k. Is that correct?

 
So if I then go back to some other songs and record at 44.1 and later come back to the 48k song, will I still be at 48k or do I have to go to preferences and change that default rate to 48k?
 
If import some 44.1 audio into this project, does that mess up my 48k sampling rate?
 
Thanks for your help,
