Recently got to work on a film project which required me to switch my sample rate (SR) from 44.1K to 48K. I also had to use a different DAW. When I returned to Sonar this seemed to wreck all kinds of havoc (okay controlled chaos) with Sonar, particularly existing items (projects and templates).
 
I'm not sure if there is any inherent advantage to 48K SR although clearly if I were to continue getting film work there seems a requirement there...and, oddly, the anal retentive in me somehow regards 48K as more mathmatically cohesive with a 24bit bit depth (which I always use). Yes I know that's silly...
 
So here's my question: if you need to work on 48K projects do you adjust the SR on your soundcard before opening projects (i.e. going back and forth between 44.1 and 48) or do you just do everything at 48K. Bear in mind that I have lots of templates - some of which cause a white screen crash during instantiation (Scuffham S-Gear seems to be a particular culprit).
 
Thanks,
 

In my case it depends on the audio interface. My Edirol UA 101 requires a shutdown before I can change the sample rate. Not so for my M Audio stuff. If I'm opening a project and using the Edirol I have to change the sample rate before opening SONAR.

I'd stick with one sample rate for simplicity. SONAR's sample rate conversion is excellent, so you won't notice any degradation if you record at 48KHz and have to convert to 44.1 for the occasional CD.

If you use a lot of samples, 44.1 might make more sense because most sample libraries are 44.1. But if most of your projects are straight audio and you do a lot of DVD audio, then 48KHz makes more sense.

bitflipper: Just curious, if I am at 48K and I pull in some 44.1K samples for a track does the sound card just fill in the extra bits with 0s?

Definitely leaning towards the simplicity thing...I just wonder how many templates I have that might need to be redone - and if I should just bite the bullet (so to speak) and rebuild those templates.

Thanks to both of you for the input.

Regards,

If you import them at any sample rate, it should work just fine.

I never knew you could change the sample rate of a project. That would have been useful info a few weeks ago. LOL! Where's that manual. ;-)

As rule of thumb, most TV and film requires your audio delivered in 48/24 (industry standard). Just set up Sonar using this as the default setting. If you dump in audio that was recorded at 44.1 (loops, etc), shouldn't be a problem.

BTW if you're working at 48, try recording at 96 if your soundcard allows.

Correct... importing loops with different sample rates won't cause a problem. SONAR will just convert them to the project rate.

Something I'd not given any thought to before: SRC for sample libraries. Obviously, SONAR needs to convert a 44.1 sample library to 48 if your project's at 48. Not a big deal. But what if you're not rendering/importing audio, just playing back MIDI-driven samples? Would that not require constant and continuous SRC every time you hit the spacebar? 

With Dimension Pro and SD3 samples now as 44,1 flac files,
there has to be a first conversion to wav and then a second conversion to 48.

It would be interesting to know how the various conversions are handled on the fly.
