SOLVED: Interesting and weird issue

Just recently (last two days) when I open CWP projects (with audio saved with the project) Sonar is pitching the audio a semi tone lower. Shut down Sonar and re-open problem goes away for one project. Open a new one and the issue comes back??
 
These are all finished projects I am simply re-visiting to make minor tweaks to.
 
It is really weird, and no the clips are not groove-looped, nor are any there any pitch affecting VST's in the projects either .
 
Anyone else experiencing this?

Yeah it could be, but these have had no issues with SR mismatch previously - but I will check it using some test files and the Sonar import SR conversion algorithm.
 
Thanks for the suggestion

Sounds like the difference between the project being recorded at 48Khz sampling, saved. Then, the default sample rate for Sonar is later set to 44.1Khz. After that, reopening the CWP project, but somehow, Sonar keeps it in the new default sample-rate.
 
In preferences, under (Advanced) Clock, you may check to see that the Clock source is set to Audio.
 
Otherwise, I don't know why a simple restart fixes the issue. That's a little weird.

When this happened to me it was when ever I played a song in Windows Media Player then return to Sonar it would have changed the rate. It was the share drivers option that fixed it for me.
And I believe that going from 44.1 to 48 results in a slow down? 

Thanks guys - good words! From the above I have sussed it out I think. I usually leave everything at 48k but these projects were originally audio tracks created in another app at 44, and that indeed was the problem.
 
As an interesting aside in reply to Cactus - yep the same thing happens here - I finish up a project, create the MP3 backing track to the data folder for same (bearing in mind Sonar MP3 maker only allows 44.1/16bit conversions), and then play it using WMP to check for pops and crackles at the start. Then when I return to Sonar and load another project the pitch shift happens. I suspect that a reload of Sonar works as it is restoring all my Sonar boot-up preferences...
 
 
 
 

It's interesting to see when people record at 48Khz vs. say 96 or 192. I think the higher sampling rates are over-rate-d sometimes. Some people claim to hear a huge difference between 48 and 192, but the real truth is, it depends on what you're listening for and through what. Sometimes it's not the sampling rate, but how the A/D or D/A converts them. My old Yamaha is amazing at it's maximum sampling rate of 48Khz, where my MOTU is at its best at 96Khz. One (unnamed) A/D converter manufacturer exposed that, even though a converter may support 192khz, it may actually designed to best perform at 96Khz. 192khz was typically a marketing ploy.
Personally, I can hear a much bigger difference in converters and moving from 16-nit to 24-bit than I can from 48Khz to 192Khz sampling.
 
Nine Inch Nails is releasing an Audiophile recording soon at 24-Bit 48Khz....interesting aye?
