A duplicate post.

Doktor Avalanche
I think I resolved it although there are a few mysteries!

My project was set to 48/24.

I decided to select a single track and do Utilities -> Change Audio Format and change the new bit depth to "24" (I ticked dither). Then it behaved (more or less) normally again...!!!
 
This is strange - all the tracks got processed when I changed the Audio Format on a single track rather than just the one - can anybody confirm that this is this normal?
 
... and I still don't know what was going on before?
 
 
<resolved>
Now the situation has changed (which is much better but still not resolved)....
 
I often get just one single big click when playback commences like a power surge, when I move the timeline around during playback..  which maxes out the master bus. I don't know if there's a way to silence this apart from put in a limiter. I guess it's drivers/firmware but I'm definitely on the latest. I'll try disabling hyper-threading as well (although I don't see any evidence of it being the issue in task manager)... Any other ideas please let me know!
</resolved> = This was a plugin so it is resolved...
 
Does anybody have any comments to make about the above?
 
Thanks..

What was the recorded bit depth? What was the previous bit depth of the file you changed? 

Appeared to be the same John I checked it beforehand in the audio folder. The only thing I can think of is maybe something screwed up upgrading from x3... But wav should be independent?

OK I'm not understanding this. You didn't have a different bit depth of the recorded files. So why change it?
 
When recording in Sonar audio from a sound card it should be set to 24 bits.  You can later render at any bit depth you wish but you should record at 24 bits. This is the most any card can provide and will give the best results. 
 
If you record at 16 bits you need to record hot without clipping. 24 bits lets you record a lower audio signal with no noise. Its much easier. 

Exactly ! Why would I! And yet somehow this stopped the crackles..! I worked out there had to be some reason why groove clips were working fine which led me to try it... (check the original post for symptoms).

I was always on 24 before and after (check the post you quoted).

Maybe it clears up some metadata or something by resampling at the same bitrate? Whatever it is it's extremely weird.

The fact that 'bounce to clips' did nothing either???

We seem to be going around in circles. If you are recording at 24 bits there is no reason to change it. Sometimes crackling is due to an overload of a plugin. Sonar itself wont clip with either the 32 bit FP audio or 64 bit audio engine. Yet some few plugins can't handle an overload. This is really a clipping problem of a plugin. 
 
At present I don't know the cause of your crackling.  Check any and all plugins to see if its getting hammered. A quick way to check is lower all the levels on all your tracks. See what what happens. 

Nope John...

This was always a weird issue whereby groove clips wouldn't crackle and bounced clips would.
It is not a plugin issue (I tested this by disabling all plugins).

This was fully resolved by resampling from 24bit WAV to 24 bit WAV. . this definately cleared up the issue. (As I said the issue is resolved I just have mysteries to learn from).

Yes it is weird. I guess we put it down to project glitch and nobody has ever seen this?

Also all the tracks got processed when I changed the Audio Format on a single track - can you or anybody confirm that this is this normal?


Thankyou...

The resampling is curious. Are there actual duplicates in the audio folder though? If so can check them for differences, but I have never actually used that process before. There should be two files for each if modified in any way.

Now that's interesting. I checked it with a backup. If there are two wavs maybe I compared the wrong ones, I assumed there would only be one... I'll check tomorrow thanks
