Pops and crackles + 99db

Hello,

I've been having this problem where the multi-out tracks from Superior Drummer peaking, showing a value of 99db.
This occurs when I mute or unmute tracks while the song is playing OR during bouncing/mixdown. It happens very frequently during mix down and bouncing tracks.

So the exported tracks end up in silence with occasional pops and crackles within the track itself.

I'm using x64 Windows 7 PRO, with x64 Sonar x1 build 255, SD2.2.3 (if i remember correctly) 64 bit version.

Would be great if someone can help me out with this

I'm using a Presonus Firebox firewire interface, with 8gb of RAM.
My PC is pretty decent and new, an i7 2600k (quadcore) running at 4.0ghz.

After the pops and peaking occurs, I have to close the reopen the project again before I can continue working on it.

I'll try out the buffer thing and I'll post my results here.

sorry for the late reply have been busy of late but have tried the above suggestions without success.

I've noticed that it is very likely to occur if I were to un-bypass all effects and pressing play after that.

I have several plugins within the SD mixer and I'm also using the multi out too.

I just had this same issue develope for no reason on an Audio Track.  The project only has about a dozen tracks but it only hit one of the tracks in the project.  It just started for no apparent reason.  Meters peak and that wonderful noise that is intermittent through out the track.  Havent played with it much lately to see what the possible cause is.  It doesnt indicate any spike in the wave form either.  Wierd

Open the wav in a wave editor and check whether the crackles are in the audio or not.

Try kicking up the audio interface latency one notch, maybe superior drummer is taxing your system. My previous system would crackle if certain soft sythns were playing

For my case the peaks only occur on the tracks and buses that have Superior Drummer running through it.

so turn it down. 

It's not at simple as that. The peaks I'm referring to are of 99db, its obviously a glitch somewhere.

I'll try turning down my interface latency, but its not crackling during playback like what you've mentioned. Whenever the problem occurs, my tracks will start to peak (99db) and popping and crackling sounds will occur even though its not playing back any audio at all. Then I all I can do is close the entire project and reopen it again.

Heres a pic of it:

 

my bouncebuffmsec value is 0, I haven't tried removing the plugins yet.

eliminating plugs, especially if there's the same one on those tracks, or multiple instances of one, is a good start; first delete them all... is the kick/snare tracks the only ones that don't peak? what's different about those? are they cloned tracks? good luck

Thanks for the advice, it will take me some time to eliminate the plugins then do a mixdown to determine if the problem still persists. I use several different kit setups in SD and the same problem still occurs.

I don't know if the peaks occur consistently on the same tracks, I'll find out and post some results back here.

Eliminate any 3rd party Reverbs and give that a try.  I just ran into a problem with pops and ticks on another DAW platform and it turned out to be a combination of 3rd party reverbs and a particular processor heavy delay/time adjustment plugin that is native to that product.  I could have one but not both in my Superior Drummer tracks.

Probably a bad operation in the plugin somehow. 

Hi Keith. I have a nice reproducible case attributable to Audiosnap's Groove-Clip stretching algorithm. I will file a Problem Report.
