Im not a pro by any means... I guess I should tell you my setup first.
Sonar 3 Producer Edition, PreSonus Firepod, Behringer Composer Pro-XL, Aphex 204, many plugins.
I had a problem with this crackling noise and i narrowed it down to the guitar tracks. It seemed to be a problem with having too many guitar tracks at once. I had 8 tracks (4 seperate parts, each part with 2 mics on a cab.), the volume was not loud enough to clip and even if I turned the volume WAY down on the tracks, it still crackled. I asked a guy i know about it and he said I needed to pan the tracks out of the way of each other. That seemed to work, but I would like to know what this is called and learn a little more about it. If its too complicated to go into here, I would be grateful if someone could post a link to a helpful site. thanks a lot!
PS: Ive noticed this problem in some professional recordings too, but mainly with the toms. IE:Simple Plan, The Ataris... big name stuff.

Oh and another thing... I got in the habit of using 96k sampling
Oh and another thing... I got in the habit of using 96k sampling rate back when I had a MAudio Delta series card. Using the higher rate with Sonar 3 produced a lower latency for some reason or another. I currently use a PreSonus Firepod which uses ASIO drivers... will lowering the sampling rate hurt the latency at all? I dont even know why raising it helped the latency in the first place but it did. Cut it in half unless my memory is failing me.
i have no idea as to why an increased sample rate would reduce c
i have no idea as to why an increased sample rate would reduce clicking. the bit-rate increase, although taxing the system harder, helps because it puts the errors down in the lower volume registers. at least that's my theory on why it works.
but increased sample rate? no idea why that works.
since you said that the latency was halved, i guess when you increase the sampling rate every component of the system increases in speed by the same amount, thereby halving your latency when the sampling rate is doubled.
but it's a huge waste of disc space. I would stick to 44.1kHz/24 bit.
Because generally speaking, most music these days will end up on CD which is 44.1/16. The reason you record at 24 and not 16 is that processing and effects cause some loss in the signal (inherent in the nature of the effect) even on a computer... it's better to be starting at 24 and working your way down in quality because you'll still probably have more than 16 bits of error free audio. Only the quietest of quiet parts will have errors. (errors are pops and clicks)
when you are mixing down make sure you use a dither plug to go from 24-bit to 16-bit. It helps alot, especially in lower volume areas where errors are more noticeable.
I use monitors. The problem seems to be noticeable at all volume
I use monitors. The problem seems to be noticeable at all volumes... have you guys ever heard it on a pro cd? I can hear it when the drummer does a roll from snare to toms high to low. Of course it pans right to left, but on The Ataris cd So Long Astoria, its plain as day on the 14th track. Every tom hit has crackling accompanying it. I dont know, maybe thats just them mixing loud for pop stations...

sndo wrote: definitely lower the sampling rate. going that high is completely unnecessary, unless you're of the school of belief that humans actually DO perceive sound above 20 kHz on some kind of subconscious level. 44.1/24bit is fine.
IF you have speakers that will respond over 20k and a tone generator that will generate a sine wave over 20k, just try running a 20k+ sine wave loudly through your speakers and then tell me you don't at least feel it as pressure. Be careful not to fry your tweeters btw...
In the early 90's, engineers at JVC ran double blind tests with subjects listening to audio both in analog and digital formats and their obsevations showed that these subjects had much more brain activity with content over 20k.
Most women can hear well over 20k .... my wife ears are good out to 24k (confirmed by an audiologist).
As for the crackeling, I have heard this too and the way I solved the problem was to back the mic off the amp a few inches ... this may be the problem.
If you have all the guitar parts panned center and then solo any
If you have all the guitar parts panned center and then solo any one of them are the bad sounds evident in any one of the tracks?
I use sonar 4 and sometimes here cracks and pops that never show up when I export or mix down to a final. I think sometimes it is actually my video card or RF problems from the monitor cable. As long as they don't end up in my mixes I don't worry too much about it.
