Trying to get rid of pops

Ok, so this post definitely belongs in this section of the forum. I've just gone back to an old rig I havent used in a while, and I'm getting those damn "pops" in my music. Here's what I'm using

Shure KSM127, into a presonus firebox, into Cubase via firewire, on a pc (acer).

I found today while I was recording acoustic guitar, I was getting these sort of "pops" in the recordings. It didnt sound exactly like a pop you get when wind hits the mic, its somehow more crackly. When I played through the mic just on monitor, there was nothing, but after I hit record they would come in randomly. I then tried to use a pop filter, turn down the mic level, use a pad, and even changed the bass rolloff, and nothing worked. I went to change my buffer size, but saw it was already maxed out. Whats more, when I recorded voice, I didnt hear any pops.

What the hell is going on? Am I crazy? Someone please help.
 
sounds like a problem with the interface. pops like that can happen when there's issues with the signal communication. try increasing the buffer size.
 
Yeah, I had a firepod that started doing that. I changed buffers forever and then just ditched the unit altogether. I really do think that in my case, it was a hardware issue.

The USB stuff seems a lot more reliable these days.

But hopefully you can fix yours with buffer settings.
 
My buffer size is already maxed out, will making it smaller help? And I know this setup can work right, it did a couple years ago when i used it primarily for recording
 
Put him in the car, drive him several suburbs away, open the door and shove him out. He'll never find his way home...
 
That helps alot guys. Thanks for being dicks, I'll remember it

Someone needs to lighten up - no wonder you and your pops don't get along.




if you post a mp3 of the problem might help you get an answer.

Limetree... take a joke for goodness sake. You've been here three minutes and you're telling people off?

There's lots of helpful people here, indeed, I'm one of them, except not in your particular case as I don't use interfaces and so can't really help you... so if I poke some harmless fun at your thread title, don't take it personally...

I remember too.... I'll remember you the next time you want some help and I know the exact answer...

Bit of patience and tolerance and you might get your answer...
 
Try looking at the CPU Usage meter, see if its clipping whenever you hear a pop, if it do, then you need to increase you buffer, if its maxed out and still poping, maybe you need to upgrade your RAM
 
Whoa. Just got the joke. As for the long reprimand for my lack of humor, cool story bro.

Is it possible that the pops and such are related to the amount of space on my harddrive? Because after I deleted alot of programs and defragged the disk, I noticed the pops were less.
 
tell us about your computer a little bit: processor speed, how much ram, how much free space on hard drive...
..or maybe you have just too many processes going on at once - quit all programs except cubase, turn off wireless.
 
I usually get pops on my recordings when the cpu is under load or if large apps or soundcard is battling for cpu resources.
Id check task manager to see what the resource usage is when running Cubase and shut down any unecessary apps etc.

Takes one to know one ~ na - na - na - na - na - na - na - na - na - na - na. :p


Your problem may be the microphone it's self!

I've had two microphones in the KSM series that had grounding issues.
One I fixed by tightening the screw of the body of the mic, the other had to go back to Shure to be fixed ... free of charge.
 
Pops from the interface is normally a resource issue. I/O bottleneck, or CPU over taxed, and other computer version of excuse me while I clear my throat. (or failing hardware)

It could also be mechanical noise. Unawareness of smacking the instrument while playing, or tapping the foot on the leg of the mic stand. Is the mic in a shock mount? And the cable kept fairly slack in proximity of the shock mount?

A sample would help ID it better. Is the frequency consistent? (mechanical) Is it random with inconsistent peaks? (resources) Is it 5x's louder than any actual sound should be at those levels? And other identifiers.
 
Hey guys, turns out its definitely cpu load. Thanks for the opinions.
