The mysterious crackling noise

Yes, this is another crackling noise post. But hopefully, it will be peculiar enough to capture your curiosity long enough to provide me with an answer
Like so many others, I get crackling noises on my recordings. However, this only started occuring after upgrading to Leopard and Logic 8 Pro (which, unfortunately, happened at the same time, so I'm not quite sure which of these might be the culprit).
I mainly record to my computer using an POD X3 Live, connected through an USB interface. I haven't been able to test recording with the POD to another machine that has Logic 8 and Leopard on it, but I know that the sound output from the POD is clean of any crackling noises.
Like any good Logic user is supposed to, I started changing my buffer size and buffer range to eliminate the crackling noises, though I really didn't like doing it. I've a reasonably powerful computer, after all, and should be able to use very small buffers. I WAS using very small buffers in Logic 7 under Tiger, far smaller than I can use now.
However, switching to larger buffer sizes didn't eliminate the crackling noises, only slightly reduced the frequency at which they appear. So, I'm drawing the conclusion that this is not related to my computer power, especially since my HD and CPU meters at the bottom of the Logic 8 never go above 5-10%, at the very most.
The only thing I've been able to connect to the crackling noises is that they appear with far greater frequency when I've used the computer for other stuff before recording without restarting. So, having played a game for a while or watched a movie will almost always ensure I get crackling noises unless I restart before using Logic 8 to record.
I'm even starting to wonder if the additional GB of RAM I installed at the same time as upgrading to Leopard and Logic 8 might be the cause. But I've had none of the other common problems normally connected to a bad RAM module (random shutdowns, etc).
So, does anyone have an idea about what might cause this? The POD? The USB connection? The RAM, Leopard, Logic 8, or my removal of the curve in the new transparent dock? A particularily bad taste in movies and computer games?

@twits celso: The interface I use is the POD X3 Live. It's a guitarboard/recording interface that is connected via USB.
But many thanks for your two suggested solutions. I'll be trying them both, and post the results!
@noeqplease: The POD is very compatible with Leopard. Line6 (the makers) had the new Leopard POD drivers up on their webpage a few hours after the release of Leopard. Give me a little more credit than trying to run an USB-connected audio interface/recording device with old drivers
However, it might very well be the drivers, but no other Leopard users on the Line6 forums have reported similar problems, which leads me to believe Logic might be involved in this, somehow...

Zebra's Zebrify plug in caused random crackle noise in GB

Hi, following on from weeks of random crackle in all of my songs in GB I have found that Zebra's free plug in Zebrify is causing the random crackle noises.
I finally managed to isolate the noise to 2 tracks and when hearing the crackle I clicked on and off the Zebrify effect which dissapeared at the same time.
If anyone else suffers this I hope this helps. Equally If anyone has had probs with Zebrify in GB I would love to hear all the same.

Try "isolcpus=1" in your kernel entry.

So I have a 1.5 year old Macbook Pro (Early 2011) and since last week, it has been making a crackling noise that has escalated to a grinding noise. I went to Genius - they told me my HD was fine, but they could do nothing about the noise. I'm super upset

I have a Macbook Pro that I bought new in August of 2011. It's been wonderful up until now. Last week, I was watching a lot of Netflix for a day, but then it began making a tiny crackling noise when I started my computer. It wasn't really bothersome, but then it's escalated into a grinding noise. A loud grinding noise. I haven't been watching Netflix and barely use any of my applications. My RPMs vary when I'm idle and can go up to 5000. Sometimes, it falls to as low as 1600.
I went to the Genius Bar today and the technician did two diagnostics to test the HD and the parts as a whole. Everything was fine. I was like, ***. Anyways, I asked if there could be anything done for the fans because I was willing to pay (I'm out of warranty). But he said they couldn't DO ANYTHING. That I would have to deal with the annoying noise. I called up Apple and told them what happened and she said that there was nothing else that could be done.
I am so ****** because I did pay good money for this product and I expect to have the option to repair, ESPECIALLY since I'm willing to pay for the repair. Can anyone tell me what to do? Did anyone ever have this problem?

I would guess the fan is the cause of the noise. Suggest you take a look at it.
This site has a wealth of information about getting inside a Macbook or Macbook Pro.

Crackle noise with plug-ins at the beginning of a region

I've experienced problems with some TC plug-ins and logic. Mostly with the Brickwall Limiter and TC Helicon Voice Modeler.
When I insert one of those plug-ins in a track, the crackle noise occures when the SPL is almost before the start of the region. So, when this region starts at measure 5 I hear this crackle noise somewhere in measure 4 (also in the bounce). And here is the most stupid workaround!! I have to place a dummy region before measure one of the song. Now, I can bounce the song (from measure -1). I still have this crackle at the beginning of my bounce (before the music starts) but now I can cut it because its at the beginning of the song. The crackle doesn't occure a second time, only when the first region on this track is passed.
I had some consultation with TC and they asked me to send them a file although they didn't know about this phenomenon.
They also recommended to experiment with "automatic delay compensation" and buffer size but it didn't help. Any ideas??

Logic's process buffer and/or disk buffer size.

I have installed the new OS X Yosemite and now my FaceTime is causing problems. I can make and receive calls, the recipient can hear me, but I can't hear them. All I can hear is a crackling noise. The speakers work fine for everything else.

Got the same problem – even after the upgrade to OSX 10.10.1. A restart usally helps. Even though the calls sometimes drop I got no crackling noise problem on iOS, though.

Crackling noise when rotating the headphone in the jack?

Is this normal? With the headphones that come with the iPod, I don't get this.. but I bought a different pair.. and they make a crackling noise when i rotate the connector in the headphone jack. Is this normal? Would I experience this if I upgraded to another headphone? Would it be different with the iPod in-ear headphones?

The crackling noise should never happen. The headphones must be defective. Return them to the store, buy another pair, and try them at the store before purchasing.

Crackling noise while viewing Sky TV in bedroom using RF cable

Hi, We currently have a sky box in the livingroom. As we seem to have a really bad signal in our bedroom we cannot use freeview in there. We also cannot get Sky multiroom as we live in a flat. We now stream Sky from the livingroom to the bedroom TV using a RF cable from Sky box to output in livingroom and RF cable from output in bedroom into that TV. This generally works well and the picture is ok however we get a loud crackling noise every so often that we cant seem to stop, lately this noise has gotten more frequent and louder. Can anyone advise why this is happening and how to fix it? Thanks.

Hopefully that will make it easier to fix!
Try changing the RF Output Channel your Sky box is using. By default it's set to channel 68. Try a channel at the other end of the range - say 25.
To do this. key Services,0,0,1,Select on your remote to get to the Installer Menu. Don't pause between key presses, don't wait for the screen to change and don't forget the Select at the end! At the Installer Menu, you'll see the RF Output tab where you'll find the Output Channel setting. Change to 25 and press Green to save the change.
Onceyou've done this, you'll need to re-scan for channels on your bedroom tv, using its setup menu.
You may need to try several RF Output Channels before you find one that works reliably.

MacBook Pro 13" makes crackling noise

My MB Pro that I got this year just began making a crackling noise last night when I touch the plastic port on the hinges and when I adjust the screen back and forth it makes that noise aswell. I just wanted to know do I need to be worried that it's a major problem or can I look past it? Any damage on my MB Pro in the long run due to the plastic part of the hinge?
Thank you.

Take advantage of your warranty and have Apple check it.
Ciao.

Samsung TV-HDMI Cable Crackling noise during video play

I have a Samsung Plasma 50inch. Just connected the HDMI cable and audio/video works great except when they're working at the same time. If I watch any movies/videos, there is a crackling noise coming from the speakers. (If I mute the TV, the crackling noise disappears.) Any suggestions on what I should do? New cable? TV issue? I'm currently using a Belkin HDMI cable.
Thanks!

It could be a problem with the cable box. Connect your cable directly to the TV and see if you still have this problem, if you do call Samsung, if it goes away call your cable company.

Static crackling noise, Right speaker when audio is being played

I recently purchased this Satellite C50D-A Windows 8 Laptop. I have had it for less than 3 months. Recently the right speaker has started acting up with some sort of high pitched static crackling noise whenever audio is played regardless of it being in a web browser or any other media. Even computer sounds are distorted from this. I typically use this computer for school and play music to study. How the hell can I fix this so I can actually listen to audio without this rather irritating issue?

I tried that and it didnt seem to do much of anything.
I played part of a song on spotify and recorded it to perhaps give you an example of what it sounds like?
I covered the left speaker so most of what you hear is the right speaker alone. The distortion is pretty clear when audio comes out of that speaker.

Nokia 5610 with crackle noise when use headphone

hi everybody !!!
i am using nokia 5610 XM,it's realy great music phone but when i listening music with headphone sopmetimes i can hear the crackle noise
but when i play the same song by mp3player with the same headphone i can find the crackle sound
What happend with my phone, may be the sound chip has problem ???
Solved!
Go to Solution.

ders a few reasons y that may occur, there could be something wrong with the 3.5mm av in port, it could be dirty or damaged, or it could be a software thing where the music isn't being sent through as complete data through the connection. der r other reasons, either way, i would advise you to see a nokia care centre, especially if your warranty hasn't yet reached its void.

Crackling noise on my mbp

Hi there,
I bought my macbook around December-ish and now for the past few days I have been noticing random "crackling" noises. They are soft but getting louder, or maybe I think that because I am watching for them. Before they used to just come from either the right or left end of my mbp, but now I can hear it in my headphones too when I have them plugged in. I tried Antipop without help and have searched various threads on here without finding a solution for my problem. I was wondering if anybody can tell me the reason and how to resolve it.

Hi patel822,
I'm sorry to hear you are having issues with random noises on your Macbook Pro.
The article below is a general troubleshooting guide for sound issues.
If the issue persists, there are addtional support options in the article.

I hope this information helps ....
Have a great day!

AUPitch results in crackle noise

Hello! I'm having an issue with the AUPitch filter when applied to perfectly fine audio. The audio is sped up (anywhere between 110% to 130%) and then I apply the AUPitch to correct the pitch change. This results (intermittently) in a crackling noise being introduced into my audio.
Any solutions? Are there any third party audio filters for FCP? Should I just send the problem clips to to Soundtrack Pro?
Thanks!

if the built in pitch shift plug is not working for you then you can always pursue alternative options ... how hard do you want to make it?
you can bounce the clip out to SoundTrack Pro and do some pitch shifting there
or try an alternative (and free) AU pitch shift plug in such as Octave Shifter from Audiowish
