Audio crackles

I am trying to use Skype 2.8 on a flat screen imac G4 800 with Panther. I purchased an isight camera to work with it. The troubled is, the audio is terrible. The video works fine, but the audio crackles and breaks up. Even without the video, just with the internal microphone, the audio is bad. Is the imac too old to handle skype? Can I do anything to improve it?

Thank you.
Yes, I did contact skype and went through all their troubleshooting, and nothing works. My imac meets the specifications - 800 MHZ superdrive, OSX.3.8 which is supposed to work with isight (which I had to track down on ebay). Very frustrating.
You're welcome! And thanks for the new information.
• If you have used all relevant suggestions from the external iSight testing link I offered in my initial response to verify that your used iSight's microphone records sound of quality equal to that recorded by your iMac's built-in microphone, the problem is NOT with your iSight, its cable, its connections, or the Apple software that operates your iSight.
• If you have verified that the person you connect with does not have audio problems when using Skype with anyone else, if everyone you contact using Skype gives you sound that has the same crackle, and if no app other than Skype gives the crackle sound, then the problem is either with your Skype or your internet connection.
• At least part of your problem may be that you did not review all the system requirements for Skype. Your system must meet every one of them. Check again.
For instance, "OSX.3.8" is not a valid version number of Mac OS X. The version should be a number like "10.x" or "10.x.y", where x and y are numbers.
If your correct System version number is something other than 10.3.8, use your Mac's  > About this Mac menu command to find the actual version identifier for your OS X and post it back here.
However, if your actual version number is 10.3.8, your system does NOT now meet Skype's minimum operating system requirement for Skype 2.8 for Mac OS X. Mac OS X v10.3.9 (Panther) or newer is required.
You can upgrade to 10.3.9 from any 10.3.x version using the following process:
(1) Use your Mac's Disk Utility to repair permissions (how: http://tinyurl.com/9y3ed )
(There is no need to repair Mac OS 9 permissions for this update.)
(2) Download and install the Mac OS X Combined Update 10.3.9:
http://support.apple.com/kb/DL496
(3) IMMEDIATELY following the restart that complete the update, repair permissions again.
• If your Skype problem persists even though: your system meet ALL Skype requirements, is using up-to-date software on a stable broadband internet connection, and Skype cannot help you get their software working with your Mac, you may want to try a different chat application. Some are shown here:

Audio Crackles & Pops in disk burned by iDVD

I videotape using my Sony HDV camera (1080i), and import directly into iMovie06 HD. From what I've read on these forums, that is the best way to keep the full quality HD video. I edit my movie and close iMovie. Then I open iDVD, choose a theme, and drag that movie in. I don't add any other transitions, etc. Then I choose "Best Quality," and burn the DVD. When I play it in my Panasonic Blue Ray DVD player the audio crackles and pops--it's terrible. What happened? What can I do to fix this so that the audio quality is as good as it sounds on the HD videotape or on the Mac.

Hmmm. Crashing isn't good, but no harm to try again with Pro.
iDVD's Preview isn't always accurate, but do you hear anything there?
Burning errors wouldn't typically present themselves as crackles/pops, but high quality discs are recommended (Verbatim DVD-R discs are often suggested; I like Sony as well) as well as breaking down the burning process into two steps:
1) from iDVD, create a virtual DVD by using Save As Disc Image. Test this by mounting the disc image and using Apple's normal DVD Player to play it on your Mac (try just double-clicking the image file).
2) If it plays correctly, Copy the disc image to an actual DVD using Roxio Toast or Apple's Disk Utility.
It's good to have a substantial amount of hard disc space available (10-25 gigs) and I typically quit from other applications so iDVD can have max resources available.
All the audio work in iDVD is behind the scenes and there aren't any special audio controls.

Audio Crackle

Hi folks,
I've been reading about audio crackle with Logic Pro 8 & firewire devices, but haven't seen any exact answer to my issue so here goes
The issue:
* I get an audio crackle, most often when I overdub
* the crackle can be small pops all the way to noisy crackle/static
* it's worse when I'm overdubbing on top of previous tracks, that is I lay drums (7 tracks) then overdub guitar and the guitar almost always gets behind the beat and the crackling begins
* the crackle is in the playback track
My setup:
* Mac OS 10.5.5
* per Mackie, went back to the Apple 1.2.2 firewire driver (this solved the more severe issue of intolerable stuttered playback)
* Logic Pro 8
* Mackie Onyx 1200F firewire preamp/converter
* iMac 24" Intel Core 2 Extreme (2.8 GHz); 2 GB RAM
* session runs on separate G-Audio 7200 500GB drive via firewire
What I've tried:
* turned off airport
* turned off time machine backups
* session on separate drive
* I/O buffer at 64, 128 & 1024
* put all plugins in "bypass" mode
* selected I/O Safety Buffer (then switched it off)
* Plug-in Delay Compensation - set to "all"
* 44.1 sample rate, then 48, now back to 44.1kHZ
Basically, I'm running out of ideas. It seems like I have a dedicated fast computer and the session on a separate drive. The internet and backups are turned off so as not to tax the processor. I watch the little CPU and Hardrive meters in the lower toolbar of Logic and they never seem too hot. I've played around with all the buffers (although I'm not totally sure I'm clear on the philosophy here).
So, my theories are:
1) it's the firewire driver thing -- just nothing to do about it until Apple fixes the firewire driver software in the future -- but I've heard plenty of people getting the Onyx 1200F to work with the correct 1.2.2 driver and I don't seem to be doing anything too taxing with the software and Onyx
2) buffers or plug-in delay are set incorrectly
3) maybe firewire 800 is faster and better than 400 (which I'm using) - but someone told me to use 400 over 800. Thoughts?
4) I'm making some basic error that I'm unaware of
Any ideas out there or things to try? When Logic and the Onyx 1200F work together it's a beautiful thing, but the audio crackle and latency when overdubbing makes it kind of unworkable.
Okay -- suggest away. I've searched the forums and seen suggestions that half-applied but nothing quite addressed my questions. Thanks!

A user from the Mackie forums emailed me with a solution. It's a basic workaround that is so simple it's hard to believe it works. Here goes ...
1) in Mackie's Console software > Settings > Sample Rate - change the sample rate from 44.1 or 48 (whichever you're using) to 96kHz
2) the 1200f will shutdown and restart (takes 30 seconds) - now change the sample rate back to 44.1 or 48 (whichever you're using)
3) the 1200f will shutdown and restart again
That's it. You should experience no more clicks, crackles or distortion.
Based up on my initial post (whereby I installed the older 1.2.2 firewire driver) this seems to have worked so far today. I've had no trouble doing what I describe above -- laying down a full drum kit with 7 mics, then overdubbing guitars on top of the beat. I haven't tested it extensively, but where it used to fail before today it now holds strong and works as expected.
Let me know if this works for others.

Audio crackles on export

Hello,
For a couple spots in my timeline I have to two audio tracks (of the same song/lyrics, but recorded on different nights) layered on top of eachother.
I have no issues with it in FCP7, sounds great.
On export however, the audio crackles in the spots where the audio tracks are "doubled up". I'm not sure why this is happening, because when viewed/listened to in the timeline, all sounds good.
My video is ProRes (converted from AVCHD) 1920x1080 60i. Square pixels. Sequence matches the video settings.
Audio is 16 bit stereo, @ 48.0 KHz
Anyone know what might be causing this crackle after export (same settings)?
Thanks

Check your levels when you play this part, are they in the red? If so your audio is too loud... bring down the volume.... Unfortunately (or fortunately) FCP doesn't crackle when your audio are too hot...

Windows 8.1 MSI GTX 780 Audio Crackle & Pop

Hi Guys,
Pulling my hair out with this one and I really need some help.
My HDMI Audio out to TV has worked great but more often than not I get Audio crackling and popping sounds.
Its more apparent when I launch big picture mode in steam it opens with horrid crackling sounds, if I use my USB headset its fine.
I have done the following so far;
Disabled onboard Audio in the bios - No difference
Enable XMP1 memory profile - Thought it had resolved this at first but then the issue was back within a few days
Enabled high performance in power settings - no difference
reinstalled all drivers - no difference
did a full reinstall of Windows 8.1 and removed other devices and the same issue occurred.
I would also like to add the TV is fine, speakers are ok and I have tried a new HDMI cable and other devices which don't crackle.
Scan computers have offered to RMA the card but I don't think this issue is the card the games, graphics, all function really well and I am hoping to not have to RMA the card I have come here to ask for help because I am now at my wits end trying to fix this.
My motherboard BIOS is also fully up to date
Gigabyte Z97M-DSH3 Bios F5
i5 4460
Ballistix 8GB Ram
Nothing is overclocked

Had the same problem after installing 8.1 a long time ago. Rolled back to 8 still had the same problem. Just ignored it for like a year since it only happened after my PC was on for a while and then I could just log out and back in and it would fix itself for like 8 hours. Down the road I reinstalled windows from scratch after getting a new PSU (mine was getting up there) and it was gone. I think it had something to do with some drivers or something getting messed up while moving to win 8.1. On 8.1 now and have no issues.

Hp 15-r000na audio crackling

i got my new notebook delivered yesterday, and i have noticed that the audio crackles, creating a static popping noise, whether i am streaming through spotify or listening to my own music off the hard drive. this was very intermittent at first, but i just recently attempted to watch a movie on netflix and it was even more obvious and rendered the film unwatchable, the video was stuttering with the audio too. i have uninstalled and reinstalled all the audio drivers, then i changed the quality of the audio in the setting and still it happens although it does seem to be less frequent. this still happens when i am using headphones/hdmi output. such a shame considering it would be an otherwise great laptop.

Hello, @gazmundo
Welcome to the HP Forums.
It appears that you're having issues with audio playback. I will try to assist you on this.
Start with this document:
No Sound from Speakers (Windows 8)
You can also try these steps:
Open Windows Control Panel > Sound > Under Playback tab, double click on Speakers to open Properties > Go to Advanced tab > From the dropdown, select the highest quality stereo output. By default its on the second lowest setting which is DVD quality > Apply and close.
If that doesn't help, try this:
Move from the Playback tab to the Recording tab. Double click on Stereo Mix to open the properties and repeat the steps done earlier. Go to Advanced tab, select highest quality from the drop down > Apply and close.
Please let me know how this goes.
Thank you for posting on the HP Forums.

Audio crackle/pop with new MacBook Pro under Vista

I just got a brand new MacBook Pro (multi-touch, Penryn cpu) and have used Boot Camp to install Windows Vista on it. Vista installed fine, and then I used the Restore DVDs that came with my MBP to install the drivers. The Device Manager shows that everything is installed.
All is not well, however. Whenever sound is being output, there are random crackles or pops - sometimes there will only be one every 5 minutes or so, sometimes there are 10 of them right in a row. The only clue I can find is that the Problem Reports And Solutions application in Vista says that there is a "Compatibility issue between Intel 82801GBM (ICH7-M) LPC Interface Controller - 27B9 and Windows Vista." There is no solution offered. I don't know if this problem is directly related to the audio problems, but it seems likely.
Has anyone else encountered this? Any way to fix this and stop the audio crackles?

Well after a week and a half of testing and being unsatisfied with choppy audio on my MBP I believe I may have found the answer. The cause lies in the audio API within Vista; there is a specific service (Multimedia Class Scheduler) that adjusts the priority of multimedia applications according to resources available and one of the factors that affects the prioritization is network usage.
I tried pretty much every Broadcom driver available from HP and Dell to no avail; some reduced the frequency of the pops and crackles but none of them removed it completely.
I believe the solution lies within several registry keys that control the Multimedia Class Scheduler service. Open up regedit and modify the following keys:
HKEYLOCALMACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile
Set NetworkThrottlingIndex and SystemResponsiveness to 10 each (decimal)
and
HKEYLOCALMACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile\Tasks\Audio
Set SchedulingPriority to High.
After changing these 2 keys I couldn't here any audible stutter regardless of whichever driver I used. I am currently using v1.96 for the Realtek and 4.170.77.3 for the Broadcom.

Why do my exports in FCP X have audio 'crackle' after i upgraded to Mountain Lion? (this happened on two different macs)

Upgraded both my MBP Retina 15" and iMac 27" to Mountain Lion.. and on both, my FCP X (verion .4) has crackle sounds when i export the clips and play them back..
weird.
anyone else notice this? how do i resolve this?
Thanks

Could be a few things. Let's start with the specs of the audio files.

Audio "crackles" after extended uptime

Hi all,
I've had a problem with my iMac (mid-2011 model [gestalt ID of iMac12,2]) basically ever since I got it... I suspect the problem is in software, not hardware, but I can't reproduce it on my MacBook Pro (mid-2010 model) running the same OS and same applications.
Specifically, the audio begins to "crackle" after extended uptime (typically around 20 days). This would only be mildly annoying except that after about a day or two of this, coreaudiod begins to take up 100% cpu and I get periodic mini-freezes of the entire system (mouse hang, clock hang, etc.) every time a sound tries to play. Each freeze takes maybe 2 seconds but it obviously gets really annoying, really quickly.
A reboot always fixes the problem, but it would be great to avoid having to do this. Both the iMac and the MBP are running the same OS (10.6.8, build 10K549), so the only thing I can guess is that this is related to a specific kernel extension that is active on the iMac but not on the MBP, since only the iMac has this problem.
One curiosity is that this seems to be a problem only when outputting via the internal speakers... if I connect headphones, I don't notice the problem (at least not in my limited testing). Not sure if a different kext handles output to headphones versus internal speakers, but if so, that could again be an indicator of the problem. (The Sound prefpane in System Preferences certainly knows the difference between headphones and internal speakers...)
Extensive Googling has led to zero results...
Does anyone have experience with this issue and/or know of a good solution, besides upgrading to 10.7/10.8? (For institutional reasons, I prefer not to upgrade at this time, if it can be avoided.)
Thanks in advance.

I take back the "curiosity" paragraph... today, the same stuttering/crackling is coming through the headphones, too. Looks like it's not limited to just the internal speakers.
This is quite maddening. I hope that someone might have an answer (besides just rebooting).
Thanks!

Audio crackle with Macbook pro & Panasonic HD Deck

Heres the Setup. MacBook pro, Panasonic HD 1200a, FCP 5.1.4, QT 7.2 and firewire 400 to deck.
When mastering to HD tape. There is a crackle sound in the audio. Only with MacBook, doesnt happen when mastering with SDI. I heard there is a fix with Final cut 6, Is there a patch I can get for QT?
I have 3 laptops I use this way!

I think you will find is is a problem with the deck. I had this problem a year ago never got it cracked. If you sort it please let us know. Have not tried as of yet with FCP 6

Premiere CC audio crackle and non-playback

Has anyone else seen in 7.2.1 and 7.2.0 when scrubbing or stopping and starting, the audio will either crackle or just not playback at all? It's not consistent but fairly easy for us to recreate. We're playing out of a Mac Pro (early 2012) 40Gb of Ram and AJA Kona 3 @ 10.4.8 with the Adobe package installed. Footage is Pro Res LT [email protected]
Thank you,

Sorry, I wasn't clear ... I am not using any AJA products, just Premiere on a 2014 MacBook Pro.
The only way I've found to "fix" this is to switch audio output hardware in the prefs ... I even made a shortcut for that panel.
Still a major pain.
Seems to happen also every time I duplicate a sequence which uses a MultiCam source.
Also often happens with duplicated sequences in general.

Audio crackles but is fine in FCP

I have tried exporting from FCP to QT file and using compressor (Dolby Prof 2) and the DVD crackles in parts of the DVD, this crackling does not exist in FCP. I tried making an aiff soundtrack file and I still get crackling. How can I fix this?

Soundtrack Pro, QT Pro, iTunes, Logic, Peak all have the ability to resample audio to 48khz/16bit AIFF - which is what FCP expects your audio to be before editing.

Iphone 4s usb audio crackling and popping

hi my iphone 4s crackles and pops when listening to music using usb audio playback in my car
my ipod is fine just the phone that does it
anyone know of a fix ??

The system in your car is probably not designed for use with an iPhone. The radios in the iPhone can put out quite a bit of interference. If the system is not designed for it, this can result in very poor audio quality. Try putting the phone in airplane mode and see if the problem persists. If it goes away, then it's a compatibility issue with your head unit.

PlayStation 3 (ps3) audio crackle and popping bug

I'm curious if anyone else out there has experienced this problem.
For a couple years now, I regularly render my projects to mp4 (h.264) files at 1080p for playback on my PS3. In Premiere Pro CS3, I had made a couple customized presets with all the right settings for smooth playback on the ps3, which took quite a bit of research and experimentation to get just right.
Now in Premiere Pro CS5, the few h.264 default presets I've used work really well out of the box, with one small caveat. On a particular music video I've been working on, the audio has quite a few crackles and popping sounds in it. I've researched the heck out of this, initially thinking it was a problem with my render... deleted my audio peak files over and over, changed projects to 44.1kHz and/or 48kHz, use the original WAV file, etc etc ad nauseum. What was most confusing is that I couldn't hear any of these popping sounds when I played the exact same mp4 on my computer. In fact, it sounded perfect on my computer no matter what I did. In diagnosing the problem, I connected my computer directly to my stereo (bypassing the PS3) and sure enough the audio was perfect... so...
My thinking now is it's some sort of a bug or perhaps a very nuanced incompatibility betweeen the ps3 and the mp4 file. I've re-rendered the mp4 in countless ways, tweaking nearly every encoding setting possible. So far, I've found two things that work and cause the audio to play without any clicks or pops on the PS (again, they all sound fine on the computer)-
1. Rerendered at 720p instead of 1080. Audio plays perfectly.
2. Replaced my video track with a single white color matte, rendered at my original 1080p. Audio plays perfectly.
Anyway, that's where I'm at. Given it plays so well on my computer, I'm half thinking the PS3 is on it's way out as my HTPC solution.
Curious if anyone else in the community has experienced anything like this?

Just some thoughts here. Many users have had issues (some Audio on Export) with Apple's H.264 CODEC (probably the most common one?), and have had much better luck with the H.264 from either Lead, or from MainConcept. Not sure if either have a trial, but might be worth a try.
Otherwise, I am at a loss to explain why your H.264's are producing bad Audio on the PS3 (have never used one). It is also odd that by dropping the Video resolution down, or replacing it with synthetic Video, would have the affects that you describe - odd indeed, at least to me.
Good luck,
Hunt

Windows 7 - 64bit - Audio Crackles ?

$ Hi,
I've just installed Windows 7 64 bit version and all the drivers.
The problem i have is with the latest X-Fi driver for X-Fi Elite PRO.
When i play (any type of sound) in any player i get crackles in sound even in browser (youtube etc..).
Any ideas what's wrong with the audio driver ?
I've tryed all modes, 48kHz 6bit, 48kHz 24bit, 96kHz 6bit, 96kHz 24bit.
It allways crackles.

Yes, 32bit client windows (XP, Vista, 7)?have limit of 3.5GB RAM and this is a windows limit.
However a 64bit client windows (XP x64, Vista x64, 7 x64) has no such limit.
Windows 7 x64, limits:
Home Basic : 8GB
Home Premium : 6GB
Professional: 92GB
Enterprise : 92GB
Ultimate : 92GB
I have Windows 7 Ultimate x64?so the limit is 92GB, however i am limited by my motherboard/chipset which is 8GB MAX.
If i use Windows Server 2008 R2 Datacenter?the limit is 2TB (TeraBytes) of?RAM.
Windows Server 2008 R2 (x64):
Foundation: 8 GB?
Standard: 32 GB
Datacenter: 2 TB
So the only limit to me is my motherboard and chipset support.
I have Intel 975X chipset which supports 8GB (Dual Channel) of RAM.
Info for my chipset:
975X Glenwood 82975X (MCH) RAM Support: 8 GB MAX Yes/Yes PCI-Express 6? 2 PCI-Express 8?
