Pop Crackle Sound at Each Audio Edit Point

Hello!
For the life of me I can't figure this one out.
I am working on a video using Final Cut 4.5. I am using audio that I have separated from the video image. At every AUDIO edit point (beginning or ending) I get a pop or crackle sound.
I have tried cutting out the ends of each segment but that does not help. The popping sound always occurs at the ends of each segment no matter how long or short they are. The audio was captured at 48khz, 16bit and was originally married to the video.
Any ideas?
Thank you!
Ann

This happens everyonce in a while with me. At those points I'll add a 5 or 6 frame audio +3db dissolve. It should clean it right up.

Getting crackling sound on any audio on X305-Q701

Any audio that is playing (internet, itunes, rhapsody, video games, etc.) is getting a crackling sound. Anyone else getting this? or have a fix
Solved!
Go to Solution.

Try to update the audio driver of the computer.

Just open that link and download the Realtek Audio Driver for Windows Vista and install it on your computer. Restart the computer after that. Hope this one works. Just tell me if its not so i can give you some other steps.
Thank You.

Exs24 crackling sound at the start of each sample

Hi
I just installed project sams true strike 1 and 2 on the exs 24 sampler on Logic Pro 8.0.2.
My problem is that every time i play a note on the keyboard there is always a popping/crackling sound at the start (attack) of the note. When i go and listen to the sample in the sample editor there is no such pop/click sound.
Is there a way to solve this problem?
I would be thankful for any advice or assumptions!

Hi Jupiter,
unfortunately we saw this message only today.
The crackles you are getting happen because the original library was developed by Project SAM using a set of samples, and then at the last minute they swapped the sample files with a different set of files without updating the instruments for the changed files.
There are several commercial libraries that unfortunately have this problem, and Project SAM is a known one.
Normally you do not see this problem in Logic, as Logic can see and fix the problem itself silently without teling you anything. When you relink your library with ExsManager, however, Logic thinks the instrument is already ok and will not fix the problem itself.
ExsManager by default will not fix this problem either, because we want the user to be in charge of what is done to his library (i.e. we do not want "magic" to be performed).
It's not a big problem anyway, and you can use ExsManager to fix this:
-start ExsManager
-switch to the advanced mode
-click the "Reset settings" button to start from safe settings
-set SampleDir and InstDir as you you need for your library (should already be set as last time you used it)
-switch to the "Options>References page and enable the "Check and fix sample format inconsistencies in instruments" and "Force refresh for all references"
-click "Analyze"
-click "Process"
... and that's it.
You do not have to do this every time: once the instruments are fixed you can relink as usual.

How to fix streaming audio pops/crackles and then stops all sound

I am a google Chrome user. I am unsure if this problem is related to Chrome or to Flash by I suspect there is a problem with both. I previously had this problem where when you start a youtube video for example the audio would pop/crack and then the audio would go dead. If you were able to put the video on full screen before this happened it would work fine. This really only happens with windowed (non-fullscreen videos). Previously I went in to my chrome plugins and disabled chrome's native flash and that fixed the issue. With the most recent update to Chrome this has happened again. This time disabling chrome's flash does not work. On the adobe version site it says that for chrome the version should be 11.5.31.137 but it shows me as using 11.5.502.146. The latter would be the version for firefox. I do not use firefox. Could this be causing my trouble? I have used the official flash uninstaller and restarted my computer and reinstalled but the same thing happened. Thanks.

Thanks for the link. I have tried what they recommend. I currently have two flash files. I have disabled the chrome one and the one that is enabled is C:\Windows\system32\Macromed\Flash\NPSWF32_11_5_502_146.dll
However, I ran the chrome://flash and this is what I got:
Flash plugin
11,5,502,146 C:\Windows\system32\Macromed\Flash\NPSWF32_11_5_502_146.dll (not used)

I've never looked at this before but it is weird that it is saying that that flash is not used.
Anyone know about the firefox version of flash installing for Chrome because as I described above that doesn't seem right.

Time-remapping audio artifacts - pops/crackling/static

I'm still not entirely sure why it happens but when I slow footage down with time-remapping in AE CS5-6 I can most of the time get these 2-3 frame audio popping sounds ( best way I can describe it, you could also describe it as a static spike or crackling sound, something that is noticeable different from the slowed down audio ). However I don't get it at anytime during ram previews, I'm only hearing them with rendered footage. Normally I'd just take those rendered clips and reduce the audio levels for those 2-3 frames but I'd like to see if there is a way to avoid it entirely.
I've tried rendering in various codecs and matching the source footage settings exactly but haven't had any success in that direction. Again it's not in the source and it doesn't show up in ram preview, only after it's been rendered do you hear any of it. Any input and possible alternative approaches to solving this issue would be great I've run out of stuff to try.

I don't believe the source is using MP3 or AC3 for the audio but I do believe it has some slight compression. It's nearly lossless so I don't understand why rending something with heavy time-remapping using something like Lagarith would cause these types of artifacts.

Crackling/popping/garbled when using USB audio iPod iOS 6.16

I know several people are having this issue. iPod touch with iOS 6.16, when using the USB cable plugged in to Ford Sync or other stereo head units with USB connectivity, I hear a random popping/crackling/garbled sound. The iPod does this on 2 different vehicles so I know it is not the stereo it self. I have a 2005 Chevy Silverado that I added the IS-GM655 adapter to install a USB and AUX port. Also I have a Ford Van that has the SYNC system in it.
When the iPod is plugged in to the stereo via the USB port, I get random popping or crackling like a CD skipping from the audio. When the iPod is connected via the AUX headphone jack, I don't seem to hear any popping or crackling. I have tried cleaning the port on the bottom of the iPod with rubbing alcohol and it seemed to help a little, but I still noticed the popping/crackling/garbled sound coming from the USB connectivity. Also, Bluetooth and WI-FI are off, I even tried airplane mode and different USB cables, still get same symptoms.
Any fixes for this yet, it appears from all of the other threads I have read and googled, there are SEVERAL other people experiencing this issue and nothing has fixed it??
The only thing I use the iPod for is music, there are no other apps installed on it currently.

Hey Relentless85, Have you tried a "Cline Free" dryer sheet? ! OK, done messing around. It's static electricity, why I have no idea. In my Toyota, I have this issue, The other half's Toyota-- no issue! (go figure) It's always worse in the winter, and only with one adapter. As long as you don't touch the iPod, move it or look at it for to long, your OK. But do any one of the listed activities, you know use the iPod-- it clicks and pops likes a bowl of Rice Crispy's. This helped me, it's going to sound stupid and shouldn't work but it does help. Get yourself a grounding tether, the wrist strap with the wire, the thing you wear when working on computer's, anyway place the strap on your iPod, so it touches the metal back, and the other end attach to some part of your vehicles frame, not to any of the wiring! It shouldn't work but it does for me. The garbled sound, does it it sound like the feedback noise from cassette tapes? (Maybe your not old enough for that...) or over metered sound? A distortion or rumble? Try turning off the EQ feature on your iPod or put it on FLAT, or reduce the volume output level from your iPod to about 80% - 85%. It could be the iPod is sending a frequency that exceeds your car stereo's range, (over metering. On analog tape you did this to boast the bass, but the same practice in digital format causes distortions). About the only other thing to try is Resetting or Restoring, but I don't think it will help in this case. If the tether ground helps, it static, if not-- then you cleared out one thing to check. Hope this helps, Good luck. Cheers.

Nvidia MCP51 - ALC883 Audio chip: crackling sound

I got this problem for some time, i hear loud crackling sounds over the sound output when i play mp3s or movies, or any other media file, but i hear without problems the pcspeaker and the microphone works perfecrly, i can clearly hear my voice. This happens also with 1.0.15 (at least on Gentoo) driver but now i'm using 1.0.14 on this new installation of arch (i'm an arch newbie that changed from gentoo), my mainboard is an ASUS P5N-E-SLI with an integrated Realtek ALC883 soundchip, the module that alsa is using is snd-hda-intel, I don't know what autoprobing is doing, but i've tried model=3stack-6ch-dig with the same results.
Also the mixer behaves in a strange way, with no master and a headphone control with no bar but with only the unmute/mute buttons.
I think that archlinux is very good, and i'm trying it because is always at the bleeding edge of updates.
Hope i can finally fix this problem, now i'll try to recompile the kernel and install the latest alsa driver 1.0.15 from source.
Meanwhile if anyone has suggestions is very welcome!

Well i wish you luck pal, maybe it's my configuration problem, i've also thought at an irq conflict... at least you can be a tester

Any help?
I've read a lot this topic, the problem is fixed for the chip on acer notebooks, the model used is model=acer, in the 1.0.15 version the best model for the ALC883 of the ASUS-P5N-E is model=3stack-6ch-dig because is a 3 jack, 6 channel with s/pidf, but for me the problem remains, whit model=acer i totally don't have sound.
It's difficult to say that ALC832/3/8 are supported there are a lot of configurations that may cause problems for now, probably in the next alsa release theese problem will be solved.

Audio extracted and deleted but short noise remains randomly at edit point

the more I paste over at playhead and extract audio the audio bug occurs at edit point which then cant be deleted (titles or transitions not used)
Can anyone suggest how ot fix this
Cheers
Mike

Hi Sue,
Thanks for your reply.
I have zoomed in on the timeline and the audio files are always completely deleted.
I extract audio a lot when making a programme as I feature interviews with inserts pasted over at playhead. It seems the more I do this the more likleyhood of this audio bug occuring randomly. If you had any workaround ideas they would be much appreciated.
I dont use transitions or titles when this fault occurs
Regards,
Mike

Crackling sound, Electrocuted? Popping, and low frame rates.

First, I hear a crackling sound in my headphones, and you may think I am crazy, but I get nauseas and feel a slight tingle, as though I am getting shocked.
The fram rates drop to about 7fps while I am playing games, and I hear the noise and feel this. I first noticed this when playing World of Warcraft, then, after shutting the game, I noticed it continued while I was using Ventrilo, and then even after it continued.
It seems to stop after 20 seconds soemtimes, and other times can last for several minutes. I have taken my headphones off and even unplugged them, but notice the popping continues in the internal speakers.
I do not think it is the game, as it happens outside the game, and even outside ventrilo. I am not sure why my headphones would / could shock me, but I swear that is what I am feeling. I tried making sure I was plugged into a surge protector, and have tried other plugs with it happening the same.
It does not always happen. Some nights it will not happen at all, and others, it seems to happen every 30 minutes or so.
I am using a MacBook Pro 17" non glossy. 2.16 Core Duo. I have 2Gigs of Ram, and other than this, the computer works great.
PLEASE, if anyone else has had this problem, let me know. My FPS in game go from 50, down to 8fps, and in general the entire computer comes to a crawl.
Thank you,
Nicholas

Hi there,
I am not at all an expert on gaming and dont have any on my MBP, however what i can recommend you is the usual maintenance motions you can follow.
1- reset the power management
Disconnect the AC Adapter and remove the computer's battery.
Press and hold down the power button for 5 seconds and then release the button.
Reconnect the battery and AC Adapter.
Press the Power button to restart the computer.
http://docs.info.apple.com/article.html?artnum=303319
2- do the hardware diagnostics
Boot from the installation DVD that came with your computer while holding down the D on the notebook's keyboard. Choose extended diagnostics for more comprehensive tests.
Report back please

K7T Turbo R Limited Edition and crackleing sound

I started getting a crackling sound recently. I never had that problem before. The only thing I can think of that I have done that may have started it was to update the bios and the via chipset drivers. I tried to reinstall the 442 drivers (only the pci part) but no change. I reinstalled the 443.
I read in other threads that it could be either a latency problem. Also moving the sblive sound card could do fix the sound. I don’t seem to have any latency timing adjustments in the bios and I tried moving the sound card to number 3 and the number 6 slot with no luck. I have tried a couple of 686 bug fixes and they didn’t work. But I have also read where that wouldn’t work so I removed them.
Is there anything that might work?

Crackling Sound with Itunes

After giving up with pci-e extreme audio because of latency issues, I bought the pci-e fatalty pro pci-e. One of the problem is, there is a crackling issue when i stop and play another playlist in Itunes. You can fix it by changing modes.(i.e from entertainment mode to audio creation mode) but then again after you change playlists, it does it again.

I am unsure if this will help you or not. Itunes has an add-in setting which in my opinion only, may be similar to our using CMSS3d with our cards, etc.
Disable the Sound Enhancer feature in iTunes:
1. Open iTunes.
2. One the Edit menu, click Preferences.
3. Click the Playback tab.
4. Deselect Sound Enhancer.
and now see if you get the same crackles pops or sound playback problems. I disabled that setting on mine from the beginning, but hopefully you can toggle that setting and see if that helps you.

Edit point glitch in Preview

Hi All,
In a simple title sequence, I cut from a title frame with white letters on black to the same type of frame with a line added. What you see is a main title and then a subtitle pops on under the main title.
This looks perfectly smooth in FCP and the Quicktime conversion. But when I play it in DVD preview there's a jump or glitch at the edit point. Not a smooth pop-up.
I wonder how to fix this. I don't want a "mistake" in the DVD file that's created for burning.
Thanks,
Robert

If you stay within FCS2 / apple's pro apps exclusively (meaning FCP => DVDSP) then yes you can address this issue with many more tools at your disposal and with far better results (especially for audio, titles, and extreme fine tuning).
However this is not the case with apple's i-apps. High Precision modifications become more cumbersome within apple's i-apps because the supplied tools have more limitation and are IMO overly standardized in an attempt to make them more user friendly.

PE-10 Cannot hear sound files in preview, editing, or final movie. Works fine outside PE-10.

While editing a movie, the sound attached to video files plays fine. When I import other sound files (such as wav files), they will not play in the preview, editing, or final movie. I've tested the files to make sure they are fine (yes).
I've tried them in each audio/sound section and they won't play anywhere. I've checked setting to make sure audio is enabled.
Please help. I assume something is not set correctly.

Well, if you've got Audacity, you can make them good!
Just Export your file as a new WAV file. Audacity will output the new file with specs that Premiere Elements can work with!

Help with Audigy 2 Zs and crackling sound ..

For the past 5 months or so ( not long after I got the product ) I have been getting this periodic issue with the sound ...
I'll start to notice a popping and crackling sound coming from the left channel when loud sounds issue from the game ( multiple games ). After a while I figured ou ttha tI could :
a: Reset all my settings to Default , Then reconfigure my surround
or
b: Reinstall and/or patchthe current driver set ...
Both seem to fix the issue for some time then it all returns within a month or so .... It's a rela pain to have to keep configuring my Audio settings every month.
My system specs are
Asus A7N8X DLX Rev. 02
AMD 3000+
Gig Corsair XMS
BFG 6800GT 256
Audigy 2 ZS
Raptor 74 Gig
and some Altec Landsing Speakers ( I forgot the model number )
Any idea what could be causing this ?
Thanks in advance.

I got the fix for you twellons. Just go in the audio control panel and mute the midi/synth in the panel and you will have the fix. My system specs are close toy yours amd 2800xp, nforce 2 a7n8x dlx ver .04 and a original audigy card. Now creative has to address this issue in new drivers. Also download the demo of contract jack and when you load the game and the game menus comes up, scroll through the options in that menu like new game, load game quickly and you will here that popping noise in only the left speaker. and when you do that fix that i mentioned above, no more popping . So try that out and please get back to me and tell me if it worked or not. That issue was tough to figure out.
P.S. You owe me

Captivate 4 - audio editing issue (distortion heard once published)

Hi -- I am working on a 17 minute movie with audio on each page (total project size about 60mb). I recorded the audio outside of Captivate and imported the .wav files (for some reason the .mp3s sounded too tinny). When I started the project in November I had no problem editing the files (removing sighs/pauses, inserting silences) and adding to the slides.
For some reason in December I started running into issues. I would go to edit a sound file on a slide, it sounded good when played back, but when I previewed or published the sound file I just edited it would have a layer of sound on top of it making it distorted. Also, I no longer have the ability to add silence at the beginning and end of the audio file (which I was able to do in November). I add it in edit mode, can see/hear the pause but when I save and close out those beginning and end silences disappear.
I just got final feedback and was making adjustments on two slides but the same thing happened. The audio files I edited would sound distorted when played back in swf form. The only way to save the project was for me to open an old archived version, export that audio, re-import to my production project and it worked fine. But I cannot edit it in Captivate. If I do, the distortion gets added.
I am publishing as audio quality: MP3, 96kpbs, 44.10 KHz.
Any thoughts? I like to edit directly in Captivate and don't want to have to do the extra step of editing the audio in another application.
Thanks!

Hi there
If you want to add silence at either end, your first step will need to be to position the playhead ever so slightly away from the true end or beginning. Otherwise, Captivate ever so helpfully discards the silence. So the silence needs to be inserted between the ambient noise.
Actually, this is a nice segue into a technique you may wish to use. Select a section of the ambient noise and paste it repeatedly. This will eliminate the "dead air" you hear with total silence. Sometimes inserting silence is one of those - "the cure is worse than the disease" sort of things.
Cheers... Rick
