Strange "Audio Stutters" in All Exports

Hello,
What I can only describe as "audio stutters" occur at seemingly random times in my Premiere Pro exports created with Media Encoder. They are very brief but noticeable intrusions that sound like glitches.
All audio sounds perfectly normal in Premiere; there are no problems on the timeline. I have tried the following troubleshooting steps:
Restarting the computer
Restarting the software
Cleaning Premiere's cache through the preferences panel
Changing the Renderer to "Mercury Playback Engine Software Only" in Media Encoder
Unchecking "Enable Parallel Encoding" in Media Encoder
These "stutters" occur in all exports; I have experimented with different projects stored on different drives, as well as with different formats (ie., H264 and Quicktime) and audio codecs (ie., AAC and MPEG).
The only way I have found to create an export WITHOUT "stutters" is by sending a sequence to Audition, creating a mixdown file, importing this file into Premiere, using it to replace the original audio, and then sending this single-audio-track sequence to Media Encoder.
I would love to be able to export from Premiere without having to run my audio through Audition. Any and all leads are welcome!
For your reference, I am running Premiere Pro CC on Windows 8.1, with a 3.60 GHz processor and 16 GB of RAM. I have 11 GB available for Adobe products. For what it's worth, I know for certain that I did not experience this problem prior to the 7.2 updates.
Thanks in advance!

Clearing the Cache is best done outside of PP using Windows Explorer. You can get the location of those files under Edit>Preferences>Media...
(On a side note, this Cache cleaning could use some improvement. Please add your vote. http://forums.adobe.com/thread/1369263?tstart=60)
If that changes nothing, it would be helpful if you could upload a file somewhere for us to hear the issue.

Audio stuttering in all browsers

I am having a constant issue with audio stuttering when playing videos, which has persisted for a couple of weeks now. This occurs in Firefox, Chrome and Internet Explorer.
I have tried downgrading to previous versions of Flash (including both 10.3 and a previous 11.X version), and (unless I am not doing this correctly) this has not fixed the issue.
I have even attempted to solve the problem by resetting Firefox, and then upgrading to the latest 15.0 beta, but this did not work as well.
Is there anything else I can do to resolve this issue, or is there something more fundamental broken with my machine? (I ask this as I have had problems with both Windows Update and a virus recently, and before these issues I did not have any problems with Flash playback.)
I am running Windows 7 on a Lenevo G570 laptop. I am currently using the latest version of Flash (11.3.300.268), and before I upgraded to the Firefox 15.0 beta I was using Firefox 14.1. (I believe that both Chrome and Internet Explorer are up to date, but I predominantly don't use these browsers.)

Audio stuttering problems with certain exported MP4 files

I'm currently running Captivate 6.1.0.319 on my old and decrepit Pentium 4 machine that has 4GB of RAM and is running Windows 7 SP1. I'm developing an online training course on RoboHelp 10 for Udemy, and they require all lecture files to be in MP4 format. Unfortunately, some of the MP4 files I generate from Captivate have audio stuttering starting a few seconds into the generated video and nothing I try fixes the problem.
All the videos are being recorded with video dimensions of 1360 x 978 pixels. I import the .cptc file I recorded into the .cptx file, and then I import an MP4 audio file into the .cptx file. When I finish editing the .cptx file, I publish it to an MP4 file using the highest video settings and the highest variable bitrate audio settings.
I have tried the following to try to fix the problem:
Turned off SWF compression.
Created a new .cptx file and copied the slide from the problem .cptx file into the new one, and published that new .cptx file.
Disabled all software operating in the foreground and the background.
Tried generating the MP4 file on my laptop; the laptop runs the same version of Captivate on Windows 8.
As I said, Captivate generates some MP4 files perfectly without any stuttering, and others have the stuttering problem. If this problem sounds familiar, it's because I wrote a couple of messages about this a few months ago and despite some good suggestions, I wasn't able to solve the problem. I've spent my time during the past few months trying to find another program that will convert SWF files to one of the formats Udemy supports -- MP4, MOV, or FLV -- without success. Captivate exports to SWF and HTML5 format files without any trouble at all. But MP4 generation is spotty and I need to get this resolved so I can get this project off my plate and start making money off it.
If you have any further questions, please let me know. I look forward to hearing your suggestions.
Thanks,

Hi,
I am having the same issue and cannot figure out what is causing it, as it occurs randomly - but fairly frequently - when I publish to mp4. And it is not tied to the project - seems to be something happening during the publishing. The issue might occur one time when pubishing a project and if republished again it may or may not occur again. I would be very interested in finding exactly what is causing this and any step that are tested and proven for getting away from the problem.

ALL Flash Audio Stuttering: YouTube, Pandora, etc

Within the last few days, something must have updated that is causing ALL my Flash Player streams to stutter miserably while playing in either Chrome or Safari. This inludes sites like YouTube, Pandora, Grooveshark, Spotify, etc.
I'm running Mac OS X Version 10.8.5 on a MacBook Air 1.3Ghz Intel Core i5, 8GB 1600 MHz DDR3.
Adobe Flash version is the latest version.
The stutter is an infrequent clicking that sounds like my speakers are being destroyed. Strictly a Flash problem because all local music and non-flash players play audio perfectly.
Please help or participate if you're having a similiar problem.
Best,
MM

Hello,
I use:
- a MacBook medio 2009
- OSX Mavericks (10.9.1)
- Latest Google Chrome version 33.0.1750.117
- Latest version of Flash Player at the moment (12.0.0.70)
I did the following in Chrome to get around the problem (in chrome://plugins/):
If I remember good, I've had the audio stuttering problem about half a year, a year, something like that. I'm not using my MacBook daily but when I played some music for example with YouTube , It annoyed me a lot that the music stuttered when I opened a new tab in Chrome or when I was typing when I Googled something. Also when loading a page or clicking a link the stuttering occured.
I tested If the problem occured when my laptop was plugged or unplugged but that didn't alter the behaviour.
I guess the problem just occures when there are two or more flash-plugin entries in the Chrome plug-in tab enabled. Why would you need two Flash Players to play a video or audio etc. anyway? I guess it's just some conflict between the two plug-ins but I'm just a simple guy that does a wild guess.
I hope you can do something with this info
cheers

Major "BUG" in Imovie 9 - Audio Sync Problem on Export !

Well I'm a hard-core Apple user from day one, but unfortunately today I'm not to proud about the latest version of Imovie 9.
It seems there has been a "MAJOR audio sync problem on export" in Imovie 9, since July 2009. Apple knows about this bug for a long time now, but didn't release any bugfix yet!
Here's what it's all about:
It seems if you use the (custom /manual) speed-adjustments and not the preset slider speeds, you will experience (after exporting your movie) annoying bursts of audio from clips that had been set to mude. The strange thing is that you will only experience this audio-bug after exporting, you will NOT experience it in the project playback mode!
Here's what you can do:
Find ALL the clips in your Project that are Speed Adjusted.
Instead of using a "Custom Speed" percentage, use any of the "Preset Speeds"
Preset Speeds on the Slider = 12.5%, 25%, 50%, 100%, 200%, 400%, 800%
Then, export your project as usual.
No more sync issues.
Really hope That Apple will come up with a real BUGFIX soon.
It's a shame that a major bug in a otherwise GREAT PRODUCT, hasen't been fixed yet!
What's wrong with Apple?...this is not one of their finest hours.
Still A BIG fan from Imovie HD,...I'll chance to Imovie 9 when the bugs are finaly fixed!

This is TERRIBLE! I have spent so much time working on this project, and I really don't want to adjust the speed settings to the preset levels, BECAUSE I need to motion of the video to match certain musical points. I can't re-film my video, and I needed this project done TODAY. I made a music video with some kids at summer camp, and today is the last day- the day we were supposed to all watch it together, and now, I've got NOTHING!!!! (Because I can't export it without all those glitches!)
I am MAJORLY DISAPPOINTED on this one. I've made movies in windows movie maker before, and purposely used imovie, because you know, everything on macs is supposed to be better. Well, I guess I was wrong.

Audio stutters in slideshow

Hello All,
I am a newbie with encore, trying to put together a slideshow with audio and subtitles. I used VBR mp3 encoded using iTunes. I rendered this slideshow and checked the preview to find that the audio stutters.
Any idea if encore doesn't like VBR mp3?
BTW, I will be glad if someone could explain what encore did by 'rendering'?
Thanks

In fact, I have most of the collection in VBR mp3 format only but I can still make AIFF files out of the CDs those are with me (and most of the collection is back home with parents)
Is there any way around to work with mp3 files like exporting to wav and using them etc? I am sure there will be a quality loss but is such thing possible?

Audio stuttering in Yosemite iTunes, Mavericks OK

Ever since installing Yosemite, I've noticed a quite annoying problem: stuttering audio. I listen to music a lot and so iTunes has been the app that shows the problem the most. However, it's not as clear-cut as just playing audio on iTunes.
I've been trying experiments over the last few weeks. I've used tools like top and Activity Monitor, trying to determine if something is taxing the CPU for a split-second or not. Unfortunately, I found no concrete evidence of this. It's random, and it's annoying.
I've also quit all apps that could be causing it like Safari. The audio still stutters.
Symptoms: music played on iTunes will randomly stutter for a fraction of a second. Like a hiccup.
Tests:
iTunes with low-quality audio (64kps). Happens sporadically.
iTunes with high-quality audio (24/192, 24/96). Still happens sporadically, but no differently than low-quality audio. I thought maybe higher quality audio was taxing the system.
Music is on an external thunderbolt My Book from Western Digital.
Movies streamed from the same Thunderbolt drive do not have issues.
Music played using Quicktime from the same Thunderbolt drive does not have issues.
Music played using VLC from the same Thunderbold drive has issues, but not as often as playing through iTunes.
Movies and music streamed to my AppleTV do not have problems when played from the same Thunderbolt drive.
YouTube is OK. No stuttering at all.
So, something seems to be happening with iTunes on Yosemite, and sometimes VLC.
As a developer, I have a small partition for OS testing. I put Mavericks on there and copied some albums with high and low quality audio. Not a single stutter. Not one.
So the problem has to be Yosemite. It's obviously the same computer (mid-2011 iMac, 20GB RAM, 3.7 GHz i7).
I have no clue how to solve this problem. At first I thought it was some kind of Thunderbolt issue, but even with the Thunderbolt update it still happens, and doesn't happen at all with Quicktime.
The only wildcard is the strange stuttering I get with VLC but I'm wondering if it's a red herring.
So is it iTunes, or is there something wrong with the Yosemite sound system?
What can I do to check something like this?

Linc,
I had not mentioned I already tried that, but when I tested it a few days ago, nothing came up in Console.
Just now, I tested it again. It looks like some kind of problem between the Alesis Multimix 8 driver and Safari, but when I quit Safari a few weeks ago the problem still occurred. I just tried it now and it didn't happen. I did upgrade the Alesis driver a while ago and I don't remember if I tried the Safari test before or after that.
Regardless, here's the dump. This does NOT happen every time there's a skip. In fact, nothing shows up in the log when there's a skip, but the dump below does show up when Safari is running.

Video/audio Stuttering on Macbook 13

Hi All
I have a mid 2007 Macbook 13 running OS X Lion 10.7.4. all up to date. Initially I had 4G's of ram ( I know it only reads 3 ) now I have it running on only 2.
Problem is video/audio stuttering when running movies. mostly netflix and or connected to a flat screen tv. on wireless or wired connection. but it also happens just running youtube videos or videos that I have on the system mostly in .AVI format. I could be running movies with VLC or quicktime and same ting. I've tried turning every running program off. like firewall, little snitch, sophos AV, etc. after turning them all off I do a restart. I have done permssion repair, checked the disk, run the daily scripts, even downgraded to SL to see if Lion was too much for the system and nothing. of of the 4G's of ram that I have. I swapped them to see if maybe one or 2 of them ware bad. when I install the operating system, I do a clean install. delete partition, format, the whole thing and bring it up to date. not all at one time. disk permissions repaired after each big updated. almost half the time the videos will run ok and than it starts stuttering. when is doing it. not even the mouse responds in those few seconds. is like something is grabbing all the system memory for a few seconds at a time. it has gotten to the point that the system completly frezzes and I get that black translusent window that says the system needs to be restarted.
I have about 40% free HD space.
Any ideas ?
Thanks

Welcome to Apple Support Communities.
The behavior you mention is typical of MacBooks with the GMA 950 video chipset and 64MB VRAM.
The best solution I've found is to quickly pause the video and let the video load completely before watching, IF the website allows it and will preload the content. Not all of them do. Some sites automatically buffer before they begin playing.
Watch in a window rather than full-screen.
Watch content on your MacBook screen rather than a HDTV.
The Safari Extension "ClickToFlash" lets you choose whether to load Flash content at all. It also allows 'preferring' H264/HTML5 web video content when available, and seems to be a bit better than simply defaulting to Flash content for every website.
I have a mid-2007 MacBook 2,1 with 4/3GB RAM. It is the very oldest model capable of supporting Lion. After reading of performance issues with these older systems in these forums, I chose to remain on Snow Leopard rather than upgrading to Lion. Snow Leopard runs most things I do very well in 3GB. Lion really seems to need 4GB and would like 8GB, from what I read here.
You don't mention how fast your internet connection is. A faster internet connection MIGHT help some. A wired Ethernet connection MIGHT offer a bit more throughput than WiFi. Worth trying out, especially if you have a friend with a faster connection where you can try before you pay to upgrade.
Ultimately we're talking about 5-year-old computers. That's "ancient" in computer life cycles, and the best solution (not most cost-effective) is a new(er) Mac. It's not a problem unique to Mac. Old Windows XP systems lack the performance of new hardware running 64-bit Windows 7.
New or recent Refurbs with 4GB or more RAM, faster video chipset, more VRAM, faster clock-speed, Intel "Sandy Bridge" (or "Ivy Bridge" likely coming soon) dual-core or quad-core processor, and, yes, a hefty pricetag to match. Anything else is at best a temporary measure to buy a bit of time (a year, maybe?) until you can purchase a new(er) faster better Mac.

PPro CS4 - half of audio is missing from exported files

Hi all.
I'm currently working on a project in PPro CS4, and by that I mean that I've already completed the project. It was exported and uploaded to youtube for my boss, no problems. Then he asked me to combine the two videos, so I copied the second half of the video and pasted it onto the first half's sequence. The settings I used for the two sequences were the same. When I play the video in PPro everything works fine. When I export the video, however, the audio is missing from the second half of the video (the half I copied). The second half audio is on the same track as the first half of the audio, so the audio levels on the exported video should be exactly the same.
I've been browsing the forums and looking at troubleshooting pages but I still haven't found a solution to the problem. The video is intact; only the second half of the audio is missing. I have no idea why it's doing this or how to fix it.
I'd appreciate any input.
-RD

Yes, if he is exporting one file of video and audio then either the entire track is exported
or only the work area bar is exported for both video and audio. If he is exporting video and audio separately THEN they might be different lengths.
You might right-click the audio for the second section and select Audio to see if it is muted.
Try exporting the audio alone without video, listen to the audio in Windows Medica player and listen if all or only half of it exported. If all of it exported, then that narrows the problem.
You might try creating a new Sequence and pasting the video and audio into the new Sequence (don't just duplicate the sequence, that may just duplicate the problem). Then export and see if that circumvented the problem.
What format are you exporting to?

Audio dissolve problems after export

Hello there.
I have a problem with audio dissolves. If I export the mastermixed file, the is strange and the mixing isn't right. Where I put a audio dissolve in fading in or out the music sometimes is doubled.
In Premiere, everything sounds fine. When I export in ProRes I get these audio problems. Before the update to 8.1 everything went well.
Any ideas?
Best regards,
Florian.
OSX 10.8.5
premiere CC 2014.1

I got it. It's the AME export! If I export the file directly with Premiere I have no strange audio probs but if I export the soundfiles or the program file with Media Encoder 2014.1 the dissolves are really bad...

Audio stutters with WRT54G v7.00.1

Hi all,
Last week I installed the Linksys WRT54G V.7 router. Since then, my audio stutters every 30 sec/minute . Music and movies just freeze for a second, than continue, 'till it happens again. When I disconnect from the router, everything works fine.
My router is also connected to a Xbox 360 (wired) and a Nintendo Wii (wireless, wifi). I've checked the security settings with the router's webutility, I use WPA2 AES, Beacon Interval: 50, Fragmentation Threshold: 2306, RTS Threshold: 2307.
I've tried for days, but nothing works. I have a Sound Blaster Live Value soundcard. Could anyone PLEASE help me?? I'm getting really annoyed. Thanks in advance.
Greetings,
Pater

Oh really? I forgot to mention. The computer having the audio problem has a wired connection with the router. Could it be affected by the wireless antenna's?
But I could try it. Won't this have a negative effect on my wireless connections (Nintendo Wii, Notebook)? Does it matter wether it's the left or right antenna?
I'm not at home at the moment, but tomorrow night I'll try your suggestion. I'll let you know, ok?
Thanks in advance.

Audio stutters in playback

Hello,
After my ibook has been on for a while I get intermittent but fairly consistent stuttering in all audio playback (regardless of app). I'm running 10.2.8 w/classic active but can't seem to narrow it down to a conflict w/any other app. It usually takes some time to occur but once it's there, only a restart will resolve it (until it starts happening again).
I recently switched out my 256mb chip for a 512, but if the ram were the culprit wouldn't it happen right away?
Thanks in advance for any ideas

Thanks for the response and ideas Klaus,
I tried what you suggested but, unfortunately, the problem persisted. I'm fairly certain it's not an issue of inherent speed of my machine or its architecture or the os or version of quicktime. The same machine w/same system, playing the exact same types of mp3 files, has been working without these stutters for a long time, and nothing has changed w/my audio apps or the os. Also, the stuttering occurs on all and any audio app, even ones that I believe don't use quicktime (VLC etc...). This problem started only recently.
My hunch is that it could be a bottleneck of some sort or RAM or cache not letting go of or not flushing unnecessary data, or maybe a conflict w/an another app (though almost none are running when the problem crops up and the ones that are have been in use for a year or so w/out these problems).
So if I take the machine/speed out of the troubleshooting, I'm left to wonder if it could be the new RAM I installed. But, again, the stuttering doesn't happen right away and sometimes takes a day or so of the machine being on to start happening. but once it does, it doesn't go away until a restart.
**If it were faulty RAM, would the problem show up right away?
**Or is it a corrupt preference file somewhere, but, again, wouldn't that cause the problem to show up right away, too?
Thanks again

Premier Pro deletes denoiser effect on part of audio on video when exporting

I am working with a project that has really bad audio. I have edited and used many noise removal tools in Adobe Audition CC and Premier Pro CS6 (Noise remover, EQ, and Denoiser) which had removed the majority of the noise on the audio. However, after exporting this project and playing it in Quicktime, Premier has seemed to discarded these noise removal effects in the first 5 seconds of the video.
To try and resolve this, I cut up the first 5 seconds and applied an additional denoiser effect to see if this would help. However it did not, and Premier completely disregarded all of the sound removal in all of the exported clip.
Does anyone know why it is doing this and how I can resolve this?

I would like to second this.
I used noise removal. My video is multiple different interviews. There are 5 cuts, to five different audio/video clips, each with noise removal effect on them. but, Only on 2 of the cuts, in the final export, for 3 seconds, the noise removal effect seems to "not work" when the clip starts, then it kicks on gently for the remained of the clip. (similar to what Khalil Jammal said, which is why I'm posting this.
Again, the noise removal fails to "start" only on SOME of the cuts/clips in the final export. It kicks on after about 2 or 3 seconds.
This is odd...it's as if the noise removal effect is having trouble communicating with the final export render. I don't get it. For now, i will have to go back to my "old way" of exporting the audio, cleaning it up in my DAW, then importing it back into Premiere.
This is also annoying as I am paying like, $30 a month for Premiere. This does not seem like something we should have to "work around", but rather, Adobe should fix this issue.

Problem with audio sample rate when exporting

I am having an issue with my audio sample rate. For some reason it is set at 8 khz by defualt when I am exporting. This was not an issue until the latest update (2 weeks ago). I'll try and give all the info I can up front. Also I tried customer support...that was a nightmare.
Ok the issue I am addressing is that the audio sample rate when exporting is at 8khz by default. Which to my knowledge has NO relevant use what so ever. Even when I set the file format to h.264 it insists on resetting to 8khz. Even if I manually set everything look at the render queue and click on output module again it changes the sample rate back to 8 khz automatically which I must adjust again. Why can it not just be set at 48000 like every other adobe product is and like it used to be two weeks ago. Does anybody have an answer?

This problem is addressed by the After Effects CC (12.2.1) bug-fix update, which is now available:
http://adobe.ly/AE_CC_1221
Note the part at the end of that page about a crucial update for the Creative Cloud desktop application, which addresses some severe problems with AME, Premiere Pro, and After Effects.

[solved] Strange Audio Issue

I am experiencing a strange audio issue with my Intel-HDA ICH7:
# lspci -v
00:1b.0 Class 0403: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 01)
Subsystem: Hewlett-Packard Company Unknown device 30a5
Flags: bus master, fast devsel, latency 0, IRQ 22
Memory at d2400000 (64-bit, non-prefetchable) [size=16K]
Capabilities: <access>
when I installed Arch linux the first time a mounth ago on this computer, I had a sound problem that was solved in a very strange way.
Everything worked fine until a week or so (I believe from Alsa 1.0.12). Now sometimes sound works and sometimes it doesn't. For example sometime I boot the computer and have no sound, then I reboot it without doing anything, and then sound works.
I have tried messing with the modprobe.conf:
# /etc/modprobe.conf (for v2.6 kernels)
# --- BEGIN: Generated by ALSACONF, do not edit. ---
# --- ALSACONF version 1.0.11 ---
#alias snd-card-0 snd-hda-intel
#alias sound-slot-0 snd-hda-intel
# --- END: Generated by ALSACONF, do not edit. ---
#options snd-hda-intel model=F1734
options snd-hda-intel model=z71v
options snd-hda-intel position_fix=1
but it was useless. If I put back the modules in rc.conf everything is worse: sound doesn't work at all.
A diff between lsmod in a "working boot" and a "without sound boot" showed that the same modules where in kernel memory.
A diff between dmesg showed this difference:
< hda_intel: azx_get_response timeout, switching to single_cmd mode...
was present in the not working boot. This line is absent in a working boot dmesg.
The only way to make the sound card working everytime is to remove the snd* modules load from the boot sequence and load the modules "by hand" after the login.
Any ideas?
PS : If something is unclear due to my poor English please tell my and I'll try to explain it better.

phrakture wrote:snd-hda-intel is screwed up - on my thinkpad I had to go into the bios and enable the modem for sound to work. Oddly enough, the modem was off by default.
Also, mine has no PCM listed, I need to use "front" as my PCM level... not to mention the UI is way off with 'tpb' (if you have a thinkpad)
Yes it's not an Arch Linux related problem: I had problems with Debian (Etch and Sid based distros like ubuntu) too (but there I had no modprobe issue on the init sequence. Maybe is a problem of shared IRQs, but I have to study the existing documentation as I am a newbie). The difference is that Arch is simple enought for me to try something like modprobing "by hand" in the init sequence. PCM seems to work, however the volume is very low and I have found no way to make the mic work. Under Mepis I was able to make it work only if I plugged it in windows xp and then reboot into Linux. But I can't try it with Arch as I have erased the windows partition...
I will try the new kernel, study the documentation and then report. Hoping this will be usefull to others too.
