Skipping audio

I am having a problem with audio that is inserted into the timeline. The whole movie plays fine, except for music that I insert over the video. It seems to skip, like an old record that gets stuck. Everything was working fine, now it seems to happen everytime I print to tape. Any ideas would be great.
Thanks so much.

I agree Michael... it is best to keep sample rates of audio files and sequence settings the same... but surely it's not the cause of the OP's problem... I often use 44.1kHz audio files on a 48kHz sequence simply because i forget to check rates, re-sample etc... but it never causes me any problems...
If you think it's the reason why her music is 'jumping' and sounding like an old scratched record... fair enough.
Mind you, perhaps her 1.8Ghz G5 can't handle it...? I don't know...
Ok...Kathy, for the sake of argument... yes... resample through QT to 48kHz 16bit AIFF

Skip audio on quiz slide

Hello Captivate Community,
I'm a long time lurker / dabbler finally putting Captivate to use in some "real" projects.
I'm working with a quiz slide and I'm wondering if there is any way to control audio. I'd like the learner to be able to skip audio so I figured I could add a button to hide the audio object but I see that there is no way to add a button to a quiz slide.
Any suggestions?
Thanks,
Rick

Hello Lilybiri,
Thanks for your response. I'm against using the mute button as this is a global setting and would force the learner to unmute for other slides. And I don't think your other suggestion will work for my course flow. My scenario will work like this: Learner arrives at quiz slide and audio plays narrating question and answers. If the learner answers incorrectly they are forwarded to a video remediation. After remediation the learner is returned to the quiz slide to try again. At this point audio plays again and I would like to give the learner an option to skip audio, but I see I am probably out of luck.

Premiere Pro CS5 skipping audio error

Anyone come across this:
When trying to edit an AIFF audio file in the Premiere Pro timeline, the audio skips when playing back,
meaning that after a few seconds it just skips several seconds and starts playing a different part further on in the same AIFF...
The indicator bar does not visually "skip": just moves on steady as it should.
Related to this:
I have a project that was converted from After Effects CS4 to CS5, that shows the following strange behaviour in CS5:
The comps contain layers that consist of AIFF audio files. When doing an audio preview (.) or a RAM preview, the audio does not play the part of the AIFF file that, according to the time-code, it should play. It starts where it should, but then suddenly it skips a few seconds to another part of the AIFF. All that while the red indicator bar suggests it is still playing lineair as it should (the red line does not "skip" to another point.
This leaves me with an unworkable situation, as it is quite unpredictable which part of the audio will play right...
As far as i can tell this behaviour only happens with a converted project (CS4 > CS5) in After Effects.
But when I started a new project in Premiere Pro I got the same skipping audio with a totally new project!
Converted back to CS4 for now.

Mark,
Your observations are probably spot on. I cannot only comment through PrPro 2.0, so changes could certainly have occurred. I do know that CS4 changed a lot, regarding Audio.
In my CS2 Production Studio version, I have had up to 22 Timelines/Sequences and most have had from 6 to 24 Audio Tracks, with a DD 5.1 SS Master Track. I have had zero issues with any Audio dropouts. Now, I have had issues with Playback stopping and at totally random spots, and this has happened with very simple to very complex Sequences, and different spots. Sometimes, this has happened with a fresh boot and Project load, but also after many hours of editing. These halts come and go. I've had them happen a dozen times in a row, only to then disappear in that editing session. I've had sessions that lasted for days, with not one, only to fire up the program, and get 3 halts in a row. That has been my only, even moderately similar experience.
Wish I could comment on later versions, but I cannot.
Thanks for your observations and for reporting,
Hunt

Skipping audio when sent to encore

when i send my project from premeiere all of the sudden it about 15 mins into the video it skips audio over and over please help!!!!

Well, it does not matter how footage was imported into Premiere or what codec was used for audio. The problem is not a big one but it is exists even on SD projects imported from Premiere via dynamic link. When Premiere sequence via Dynamic link is sent to Encore it imports the sequence and conforms the audio separately. But I think it is a glitch, and I have reported that, but there was no fix for CS4, and I hope it will be taken care in CS5.
Here is what happens.
As soon as PPro project is shown in project pallet in Encore select it, and turn on Progress panel, from Window drop down menu, because by default it is off. And you will see Yellow line showing that audio is being conformed. So if you clicked the Build button before the Yellow line is finished, Encore will take the audio at that point of time and stretch it all the way to the end of the file, and it will build a disk, so that's why it will have the skipping effect described in first post.
After Audio is being transcoded you cant do anything about it until, in the project window you Right click on the asset (asset is being a Premiere sequence) and select transcode setting Revert to original. Encore at that point will start conforming process again and you if wait till it finished it should be just fine after Encore finiches yor disk or folder.
It is inconvenient but that's how you work around it.

How to skip audio bytes from AudioInputStream??

Hi all,
I am trying to write a web application to analyze the frequency spectrum of an audio file. The user has a field of a html-form to enter the time point, that he wants to analyze. According to the user input the frequency spectrum will be analyzed. The current position of the audio file should be calculated first according to this time point. And then the samples after this position from the Audio will be read and then be gathered into an Array. At the end they will be transformed with FFT.
My problem ist that i must read the samples from the first byte of the AudioInputStream (using the read-Method of the AudioInputStream) by every analyze, until the position has been reached. For a long audio file and wenn the user wants to analyze the spectrum of the end of the file, it will take so much time!!
Does anyone know, how can i directly skip the samples before the position and begin the Gathering immediately? the skip-Method of AudioInputStream doesn't work fine! it can't skip to the position correctly.
Thanx in Advance

i tried to use this to skip the bytes: Method 1
AudioInputStream stream_in = AudioSystem.getAudioInputStream("c:\\\\a.wav");
byte[] audioBytes = new byte[4096];
int bytesToSkip = 200000 // just for example
int bytesRead = 0;
try {
while ((bytesRead = stream_in.read(audioBytes)) != -1) {
bytesToSkip -= bytesRead;
if (bytesToSkip <= 0) {
}catch (Exception e) {
e.printStackTrace(System.out);
This method takes to much time, if i want to skip to the end of an long audio file.
Then i tried to use skip() method of AudioInputStream: Method 2
AudioInputStream stream_in = AudioSystem.getAudioInputStream("c:\\\\a.wav");
int bytesToSkip = 200000 // just for example
int loops = 100
try {
while (bytesToskip >0 && loops>0) {
bytesToSkip -= stream_in.skip(bytesToSkip);
loops --;
}catch (Exception e) {
e.printStackTrace(System.out);
//the bytes have been skipped and begin with the manipulation:
The problem hier is, that the skip method may end up skipping over much smaller number of bytes, possibly 0.
Can anyone tell me, how can i accelerate the method 1 or how can i fix the skip method in method 2. Or any other options?
Thanx again!!

Need Help with Skipping Audio in Slideshows

I'm trying to burn a simple slideshow with iDVD of about 80 pictures, with an overlay .mp3 playing. I made the slideshow, and during the preview, the audio plays fine. But after I burned it, the mp3 skips slightly while the pictures change.
I initially thought the pix were too big, so I scaled them down from 400 to about 150 KB. But the second one had the same problem.
Is there anything I can do to fix this? It seems like what might be causing it is the page flip transition between pix. Is there any way I can keep the transition and get rid of the skipping? Thanks so much for the help.
I'm trying to finish this project ASAP, so thanks for the urgent response with any suggestions.
MacBook Mac OS X (10.4.6)

The disk image with DVD Player worked flawlessly.
That's what to expect from a burned DVD.
This just keeps getting more weird.
Not to me now that you're providing more info.
Two items of interest:
1.) I then took the DVD to another player in my house and it worked great.
Not all players handle recordable DVDs very well. Especially if they're older than a couple of years. I've had the worst permormance from Toshiba.
2.) The DVDs are DVD-R, Memorex.
TDK and Memorex have BAD track records here.
I recommend a disk image burned to Verbatim DVD-R at 4X or slower using Toast or Disk Utility.
David Pogue also recommends Verbatim on page 356 of his latest book:
iMovie HD & iDVD 6: The Missing Manual
Quoting David: "Cheaper brands don't use the same amount of organic dyes and are more likely to suffer premature deaths."

Skipped audio files when burning disc in iDVD.

I burned a DVD using iDVD version 7.0. The audio files sound perfect on the computer but on the disc there are skipped areas noted in three different audio files. I did try different discs and burned discs on both my laptop and my desktop. I have used this program before but never encountered this problem. Any tips? Thanks

Hi
My notes on this.
No audio on DVD disc.
Most common origin.
1. Imported audio from iTunes.
• In iTunes copy out as an Audio-CD .aiff (Same as played on standard Stereo CD - no .mp3)
• Use this in Your movie project
2. Low - Free Space on Start-up/Boot/Internal/Mac OS Hard disk makes it hard for iMovie to work as intended.
Down to 1.3 GB and it doesn’t work - especially audio don’t migrate over to Media Browser
(iM’08 & 09)
3. Material in iMovie’08 & 09 - Shared to Media Browser and here selected as Large
large.m4v. It silenced out this project in iDVD. By making a slight alteration - provoking it to ask for a new Share/Publish to Media Browser and here selecting 640x480 - and audio was back when a new iDVD project was created including this movie.
Minuscular - - 176x144
Mobile - - - - - 480x360
Medium - - - - 640x480
Large - - - - - - 720x540 960x540
HD - - - - - - - - 1280x720
4. Strange audio formats like .mp3, .avi etc.
• Change them to .aiff. Use an audio editor like Audacity (free)
5. Main audio is set to off in System Preferences - Does this by it self - Don’t know why
Cheque Audio-Out resp. Audio-In
6. Ed Hanna
Had the same problem; some Googling around gave me a kludgy, but effective fix
Downgrade Perian from recent versions back to version 1.0.
That worked for me, and so far I haven't encountered any deficiencies — except it takes more advanced versions of Perian to enable QuickTime to handle subtitles in .srt format — that I have noticed.
7. GarageBand fix.
In this set audio to 44.1 kHz (Klaus1 suggestion)
(if this don’t work try 48 kHz - me guessing)
Before burning the DVD.
• Do a DiskImage (File menu and down)
• Double click on the .img file
• Test it with Apple DVD-player
If it’s OK then make Your DVD.
Burn at x1 speed.... (or x4)
• In iDVD 08 - or - 09
• Burn from DiskImage with Apple’s Disk Utilities application
• OR burn with Roxio Toast™ if You got it
Yours Bengt W

Problem with Skipping Audio in CS5.5

Hi, I recently opened a file in CS5.5 that I created in 5.03. I have a problem with one audio file. It is a music file mp4a that skips as it plays. All the other files are fine. I deleted the file and replaced it, but that file skips. When i play it in itunes or Windows player, it plays fine. Any suggestions. Thanks Roman

Thank you for the replies. What was happening is that the other audio files were being onverted by PPPro. This one was not. I moved the file to the desktop and once again placed it into the project. This time the yellow conversion line on the bottom right corner went to work and it works fine. It was some type of glitch with that one file. Thanks again. Roman

HP Pavilion dv8357ea and skipping audio

I have HP Pavilion dv8357ea Notebook PC with Windows XP Home SP3. (that's dv8000 series)
I have kept my comp up to date and updated even BIOS, but nothing helps. From the very beginning, the audio has been skipping. It has something to do with HDD activity. Streamed audio (f.ex. Spotify) doesn't skip. I know some other HP notebooks have the same problem, but where's the solution?

X200: Everything's skipping, audio, video, mouse motion...Why?

Hello fellow Lenovites!
I'm running Windows XP on a Thinkpad X200. My problem has been going on for about two months but in the last week has shifted from intermittent to constant. The problem is that all audio or visual display stutters or skips at regular intervals. Audio will go silent, video will jump, the cursor will skip if I move it slowly enough across the screen, and when I hold a single keyboard key, the line of letters will pause. Everything pauses or skips at the same rhythm.
Any help detecting or resolving the issue will be appreciated. All I have at the moment is a prominent but mystifying symptom!
Thanks,
Paul
(Edit: 26 March I changed the subject in case that was throwing people off)

Skipping Audio Playback of Raw AVCHD Files in PE7

I get constantly skipping/dropping audio when playing back AVCHD clips in PE7. These are pretty long takes imported from a Canon HF10 camera. The video seems to playback OK with no jitter/judder or dropouts.I have tried reducing the clip to a 3 minute length but audio still skips/drops every 3-5 seconds for a second or so. I rendered/exported a short test clip to a .wmv file and a 780p file and the audio playback is just fine on the rendered clip. I'm using a Vista 32 Dell 730 desktop with 4 gigs ram and 2.6 quadcore processor and all editing on internal Sata drives. I had the Pinnacle studio 12 editing package first but moved to PE7 due to freezes and crashes. Anybody got any ideas? Thanks!

For HD editing in PrPro, Adobe also recommends a RAID 0 (or similar) media disc. Both HD Audio & Video need a fast file transfer rate. Many get by without the RAID, but it has helped many others. Just a thought.
Also, if you have fewer than 3 internal HDD's, and some of the ones that you have are doing multiple duty, like OS/Programs, and then Project/Media/Scratch Disks, the stream can definitely be too slow to get both smooth Audio and Video.
How is your I/O sub-system set up? Number of HDD's, sizes, speed and controller type?

Need help with skipping audio after upgrading to 10.9.1.

Having read the fine print, I now know that I should not have upgraded to 10.9.1 in the middle of a project. So, started with a brand new library/event/project and I am still getting dropped out audio. Video image is fine. When I scrub back and replay a clip, it sometimes plays better but still skips - only in new places.
Tech info: shooting with Canon C-100 converting files through Brosoft MTS (422 HQ - Audio pcm_s161e at 48000hz) using 2010 MacBook Pro with 345gb free on internal with 8gb of RAM and 380gb on Seagate external where files are located.
Any advice would be greatly appreciate. Oh yeah, happy new year....!

With all the updateing of stuff can you confirm which you changed.

IO7 Update and Skipping Audio

When I updated my IOS to the new IOS 7, all of my audio skips. Everything from music to audiobooks. I've updated the software as it is available, but nothing works. Any help would be appreciated. Thanks.

Hi, QuickTimeKirk,
You asked an interesting question, and here are the results;
When I tried to open a file with QuickTime 7.5.5, it opened, and the About box reported that it was indeed QuickTime 7.5.5.
When I tried to open a file with QuickTime 7.6, the QuickTime menu options briefly appeared for 1-2 seconds, and then disappeared. After this, I couldn't find any indication that QuickTime was running, neither by cmd-tabbing nor by looking at the processes in Activity Monitor.
And QuickTime 7.6.4 opens fine, and is listed as the default app for opening this particular audio file.
Here's some more info. I did a Spotlight search on "QuickTime", and it found two versions of the QuickTime app. Version 7.6.4 was in the Applications folder of my system drive, and Version 7.6 was in the Applications folder of a 10.4.11 installation that I have on another partition of the same drive. I found no listing for a 7.5.5 app, but when I looked again at the 7.5.5 About box, I saw the following:
QuickTime Player
Version 7.5.5 (249.24)
Quicktime(tm) Version 7.6.4 (1327.73)

Is this normal, to have two different versions listed for a single instance of QuickTime?
Thanks for your help.

Stuttering and skipping audio, and an accidental QuickTime workaround

Hi,
I've been having periodic problems with skipping and stuttering audio since the 10.5.6 or 10.5.6 update to OS X. Lately, it's become worse. Just about all of the audio on my system, except for Flash, stutters and skips. I visited the Genius bar at the local Apple store yesterday, and he had never seen anything like it, and suggested an archive and install of the OS, which I'm not quite ready to jump to yet. So this morning, I decided to post my problem here, and I thought it would be a good idea to make a recording of my audio problem so people would know exactly what I was talking about. Since this problem also exists in iTunes, I decided to open a QuickTime Audio Recording window while I had a particular audio file playing in iTunes repetitively. So I had the audio file playing, with its stuttering and skipping, and I opened the QuickTime Audio Recording, and waited for another skipping and stuttering occurrence. To my surprise, the skipping and stuttering stopped! I let the same audio file play for about 20 minutes, and it played perfectly. Also, while the QuickTime Audio Recording window was open, all of the other sounds (alert sounds from apps, etc.) played perfectly. When I closed the Audio Recording window, the audio problems came back! So the good news is that I've apparently found a workaround to my problem. The bad news is that I still don't know how to fix it properly. The Apple Genius suggested that I download and reinstall QuickTime, which I did, but that didn't solve the problem. I have a feeling now that this problem is related to QuickTime in some way. I'm wondering if anyone can offer additional suggestions as to a fix for this. When I right-click on an audio file and select the "Open With..." option, among the choices are three QuickTime versions, 7.5.5, 7.6, and 7.6.4, which make me think that there might be leftover components from older versions of QuickTime on my system. Is there any way that I can do a "clean" install of QuickTime that's more thorough than just a download and install?
Thanks,
Ken

Flash player skipping audio when full screening

Hi, whenever I full screen or go out of fullscreen using flash player, youtube or twitch.tv, the audio stops for like 1 second, and then resumes. This is extremely irritating and has caused me to use Chrome for the last few years, even though I like Firefox better. Is this something that is fixable?

This problem is not with firefox, problem can be with some extension.
Press Ctrl+Shift+ A and disable flash player plugin , restart Firefox, then check youtube, if audio still lags.
Firefox had got cisco video codec which is enabled by default. it is HTML 5.
if problem still exist. follow these steps.
Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.
* Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
* Do NOT click the Reset button on the Safe Mode start window
