Waveforms disappeared

On previously created projects, the audio waveforms are not displaying in the timeline or viewer. I recently migrated from a G5 to a Mac Pro, then I reinstalled FCP studio but the problem persists. However certain projects and certain media seem fine, BIZARRE!

Forgot to mention that I can solve the problem temporarily by deleting the waveform cache but it comes back next time I open the problem.
Ah, some small progress. Wish I knew more about FCP's caching routines but I do know that most caching processes are based on the OS, not necessarily on the application. The call from FCP to empty the cache is apparently being superceded by the OS's desire to maintain it. This can be a permissions issue: a conflict between the permissions granted to the folder by the system.
You know that indecipherable display of Ownership Permissions in the Get Info window? There are dozens of users assigned by the MacOS and if you've got the wrong one on that cache folder, FCP will not be able to talk to it as expected. This cannot be fixed with a simple Repair Permissions routine. Has to be tweaked by hand.
It's a longshot but I've seen weirder things at the permissions level, especially on Macs with multiple user accounts and especially on Macs where the other users have tried to alter settings on shared folders.

  • When I record an audio track, there is a waveform. When I stop recording, the waveform disappears and becomes a straight line. It also disappears from the track edit window. But the sound is there. How can I stop the waveform from disappearing?

    When I record an audio track using Logic Pro X, there is a visible waveform which appears as I record. When I stop recording, the waveform disappears and becomes a straight line. It also disappears from the track edit window. But the sound is still there. How can I stop the waveform from disappearing? And can I do something to view it after it has disappeared? Anyone know the anser?

    In Logic:
    Preferences/Audio Set Recording Delay to 0 <zero>
    This should always be set to zero unless a specific set of circumstances exist and you're audio drivers do not report position correctly.
    On occasion, usually when importing a Logic 9 project, Logic-X randomly changes this to a negative/positive number.  It's actually a bug in Logic, as it should always display the waveform.

  • Waveform disappears in Timeline.

    Why does waveform disappear in the timeline? Can't use automation because i have no timeline reference for peaks and transients. Tried reloading track and re-adding audio from the bin. Using logic exp 9. Thanks for your help.

    This sounds buggy, try rebuilding your preferences.

  • Some audio clips suddenly grayed out, waveform disappeared, not working

    In CS6 on my MacBook Pro, I was all done editing several sequences and exported them via Media Encoder so that I could have video files to upload to the web. When I looked at the final video files that came out, 4 out of the 6 were missing the audio from the A1 track. I went back into the project file and found that the audio seemed to have disappeared from those particular sequences. The waveform no longer appears and it's grayed out. This is very strange since two of my sequences were fine and exported correctly.
    I was able to double click the original audio source files in the project browser and the audio played fine from that. I took a clip from the source file and dragged it into the affected sequence and that particular clip's audio played fine too. The audio files are all .wav format.
    I read other posts about similiar issues. I tried cleaning my media cache database. I also tried deleting preferences using Shift+Command when opening Premiere. I really don't want to have to go back and find all the audio clips and drag them in again!!

    i'm afraid i don't have a useful answer for this one...
    if the POD has level controls of its own (knobs, sliders, whatever), what you're seeing is generally the normal condition:

    perhaps someone else has an idea why this worked before.

  • Why does the waveform disappear after editing in Sound Booth?

    It happens consistently with CS4 on 2 different computers. I right-click the audio track and select Edit in Adobe Sound Booth, and SB opens the audio for editing. I edit the audio, and it updates the audio. I know it does, because when I play back the edited section, it's correct. But the waveform is gone! I tried playing around with the display style -- disable and enable waveform, keyframes, etc. -- but the audio track doesn't display anything. I have to exit out of Premiere and re-start it to see the waveform again.
    Anyone else experience this?
    Also: when editing the audio in SB, is there a way to substitute the PP audio track with a multi-track? I know I can export a multitrack as an .aiff and import it into PP, but I was wondering if there's a way to link it.

    Thanks for responding, but the thread you mentioned seems to be about a mirror-image problem: waveform not appearing in Sound Booth. In my case, SB is working fine and displaying the waveform properly, which is why I posted my question in this forum, instead.
    The problem I'm having is the waveform not appearing in PPro. This doesn't seem to be a case of "it isn't a bug, it's a feature", because exiting and restarting PPro makes the waveform reappear. So it looks like it is a bug. Unless I'm doing something wrong or have a conflict somwhere.
    BTW, I used to use Audition, but it had too many hardware issues and wouldn't run under 64-bit Windows. Have you tried it under Vista x64, or with dynamic links to PPro or After Effects? It seems that PPro, AE and Flash have been designed to work with SB rather than Audition.

  • Audio waveform disappears when opening file to edit but audio still there

    I recorded an interview in AA and saved it. Had the waveforms there when recording, but after saving, I came back in the next day and opened the file to edit it down and I could hear it, but couldn't see the waveforms. Had this happen a couple of years ago and the guy that fixed it then didn't show me how to do it and he is no longer with the company. Any help?

    This may be a problem with the .pk files associated with the audio recordings.  .pk files store a representation of the waveform for fast display in the application and can safely be deleted so that they are re-generated the next time the files are opened in Audition.
    To try resolving this, open the folder that contains your .WAV recordings and look for the .pk files for each.  It will have a much smaller filesize.  Move these files to a different location or to the Recycle Bin (don't delete them just yet in case there's any confusion about which file is which.)  Then relaunch Audition and open the recordings.  It should regenerate the .pk files and you should be back to normal.

  • Guitar Rig 4 Essential - small audio waveform on track

    I just got Guitar Rig 4 Essential and when I record a guitar audio track, the audio waveform on the track is very small, although the output volume on the GR4 plug-in window is good. I am also seeing something weird, when playing back in loop mode ( region is highlighted and loop continuously ) the audio waveform disappears after it is played and reappears again after it comes around on the next pass. None of this happens when recording using the built-in amp and effects in Garageband.
    I am using a Macbook, 0SX 10.6, Presonus Firebox.

    That's not the way to do it. There are several approaches to this:
    Bus Recording:
    Route the Audio track with GR4 inserted to a Bus - set the Outs of that Bus to "No Output" - choose a new audio track and select the Bus as an Input - hit record and play.
    Or just record the dry signal of your guitar and set GR4 up in a Bus and route the dry signal to that Bus. This way you can always change the effects after you've recorded.

  • Audio Waveforms in Timeline

    I'm not sure if this is a bug or a feature.
    I recently had cause to do some quick and dirty audio editing of voiceover announcements. I used the V/O tool to record the announcements and then used that sequence as the source clip for cutting the final sequence. Initially the waveforms displayed in the final sequence, but once the FCP window refreshed (hide FCP then unhide) the waveforms disappeared. They now seem to be gone forever. If I drop a clip (rather than the first sequence) onto the timeline it shows the waveforms, but nothing I do will show waveforms where the first sequence is the source material.
    Can anybody enlighten me?

    We've completed the edit. So I have marked the question answered. Thanks to everybody for their help.
    It is now more a philosophical issue about why such limitations/features exist. It seems to me there is no good reason for not having the waveforms available if you want them. If you don't you can always turn them off.
    I sometimes find it difficult to get my head around some of the things that Apple have done. As I come from a photographic background rather than having formal training in this industry I am often unclear as to whether there is a lack of understanding on my part, or a different paradigm on Apple's. The way the voiceover tool requires you to turn off your video monitor is a case in point. This makes it pretty hard to do ADR.

  • Sending multitrack Project from FCP to STP on another computer doesn't work

    Hello,
    I attempted to search the forums but can't find my specific problem mentioned. I apologize if I overlooked it!
    I am attempting to send a Soundtrack Pro Multitrack Project from Final Cut Pro 6.01 to Soundtrack Pro 2.01 on another computer. When I do, the video comes through fine but the audio fails to transfer over.
    Here's what I did:
    First I open the Final Cut Project, highlight all the clips in the sequence to send and click "Send to Soundtrack Pro MultiTrack Project". I select all options including the "Fully Rendered Video" Option. This project opens up great in Sound Track Pro on the original computer. In Soundtrack Pro I "save as" and make sure I select "Collect Audio Files", "Collect unused audio files", & "Collect Video File". As far as I have read, this should be all I need to make sure all of the audio and video clips transfer together with the STP file.
    However, when I place this folder (including the media files) on a external hard drive and transfer it on to our other computer (set up for audio recording and editing) and open it up in STP I get no audio. The clips visually transfer and all the clip lengths match up with the video, however there is no waveform showing. A straight line at 0db is all that shows up. I check the clips in the bin and they show the same file size as on the first computer. When I select an audio clip and take a look at the actions tab it shows the name of the clip and under it it says "insert silence" (which was not there on the original computer). When I de-select the insert silence the audio still does not play (the straight line on the waveform disappears). I try deleting the "insert silence" action and the same thing happens.
    I have tried doing this operation mulitple ways with the same result. Am I doing something wrong? The only thing I can think of is the file starts out on OSX 10.4.11 and is transfered over to leopard 10.5. I just tried doing the reverse operation (creating the file from the audio computer and sending it to the video computer) and everything works fine. No idea what this means. I need this to work the other way around so I can begin the extremely intensive audio work on this film while our editor continues the video edits so thank you very much for any help that you can lend me. It is greatly appreciated.
    -Matt

    Could be a difference in OS's causing the problem, but I can't say for sure. You could try using the OMF export option instead. I almost guarantee it will work.

  • Amplitude increase when using Soundtrack Pro as external editor

    I am finding that when I use Soundtrack Pro as an external sample editor from within Logic, the subsequent audio in STP is louder by about 7-8dB, and so often clips. The audio region plays normally within the Logic sample editor and if I open it with STP, not going via Logic, it plays normally as well.
    Am I missing something about the 'use external editor' command, or is this a bug?

    I'm glad to hear I'm not making a trivial error - unless we both are of course . Another bug seems to be that the waveform disappears at odd times.
    I think I will persist with STP as it covers some ground better than Logic, though it is a bit thin to be properly regarded as a 'Pro' app in its own right. It definitely rests on the coat-tails of FCP.
    matrixx, what do you use as an external editor instead, if anything?

  • PP CC 2014 and P2 Audio Problem?!?

    I'm having a rather frustrating problem with Premiere Pro Cc 2014 and P2 clips.  If I have an extended clip (over 4 minutes) the audio will suddenly flatline at about that point.  Usually during interviews.  Here is the timeline: 
    I've tried importing through the media browser and sending from Prelude with the same problem each time.  That same clips comes in fine with PP CC.  I just downloaded the update to 2014 and still have the problem.
    Ideas???

    Hi Mark,
    I currently have this same condition on a project I am working on. I have loads of information that may be helpful. Here is the rundown:
    The clip in question runs 6:38;03
    The audio (all four channels) drops out at 5:00;11
    in Premiere Pro the waveform disappears as well at 5:00;11
    in Prelude, the waveform disappears at the same timecode, however the audio still plays.
    The clip was originally imported using Prelude in its original P2 format as well as transcoded to Apple ProRes 4:2:2. The original footage still resides on the P2 card. The clips were also copied over a network to backup storage which is now at another location. I do not know if the condition followed.
    I have imported the P2 clip from my hard drive, the original P2 clip from the card and the ProRes clip from my hard drive using the media browser for all three.
    Both P2 clips drop out at the same time
    The Pro Res clip has all the audio.
    There has been no restarts or project opening closings since discovering the problem. I can maintain the current condition if you would like to use my situation for troubleshooting. Please let me know ASAP so I can plan accordingly.

  • ..\..\Src\AudioRender\AudioPrefetch.cpp-99   error message and what caused it.

    I found that when I zoomed into the sequence a lot using the +- keys, that the error message "..\..\Src\AudioRender\AudioPrefetch.cpp-99" kept jumping out at me. It was the last 3 steps of zooming in or out that brought the error message up on screen - a lot of times. It was only happening in one sequence in a particular project. I tried the suggestions for similar error messages that I found on this forum, but I eventually realised that in this project I had a WMV file (PowerPoint exported as a WMV file) which also had *audio* with it. (All the other sequences have WMV files but without audio.)
    Going to the troublesome sequence and deleting the sound track from the WMV file fixed the problem. Next, I deleted the WMV file and put it back again. No error message. I then dropped the audio level to zero using the yellow line and the problem came back.
    There is one other thing, the PowerPoint WMV file is 30fps and I’m in PAL land, so I interpreted the frame rate to 25fps. (So that PowerPoint transitions and movements etc. are smoother). I re-imported the original 30fps WMV file and put that in the sequence as 30 fps. Lowered the audio level to zero, and zoomed into the sequence. No error messages.
    So it looks like a combination of WMV file, interpreting the footage and lowering the audio level to zero that caused this problem.
    Do I need to post this somewhere so that Adobe gets to see this bug? (OK it is a rather unlikely combination of events.)

    It's not as unlikely as you think. I just ran into the same exact thing. But I don't think it's the WMV.
    I'm using footage from a Canon 5D Mark III shot at 60fps, then interpreted to 23.976 and dropped in a 23.976 timeline. I've also adjusted the volume on some of these clips, but not down to -∞. Since the error is "...AudioRender/AudioPrefetch.cpp-99" it makes sense that this is an audio related issue. I have also noticed that in the timeline, my yellow levels line and waveforms disappear when this error comes up.
    So far I've been able to get around this bug by copying the clips into a new timeline, but this eventually comes back again.
    The one question I have, is are you editing from an external hard drive? I've been editing at work off an external, then backing it up and working off internal drives when I get home. My external drive has been disconnecting itself lately, but it's never been around or at the same time as this error. Thought I'd still check with others though.

  • Final cut x muting a video track?

    what options do you have when right clicking on a video clip in the timeline? can you mute video tracks???

    Mute Audio
    Pulling down the volume fader to mute an audio channel is not the right way to (from a sound engineer point of view). If you had the level set at a specific level then you have to remember that if you want to "unmute" it. The Mute button is the correct way to to. Unfortunately, FPx doesn't have a mixer (yet) so you have to go to the Inspector and uncheck the audio. You will notice that the waveform disappears from the Clip
    Mute Video
    To mute the whole Video (or any Clip), just select the Clip and use Key Command V or the Menu Command "Clip > Disable"
    I cover that in more details in my manual "Final Cut Pro X - How it Works", available on my website:

  • Half of audio missing when importing .avi

    Hi, I am having some trouble with importing avi-files in Premiere Pro 5.5. I searched forum, read and did the troubleshooting guide at the wiki plus searched through the Adobe Premiere Pro Help without any result.
    Today I've been editing for 8 hours and everything worked fine. I imported some clips and used some of them. But then I messed up the bin-structure so I cleared the whole bin and started importing them again. I also deleted the sequence so no clips where in use.
    But now when I try to import the exact same file that worked before, The audio gets out of sync exactly half of the movies length. Like the audio starts in the middle of the clip while the movie starts from the beginning. So half way through the file it gets quiet because the audio ends there.
    I rebooted my laptop and restarted Premiere Pro. Now I've also reinstalled it. The files play fine in Media Player, VLC and Quicktime.
    Thankful for any kind of hints that could solve the problem
    Edit: now there is no sound at all - sometimes.. it kindof differs
    Edit2: now it started working again - although sometimes it works and sometimes it don't.. sooo annoying
    But if any one else gets this problem: restart restart restart restart, ;<

    Thank's a lot for the help and the reading! I got a lot more wiser about codecs and the details behind the file extension.
    I shot the video (and audio ) with a Nikon D300 DSLR.
    Here is the specs of the camera if needed.
    http://www.dpreview.com/news/2009/7/30/nikond300s#specs
    I ran the errored file through G-spot and this is the result. This is currently the only file that isn't working. Before, another file didn't work, but then it started working and now this file isn't working. At this point I imported all the other files into Premiere and they seem to work at the moment.
    Also, there is a red line above the video clips in the timeline even before adding any effects. The project is 25 fps and my videos are 24 fps. I didn't realize until now, hehe. Here is my sequence information.
    Properties
    6_Middagen
    1280 x 720
    00;11;20;05, 25,00 fps
    48000 Hz - Stereo
    Settings
    However I also tried importing and adding the same video clip on a Sequence with the settings
    Editing mode: DSLR
    Timebase: 24.00 fps
    Display format: 24 fps Timecode
    The rest of the settings are the same as in the picture above. This time I didn't get any colored render line. But the audio problem was still there.
    This is my project. You can see the waveform disappearing right after my timeline marker.
    I Googled "Nikon D300s h.264" and got a lot of results saying it does use it. I know my video files didn't work in CS4 before but the Nikon support said they would work fine in future updates of Adobe Premiere Pro. I am using Adobe Premiere CS5.5 though.
    The weird thing is that one file randomly stopped working. Then it started working again and now another file isn't working.

  • Audio & Visual issues after updgrade

    I just got a new Mac Pro, after which, in the SD project I was working on in FCP5 1) the video started showing through the audio windows of the viewer and the audio waveforms disappeared. I updgraded to FCP6 (which I wasn't planning to do until after I completed the project) and downloaded/installed all updates.
    The same thing is happening and at first I assumed this would be a common problem with an easy patch, but I don't see any other post with this issue. yikes.
    Secondly, after upgrading to FCP6, the video looks fine on my monitor, but it looks lower rez on-screen in both the viewer and canvas, not totally low-rez, but slightly pixelating. I checked the sequence settings for the project and all looks the same as it was pre-upgrade.
    Does anyone have an idea of what's going on with the audio waveforms and how to fix it? that is def. my biggest problem at the moment.
    Many thanks in advance for any help and trouble-shooting ideas.

    Wow, this sounds really weird.
    Hm, I think the best solution will be to backup your data and to recover your system, because the update probably has confused your system so much that its making such things.
    In my opinion maybe the only solution, because if you already tried to reinstall the drivers and to set your system to a earlier restore point and nothing happens this seems to be a really weird software problem. And try to avoid some updates. I know how this sounds but I do it too.
    For example: I have 3 Notebooks, 2 with XP and 1 with Vista. On my XP rigs I just have servicepack 2 and its good how it is, works fine and perfect.
    Cheers and nice weekend
