Soundtrack Pro corrupting audio files during editing

Using S'trackPro 1.1 on both G5s and Mac Pros, I've experienced a recurring issue when editing long audio files (16bit 48Khz aiffs of 60-120 min durations).
Import files directly in Audio File edit mode, usually apply a limiter and/or normalize and save with new file name. I often find as I move around the waveform to preview results, the playback stops responding accurately, playing the wrong part of the file randomly.
Once saved, the file seems to have random "splurts" of audio appear in inappropriate places throughout. For example, a 2 sec "splurt" from the middle of a 120 min file may appear 10 minutes before the end, seemingly at random.
It's odd that I've experienced this on numerous machines, all with quite different specs.
Any suggestions appreciated.

I actually use the 'save as' function that consolidates all the audio clips and move them onto a separate drive. I'm doing a lot of large projects that have more clips than are actually used. Consolidation means I can move and work on another machine. And in the end it's easier to archive this single directory of files. Works for me, especially because sometimes the audio sources are scattered in too many places on my system.

Linking Soundtrack Pro to audio files stored on an external drive

FCP user but using SP for the first time. I have the large sized audio files stored on an external drive which at the moment I can't access from within SP. Just wondering the best way to link to the audio files?

8 bit / corrupted audio files on re-opening a song

See the post below. I'm having this exact problem with the latest version of Logic Pro on my intel mac. Is there a solution for this mentioned somewhere already? Please let me know soon.

"8-bit" Corrupted Audio Files On Reload?
Posted: Aug 18, 2005 10:45 AM
A day after a recording session with my band the other night, I re-opened the song and recieved an error message "What kind of file is this?" and then another... something about the file being "8-bit" and unusable. This is the bass track from a very good session with my band and I'd like to try and recover it. Does anyone know how this happened, how to recover the file, and how to prevent it from happening in the future? Any help would be greatly appreciated.
More info: When opening the file in SoundHack, it says that it is a "Headerless" file. Setting the header to 24 bit linear and saving a copy results in an extremely distorted and unusable file, but you can kind of hear the recording in the background... sped up.

Hello and thanks to all for your replies. Oh and I did in fact copy somebody else's post. Sorry for the confusion.
I had a backup of the song on another disk with which I continued with my mixing. I am not worried about that particular song now. I am just worried that this might happen again.
About my sound/sample library, I just deleted the folders which had corrupted files and copied back from my backup disks.
Dropping corrupted file in a new .lso doesn't work. Haven't tried moving preferences yet but will do. I didn't have a mac before I bought an intel mac.
Can someone explain why this happened in the newest version when this was supposed to have been resolved in an earlier version? Isn't the latest version a cumulative one?
There's one other thing that also happened with me this week. I think it's related:
I had a Logic project open which was set at 96/24 and I had some audio done in it. I tried to open Reason rewired to Logic because I wanted a drum beat from Dr.Rex. Reason was set at 44/16. I tried to open some of the samples from my sound library. The files played just fine but later on when I checked, the folders which I went into looking for that drum beat got corrupted. In fact, it corrupted everything under root folder. It shouldn't have touched my samples at all, right? Why should this happen when I'm trying to just read samples or files?

Corrupt audio file prevents me from opening Logic project file

Hello,
I've been running Logic 8 for a couple years off my MacBook and have never encountered any significant problems of file corruption until recently.
The issue I encountered is this:
I've been producing a lengthy track in an on-going Logic project file for some time and after completing a recording session I saved and started deleting excess track copies to clean up my arrange window. Upon doing so Logic unexpectedly crashed.
After attempting to reopen the project file, it started its normal process of loading its respective audio files, but now it hangs on one particular audio file indefinitely (I'll refer to it as 'audio file x' for ease of reference), freezing and crashing Logic as a result. All of this project file's auto backup files are also incapable of being opened without giving me the same result and crashing Logic.
I have no way of opening this project file and getting at my most recent saved sequence!
I've tried removing this corrupt 'audio file x' from the project's audio folder and dragging it to the desktop, but this had no effect and I still can't open any recent version of the project file.
Older saved copies of the current project file do still open though (most likely because they were saved prior to the corruption caused by this suspect 'audio file x.') When opening an earlier iteration of the project, I get a message '1 invalid audio region found' (I assume referring to the corrupt suspect 'audio file x' that I removed to the desktop) but the project file is still able to open.
I realize I could import the audio files from the most recent version of the crashed file to an older project version and reconstruct things back to the way they were, but it would take me a lot of time and I'm hoping there may be some way to recover the un-openable project file by getting it to stop looking for this corrupted 'audio file x' on startup.
When I click 'show package contents' of the Logic Project file, I notice two items labeled 'displayState' and 'documentData.' From my troubleshooting I've come to the basic understanding that the 'documentData' file contains all the sequence data and settings for its respective Logic Project file.
I think the 'document data' of the unopenable project file in question may be corrupt because whenever I replace it with the 'document data' from an earlier Project file version, the file is able to open. This doesn't do me much good though, because it's document data from an earlier iteration of the project and I need to be able to get at the current sequence I had right before my file crashed.
Is there anyway to open a project file without letting it load its audio files? Or is there anyway I could get inside the 'document data' file to delete the reference/pathway in its audio bin to the corrupt 'audio file x' its hanging on?
Any insights would be greatly appreciated. I'm hoping there's some way I won't have to repeat a couple days worth of work. Thanks for your help!

After further troubleshooting I've realized that the suspicious audio file that prevents the project file from opening is actually not corrupted itself. I can still play the audio file in other media software like Quicktime, etc. with no problem.
This leads me to believe the problem opening the project file lies solely with the corrupted 'documentData' file.
Does anyone have any ideas about how I could somehow open this project file and delete the reference of the troublesome audio file from the project's audio bin?
Well... it really sounds like the project itself is corrupted, that's one of the reasons all project files won't load from a certain point on.
Try this.
Reboot the Mac.
Open the Applications folder and boot Logic from it's icon.
As soon as the Logic Logo/graphic window appears on the screen hold down the control key. You will see a message pop up that says something like "Launch the Core Audio Driver" there will be yes/no choice available... select NO.
Go to the File menu and selct "open" go find your project file and see if it will open. If it does.. delete the audio file in question... however.. I would also look at any plugins you recently installed and are possibly using in this project...this sounds more like a plugin problem rather than an audio file problem, but that's just a gut feeling.
Anyway, if it opens delete whatever you suspect and save under a different name.
Reboot Logic and see if it can load the project.

Premiere Pro CC not sending Audio files to edit on Audition CC

Hey guys so i just Upgraded from CS6 to CC. Before i did PremiereCS6 was sending audio files to AuditionCS6 with no problems. Since yesterday that i upgraded the option is greyed out and i cant do it. Not sure if this is something happening to a lot of people or just me. Any help would be appreciated. Thanks!

Well if anyone stumbles here for the same reasons i posted i finally found a fix that doesnt involve re-install from another thread. here is the answer it works like a charm.
I had this problem and fixed it pretty quick without the need to uninstall and reinstall.
Look for the default .sesx files in your Document/Adobe/Audition/6.0/Session Templates folder (on Windows 7)
There should be a list of preset .sesx files. Right-click one and set its default application as Adobe Audition by using the "open with" option.
Once I did this I double-clicked to open the .sesx files with Audition, closed it, opened Premiere Pro CC and VUAAA-LAAA the button is available and fully functional.
Hope this helps someone!

Why Do The Latest Versions Of Soundtrack and Soundtrack Pro Use .caf Files?

About 3 years ago Soundtrack and Soundtrack Pro started using .caf files instead of .aif ones.
The .caf files appear to take up more space than .aif and of course need rendering before they can be used in FCE/FCP.
So what is the logic behind their use?
I would add that I have skimmed through several articles which claim they have advantages ..... which I can't understand.
I only know that when used normally in FCE/FCP they seem to me a backward step, requiring rendering - almost like using .mp3 but without the space-saving features.

Here's a link from Apple:
http://developer.apple.com/DOCUMENTATION/MusicAudio/Reference/CAFSpec/CAFoverview/CAFoverview.html
It touts "unrestricted file size" as one advantage of CAFs. Has any of us ever exceeded the supposed 4GB limit of AIF files?? This is from the page linked above:
"Whereas AIFF, AIFF-C, and WAV files are limited in size to 4 gigabytes, which might represent as little as 15 minutes of audio, CAF files use 64-bit file offsets, eliminating practical limits. A standard CAF file can hold audio data with a playback duration of hundreds of years."

Soundtrack Pro losing audio!

Has anyone encountered (and please god, fixed) a problem involving Soundtrack Pro 2 actually truncating audio files (.aiff) so that data after a certain point in the track up and vanishes? For example, say a 10:00 audio file get some edits, is saved, then reopened, and voila—the 10:00 is now 05:00, with everything that existed after that point in the track simply gone. I've experienced this several times over the past few days, twice when saving, then reopening the file, and another time after flattening, which was really weird, because the newly flattened file suddenly consisted of only the first half of the file I had just been working on in the editing window. Great feature: Flatten the file and lose half your track. Anyone have anything on this? Thanks in advance.

You'll probably get a better answer if you post this in the Soundtrack Pro forum instead of the Mail and Address Book one

Logic Pro X: Audio file not found?

I have Logic Pro X, and this problem has never occurred before but...
I was mixing one of my songs and everything was perfect, then I made sure to save it.
As I reopened literally 10 seconds later (not sure why I even closed it) it was showing me a message that said "Audio file not found"
At least 12 audio files went missing out of nowhere. It's only the files recorded from Logic that are not found.
I tried to locate them through my Finder but I don't know where my audio files are stored onto my macbook, and it doesn't seem to be in an easily accessible place.
It's just weird because they were all fine just before I closed Logic, then they disappeared.
I checked the audio bin in Logic and they seem to be there but they seem corrupted.
If anyone can help, or at least show me where audio files are stored on your mac from recording through Logic, that may help.
Thank you.

To clarify:
Logic Pro X
I have also experienced this issue as a result of having recording delay set other than zero, and rectified it by returning to 0.
Otherwise,
[Command 8] or
Window > Open Project Audio, select audio files that appear flatline, click 'Audio File' menu at top left, click 'Refresh Overview(s)'.
No way I know of to auto-enable this.

Corrupt audio files

i'm 3 months into cutting a short film and have noticed that every once in a while some of my music tracks (in aif format) seem to get corrupted. The head of the clip is sometimes not accurate. Almost as if it randomly picks up a few notes or seconds into the original piece of media.
Does this happen after multiple dissolves and renders have been added and taken away?
It's a little frustrating as many of my edits are music-driven.
(i.e. the film would be very boring without the time spent on the music cues).

I have the exact same problem and was actually going to post my own forum on this.
I've had issues with .aiff or .wav audio clips mixed with other layers of audio. When the Aif/Wavs are rendered the first time they are usually fine. But usually if a change is made and it needs to render again FCP seems to merge the two render files together; even being visible in the waveform. Other than listening to the cut and hearing a hit in a song that isn't supposed to be there, there's no way of telling it's happened.
It's a huge headache because everything I cut is to music. I wind up having to check each section of music to see if anything funky popped up. The only workaround I've found is to keep old sequences available so I can just paste in the non-corrupted audio.

Soundtrack Pro import AIFF files Work Around

I saved my AIFF Apple audio files from the earlier version of Soundtrack Pro. I dragged an AIFF into Favorites in the Browser lower right side of UI, worked with it, and "Saved As" send to Desktop and it works.
It won't let you export, but you can bring it into Final Cut from the desktop, by Selecting File & Import.

The goal is to make the files accessible to an Avid Media Composer. Turns out that the only format the MC will import is 44.1K AIFF. It doesn't know what to do with Apple lossless. Maybe it can work with WAVs -- I didn't try that. (And you can't drag and drop to import...)
So what I'm doing is using Libra to point iTunes to a library on a firewire drive, and then importing the CDs as AIFFs. This seems to work.
I will then bring the firewire drive to my place of work and import the files into iTunes on the Mac there.
The only question I have now is whether I needed Libra. What happens when you tell iTunes to change the location of the library? Does it read in an existing library and index it, or do you have to re-import?
Thanks to both of you for your help--
Steve

Soundtrack Pro and Audio already altered in Final Cut

I'm just getting my feet wet with Soundtrack Pro. I have a project that was edited in Final Cut Pro, including keyframes to adjust audio levels in specific places in the audio tracks. When the project is sent to Soundtrack Pro, the changes that were made in Final Cut Pro seem to be ignored. Is there something I'm doing wrong here, or are audio alterations made in Final Cut Pro not passed on to Soundtrack Pro? I'm using Soundtrack Pro version 2.0.2 and Final Cut Pro version 6.0.5.
Larry

Hi Lorenzo,
I haven't encountered this problem, however it sounds to me as though the waveform editor is sensing that the incoming signal is too hot & is automatically pulling down the gain to compensate and overcompensating to the point where the audio is barely intelligible.
What I would suggest you try is:
Select All Command (Apple) A then
Shift Command L. This gives you a window that allows you to boost the level. As the signal is so low, try 100%. If the signal is still too low do the same again. The Adjust Amplitude Filters will appear in the Actions List to the left of the Waveform. This is a nondestructive process & each Adjust Amplitude can be toggled on/off by unchecking it so that you can do a before & after comparison.
All the best
Dave

Logic Pro missing audio files and instrument patches

Good morning
Last week I downloaded Logic Pro version 9.1.8 from the App store.
I have downloaded all the additional copntent listed
I am running a brand new IMAC with OSX10.8.2
The instrument choices and patches show up.....
However many of the audio files and instrument patches are missing.
Prerecorded songs can be loaded but...
When I open a logic song (recorded on my prior IMAC) and recorded within Logic Audio 9.0.0, I get consistent messages such as
EXS24 Instrument "Classical piano.exs" Audio file "BDorfer f O d#.aif not found.
This happens with most most of the patches.
Many thanks for your help

The only things missing from the App Store version compared to the Boxed set are the loops and samples that came as part of Soundtrack Pro and those are no longer available..
However, the sample you mentioned is actually part of the GarageBand Library.... Did you install GB too?
If you did so... then... three things..
First, try using FindAnyFile
http://apps.tempel.org/FindAnyFile/
(Download the version on that webpage and not the App Store version)
..and do a search for BDorfer.. (Just that and nothing else) and see if it finds your missing file.
If it doesn't find it.., install GB and try again... (You may need to rebuild Spotlight afterwards as described below)
If it does find it then..
Two.. rebuild GB's Loop index as this fixes all kinds of weird things in Logic... (and yes, i know its loops not samples but it's worth trying based on past experience fixing these kinds of issues)
http://support.apple.com/kb/HT2443?viewlocale=en_US&locale=en_US
and... if that doesn't work..
Three... Have you reindexed Spotlight?
http://osxdaily.com/2012/01/17/rebuild-spotlight-index/
Logic uses Spotlight to find everything it needs.. so that is worth a try too if everything else fails..

Soundtrack Pro + M Audio FireWire Solo = Confusing

Hardware in use:
-Mac Pro
-M-Audio FireWire Solo
Software:
Soundtrack Pro (latest version)
I could save a lot of backstory if the person reading this is already familiar with M-Audio FireWire Solo. It's an external Firewire interface for audio recording. It has two inputs on the front. One XLR (for my microphone) and one 1/4 inch audio in (for the guitar).
My goal is to record on two tracks simultaneously in STP. Right now I am able to do that in Garage Band using the current equipment, but STP gives me more control over the sound, so I want to switch over.
And now, for the problem. When I try recording using STP, there's an error message. The message pops up as soon as I set the "Input" on the "Recording Tab" (this tab is located in the upper right corner on default layout of STP). When I specify that I want, say, "Track 1" to receive audio from "Input Analog 1" (that's what I have channel one linked to), I get this error: "An Unexpected Problem. NSInternalInconsistencyException *-[NSCFArray replaceObjectAtIndex:withObject:]:mutating method sent to immutable object."
I then have an option to quit or click ok. When I click ok, it still doesn't get the signal from that individual input. Basically it's only letting me use multichannel, which puts both guitar and audio on the same track. This is bad because I can't edit them individually. Sorry for all the gibberish I just wanted to put as much specific information as possible.

Alright, you're very close to fully grasping my situation, and I'm really glad you posted the picture. Basically, just under where it says "input" I click & drag it to the M-Audio Multitrack option. But what it should have is "M-audio input 1" and "M-audio input 2" in that same pull-down menu. I tried to bypass this problem by going into preferences and setting the little "1" button for input 1, and "2" for input 2. So far so good. But as soon as I click the 1 or the 2, it gives me the error message listed above.

Soundtrack has no audio files.

Hope someone can help! just finished the visual part of my film in final cut. now i want to add sound effect etc, however when i open soundtrack it has no sounds in there to use. i have seached my hard drive and have the sound files on there (almost 4GB) and can play them from the finder but they are not in Soundtrack.
Anyone help me?
thanks
jeremy

Thanks Dave but I can't find where i would do that. i kinda assumed that there would be something in the dropdown menu that said
"index your files" or something and then you could select the audio files from the finder.
Hope you can help
Cheers!!

Multibridge Pro no audio monitoring during capture

I cannot get audio monitoring during capture, from betacam (component) or dv, I tried everything I can think of, does anybody else is running to the same problem?
(running mac pro, plenty of ram, Os version 10.5.2, decklink software 6.6.2, FCP 6.0.2)
Thanks for any suggestions.

I tried to reboot the multibridge many but to no avail. Regarding the monitoring, I do not really care about monitoring the upload, but I want to be able to log the clip via final cut, and it should work, however it does not.
Also I wanted to know if users of the multibridge have issues with the video levels? I just switch from a HD Decklink card and the difference in level is not right, the multibridge is much to bright. Any suggestions?
