I mixed a session from Audition CS6 and the resulting 5.1 .mov file has a gap in it that is nearly a half second long. The source files for the mix are fine at the same place and there are no effects or key frames in use at the point where the problem occurs. This is a long project that runs over 2hrs and 4 mins. if that matters. Has anyone else experienced this? You may wonder why I chose .mov for the mixdown. It's because .wav will not import into Premiere CS6! It would be nice if Adobe's products would work with files created by their other products. In this case Premiere gets an import failure error and says there is a header error.
Unless you're using some odd permutation of the wave format when you export from Audition, that the wav isn't importing into Premiere is definitely a bug. I would encourage you post this at the Premiere forum and/or submit a bug report to them.
Meanwhile, are you on a 32-bit or 64-bit OS? Tell us a little more about your computer. Could be RAM-usage related.
This particular problem happens when exporting to .mov format in 5.1 channel surround. I'm on 64 bit Windows 7 Ultimate. My system is dual quad core Xeon processors with 16GB of ram. The project is long form being just over 2 hrs. The gap occurs at about 1hr 4mins. I can time select the section where the gap occurs and export just that part and it exports without the gap in the results. When I try the same project exported as a wav file, Premiere produces a header error and the import fails. I never actually get to see if there is a gap in the wav file since it won't import.

Ryclark's question is right on, but I wanted to mention that the computer/RAM ought not to be the problem (although you could always put up the system monitor while exporting to verify that) -- that's a pretty decent computer.
The file for the final mix is 48k in 24bit and a little over 8GB is size. Shouldn't be a problem for Win 7 64bit OS. My suspicion is that it was a buffer miscalculation. I will probably try using the export by time selection to create files that don't span as much time and see how that works. I've long since given up on reporting things to Adobe. Rather than try and reproduce the error, they seem to just wear you down with questions and busy work like uninstalling and re-installing applications so that the ball is always back in your court. Eventually you give up and they just close the case. Volia! Problem fixed.

.wav files are limited to a maximum of 2GB regardless of operating system due to the 32bit addressing of the format. Don't know if the same applies to .mov audio files. .W64 are basically PCM files similar to .wav that get round the size limit.
Actually I think that limit's 4GB, same as the RAM limitation, although over 2GB isn't officially approved. Broadcast wav files use a different addressing style in the headers, and don't have this limitation.
The .wav file I tried will open and play just fine in Audition, it's just Premiere that won't load it. It does not have the gap that the .mov file has either. As far as I can see there are no issues with file size. If there are, they are specific to Premiere.

Audition CS 6 has what's called RF64 file support for greater-than-4GB files, so it makes perfect sense that the export works great within the program. I can't test this in Premiere CS6 because I dont' have it, but I'd suspect then that it lacks RF64 support. But that would surprise me because it seems like Adobe really tries to make an effort for import/export options to be consistent.
Same Problem here and it even get worse!
-> Task: Import a feature 5.1 Audio mix from Audition CS6 into Premiere CS6 (resulting audio file is > 4GB)
1. Export the feature 5.1 mix as 48KHz 24Bit 5.1 RF64 Broadcast WAV --> File is valid but Premeiere can't import RF64 Broadcast WAV (Error on import: unknown header)
2. Export the feature 5.1 mix as 48KHz 24Bit PCM MOV --> Every Audition export >4GB results in a corrupted MOV file with audio glitches at the same position.
RF64 Broadcast WAV & PCM MOV are the only file Formats supporting larger than 4GB audio.
The attempt to import a mixdown Audition XML into Premiere failed because Audition creates RF64 Broadcast WAV that Premiere doesn't read.
-> My Config: Win7 X64, CS6 (all current Updates), Corei7, 12GB Ram
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
-> Task: Export WAV uncompressed 5.1 48KHz 24Bit from a 5.1 Adobe Premiere sequence
-> Result: "Error compiling Movie: Unknown Error"
That has worked in the past with CS5.5
--> If I export as 16bit from Premiere it will work but that doesn't help because I need at least a 24bit export...
Whats going on there??
it seems to be like this:
1. Adobe Audition works well with RF64 Broadcast WAV larger 4GB.
2. Adobe Audition renders Audio Glitches into all PCM MOV files larger 4GB
3. Adobe Premiere doesn't work with RF64 Broadcast WAV
4. Adobe Premiere renders PCM MOV files larger 4GB well.
Hmm workflow between Audition & Premiere?
Is anybody out there with a solution how to deal with such situations where you have to handle large 5.1 mixes?
Instead of importing one wav file back into Premeiere I've exported discrete channels from Audition and setup a new 5.1 mix in Premeiere - doesn't like this because you easily can set something wrong and I only have to insert the final 5.1 mix from the sound studio without changing anything.
Then I have to export a audio only PCM MOV from Premeiere to open it again in Audion change bitdeep to 24bit again - and export the needed 5.1 broadcast wav channels.
It's a bit overcoplicated I feel...
Testcase for corrupt Audition MOV export...
please check this out and confirm if it's working right or wrong with your setup:
1. Create a empty 5.1 Audtion soundfile larger 4GB with flatline waveform. (so you better see the glitches)
2. "Save as" audio only MOV PCM 5.1 32Bit
3. close the file and reopen it.
4. Check for audio peaks in the waveform.
Every time I export a > 4GB audio MOV I get random peaks in the exported file. (you have to close und reopen to see it)
Here is a 150KB PNG screenshot to illustrate the effect:
Thanks for the steps. I was able to reproduce the issue with these steps and have submitted a bug report. As this export path relies upon Quicktime, I'll need to wait for a developer to step through and see if the bad data is being generated by Audition or Quicktime.
@_durin_: found also audio spikes in >4GB 5.1 Premiere exports to MOV audio only - uncompressed 5.1 - 48KHz - at all bit deep's incl. 32bit float...
so this realy seems to be a Quicktime thing... :-(
my config: Win7 X64, CS6 all patches, Quicktime: v7.7.2 (1680.56)
--> The audio spikes don't appear if Premiere is exporting Video+Audio - but with audio only MOV export we have the same behaviour like in Audition.
edit: 2012-06-06 - not - also video+audio has corrupt audio peaks :-(
