I am going to break this reply into two sections (getting the job out in time
& figuring out the problem
) because you are under a deadline! You might want to try the first suggestion for "figuring out the problem" and if it does not work skip directly to "getting the job out in time"--once you have the deadline off your back we can do all the tedious stuff of figuring out why you are having the problem!Figuring Out The Problem
1) Though rare, it is possible that your installed version of Audacity &/or libsndfile is ever so slightly mangled. libsndfile is built in to Audacity so your best bet here is to download a new Audacity. You might as well grab the Nightly, it is almost the same as the recent beta release but has a few bug fixes:
Download 1.3.13 (Beta):http://audacityteam.org/download
2) Give us a lot more detail!
___A) Is this happening for everything you try to export?
______i.) We need a lot more detail about the failing audio:
_________a) is it a project which has been saved and now re-opened?
_________b) how many tracks?
_________c) how long (in minutes & seconds)
_________d) have you named any of the track(s) and if so what names?
____________exit Audacity completely, start it with a single empty project window
____________select menu Generate > Noise...
(accept the defaults)
____________try to Export using the same method which is failing--does it export OK?
___B) Is it only WAV exports or all exports?
______i) Try exporting your failing project as an MP3 or one of the other formats; did it export and could you play the result?
___C) You show Audacity 1.3.13 in the original post but to make sure what is the exact build number and date (menu item Help > About Audacity...
______i) Have you installed Windows7 Service Pack 1 (and in general all Windows updates)?Getting The Job Out In Time
1) First, let's try to rehabilitate your project...open it then open a new project window(menu File > New
). Next, for each track, click in the track's waveform, press <HOME> (or whatever your appropriate keyboard shortcut is) to move the cursor to the beginning of the track, press <CTRL + a> to select all, then <CTRL + c> to copy it all; now, in the second (empty at first) project create a new track (mono or stereo as appropriate, menu item Tracks > Add New > Audio Track
), click in this track's empty waveform and paste (<CTRL + v>). It is very important
to follow these steps exactly
as we DO NOT
want to copy the track, just the audio! You should now have a second project window with the same track structure and audio; close the original project window. Now use the menu item File > Open Metadata Editor...
and make sure every entry is EMPTY
. Now, save this as a Project in a new, different directory from anything previously used. Finally, try to export this as a WAV using the method which failed in the past.
If this worked, save this Project in another new, different directory from anything previously used (and maybe also on a CD or somewhere external). If so, go back and add any track names and try exporting again (to a different file name <grin>!), is all OK? If so, add metadata (maybe one or two items at a time)--OK? If so do anything else you need to get the Project & export into shape to submit, export OK? If so wipe sweat off brow, pour a tall cool one sit back and wonder what went wrong with the first project!
2) OK, that did not work; let's try another approach...open the original project and select all the tracks (of course, there may only be one -- menu item Edit > Select > All
). Open the Export dialog-- menu item File > Export...
. Try one of the other WAV export options, here is the most obvious:
others are accessed via the "other uncompressed files" Save as type:
Did anything there export (the 32 bit float will be most usable)? If so and the result is something you may submit, do so (see above for sweat wiping etc.).
3) OK, getting desperate here...as in #2 above, open your Project, select everything, open the Export dialog and try exporting via Save as type:
"other uncompressed files" and use FLAC files:
use the Options...
button to open the Options dialog--select Level 8 (best) and Bit Depth 24 (best) for maximum quality. Did this export? If so (and FLAC is not viable for submission) use any of the available converters to convert this to a WAV and again see above for tall-cool-one etc.).
4) Hair pulling time...! Zip up your Project (use menu item File > Check Dependencies...
and insure your Project is self-contained) post it to a file sharing service and ask a forum elf to inspect the Project.
