Exported MP3 stops playing after 16 min

[toothdeuce]

I have imported 2 tracks into audacity, both tracks equal a 2 hour runtime BUT for some reason when I export the whole thing as a mp3, it only plays 16 min of the track and then stops. I checked the properties on the mp3 and the length is 2hrs but still won't play pass 16:00 HELP ME PLEASE!!!!!!

What happens if you import the track back into Audacity?
How much free space do you have on your C: drive?

I'm having a similar problem but must also confess that I'm a newbie. However, In my case, I'm working in Win7 (x64) with a 825GB of free space on C: drive (yes, it's a new computer a big C: drive). I have the original digital voice recording of a meeting that is 1.5 hours in length, and my recorder records it in .wma format. I have downloaded the latest FFmpeg (FFmpeg_2009_07_20_for_Audacity_on_Windows.exe) from http://lame.buanzo.com.ar/and installed it.

My original .wma file is 21,029KB in size. After I import this file into Audacity 1.3-Beta (Unicode) and immediately export it as a mp3 file, the new mp3 file is 22,391KB. Both wavforms only show 25 minutes of recording (both imported wma and exported mp3).

When I listen to the original wma file using Windows Media Player, it is complete in playing the 1.5 hour meeting. When I listen to the mp3 file exported from Audacity, it only plays back the first 25 minutes of the meeting. So it seems like Audacity is having a problem with the initial import of the recording, i.e., not importing the entire file, and hence the exported mp3 is not complete. Any help would be greatly appreciated!

ter I import this file into Audacity 1.3-Beta (Unicode)

How long is the track in Audacity before you export it?

[SallieMae]

The initial imported track is 25 minutes so it appears it's exporting what it's getting on the import.

And I presume that the 25 minutes that is imported sounds normal?

It could be a slightly damaged WMA file, and as FFmpeg's WMA support is still experimental it may be less fault tolerant than other converters.
You could try converting the WMA file to a WAV file then import the WAV file into Audacity, using a (free) 3rd party converter such as Super by erightsoft (or other format converting software) to convert from WMA to WAV.
