Hi everyone.  I am not compute savvy at all so forgive me.  I created secer multi tracks and then saved them.  When I export them to mp3 the time of the track changes.  For example I got the track in the program at 55 minutes but after export it is 52.  I have no dead air before or after so why does it do that?  Any help?

    But what length does the file actually play for? Does your file show the proper time if you re-open it in Audition?

    Due to the way the audio data is compressed some playback software can report incorrect times, especially if you used VBR (variable bit rate) rather than Constant. This is because they try to calculate the time of the file using the amount of data against included metadata showing the sample rate and bit depth which doesn't always give the correct answer.

      Yes when I open it in Adobe it is right at the 55 minute mark but when I send it in a Dropbox file it is 52 minutes.  So do I export it in a constant format or something?

      As it is just a reporting error it depends how much it matters if Dropbox or any other software report the incorrect length. If you want it to show more accurately then, yes, by all means use CBR instead of VBR. However the file size may increase a bit for similar bit rate settings.
