When exporting one long track made up of parts of individual songs, the timing of the transitions, and the total track length, shifts by as much as 2 mins (increases). I am not hearing any silences and if I load the exported MP3 back into Audacity it is the correct length and the transitions occur at the appropriate time.
I am trying to find where the extra music is coming from but wanted to check if there is an issue with the timestamps on audacity.
I am using Audacity 2.1.2 on Windows 7. When I play the track in windows media player it shows the correct track length but continues playing for 1.5-2 mins.
Thank you for any help available. I couldn’t find anything in the search function that sounds like what is happening so assume I am doing something wrong.
No, but there are issues in Windows Media Player. When playing a “variable bit rate” (VBR) MP3, Windows Media Player frequently displays the time incorrectly. As far as I’m aware it is only a display problem - that is, it plays at the correct speed but gets the time display wrong. Windows Media Player has had this problem for ‘many’ years and Microsoft have shown no interest in fixing it. To work around the problem, either use a different format or a better media player. If you specifically want MP3 and want it to display the correct time, you could use “constant bit rate” (CBR) MP3. The MP3 settings are in the file export dialog screen (http://manual.audacityteam.org/man/file_export_dialog.html)
Thank you for the response, clearly I am a noob. The bigger issue was that I was trying to get one MP3 to use for a picasa slide show with transitions at certain slides. The transitions were not behaving after exporting.
I tried using the CBR option when exporting and it seems to have solved the issue. Apologies if I fall into the 9/10 questions due to my inability to search.
Thank you again for the help.

I thought these issues were fixed in LAME, but maybe something goes wrong when combining files.
