Carl S Posted October 10, 2011 Share Posted October 10, 2011 I need help. I have never seen this problem before in 4 years. I am sequencing supermassive black hole for Halloween. When I use the play visable screen the vocals start at about the 34.00 mark but when I go to play it from the whole sequence the vocals start at about 32.00. Any ideas or suggestions. I have tried 2 differen computers.Thanks Link to comment Share on other sites More sharing options...

-klb- Posted October 10, 2011 Share Posted October 10, 2011 Your problem is that your MP3 is variable bit rate.. When you ask WMP to start a song 45.5 seconds into a song, it just takes the bit rate (or average bit rate for a variable bit rate file) and multiplies the bit rate by the requested time, and starts playing from there. But when a file is variable bit rate, you may have cases where more bit rate is used late in the file than early, and this introduces these errors. For most uses, it is accurate enough for windows media player. When it counts like it does with LOR, you need absolute positioning accuracy. If you use a constant bit rate file, your timing marks will line up... You can use audacity to re record the file as fixed bit rate MP3.. Link to comment Share on other sites More sharing options...
Richard R Posted October 10, 2011 Share Posted October 10, 2011 How do you save the song as a fixed bit rate in Audacity? Link to comment Share on other sites More sharing options...
-klb- Posted October 10, 2011 Share Posted October 10, 2011 I'm not sure that you still have to download/install LAME separately, but if you don't have a MP3 export option, you will need to add it.http://www.lightorama.com/PDF/Audacity_Lame_128Kbps.pdfI think Audacity/LAME only exports fixed bit rate MP3, unless that is a feature of a newer version.
