Hi Brad, when you save an Audacity project, the history of changes isn't saved. So if you subsequently open the project, you can't undo changes that were made before it was saved.

To: audacity4blind@xxxxxxxxxxxxx Date: Thursday, 2 January, 2014, 21:04 Hi all, I thought I had my project working great, so I had voice intro tracks followed by song tracks and everything was aligned great. So I saved the project, and exported the project as a wave file. Then I closed Audacity and tried to play the wave file. I was given a warning when I tried to save or export it that it would be rendered down into a two track file. Or something similar to this. I ignored this thinking that this was fine, then when I tried to play the file, it sounds like my voice intro tracks are overlapping each other. I reopened audacity and the same thing happens with my project file. It used to sound great, so my question is is there a way to get into the history of things that you can undo once a file has be closed an reopened. Can I go back to the state before I saved. Maybe what I have to do now is make all these tracks one track. Thanks for any advice.
