I recorded over 26 hours worth of DJ sets for a festival stage and saved them as an audacity project file. Now I have come to edit them down into their 1.5 hour segments but am having issues opening the file.
If we cannot figure why 2.1.1 cannot understand the project then as long as you never edited the recording it is possible to make a number of WAV files from the recorded data. See Recovering crashes manually. In your case you would need to make about 30 WAV files (recovering four “d” folders at a time).
