I am using Audacity 2.1.1 from DMG on iMac runing OSX 10.7.5
I have been converting old cassettes to digital files and loading them into iTunes without any problems (about 2 dozen so far) however I recently imported a commercially recorded cassette (the import went fine and I saved the unadulterated file without a problem). After this I opened the file and tried to edit it. Each time I tried to apply an effect the segment I was working on disappeared entirely. It came back if I clicked “unedit”. I tried to label the tracks without editing the audio and then save the project and Audacity would not let me save the project with any changes. I then tried simply to export the labeled audio to a file using “export multiple” and got a message saying “unable to export to file”.
That is the main problem.
More info is that after closing that file the same glitches appeared when I tried to edit and export files I had made from personally recorded cassettes. This had not been a problem for 2 dozen previous as noted. So I gave up and shutdown the computer and had dinner. I came back and tried the personally recorded cassette and had no problems. That was last night.
This morning when I tried the commercially recorded cassette, I had all of the same problems. I went to a laptop and tried the personally recorded cassette files and also had no problems. I am reluctant to try the commercially recorded cassette files on the laptop.
Is there some sort of copyright issue that has been digitalized from the cassette that has caused this and maybe I just need to pitch that file or does anyone have a suggestion about something I might be missing? Seems odd that it would affect subsequent files that otherwise are no problem.
Thanks, Jeff
