I have used Audacity to edit and track mark a 121 minute mix I have created. I recorded the mix in WAV format and used the add label At Selection function. When I try to save the mix with the label format using Export label function I get an error message pop up ‘Cannot export audio to’ my hard drive location which happens to a an external thunderbolt drive.
MacBook pro 2011
Mac OS 10.10.5
Attached to this question is a screen shot of the event. I hope that this is useful.
This will be fixed on Mac in the upcoming 2.1.3 release of Audacity. However, using back or forwards slashes in file names is a bad idea if these files are intended for use on the internet or for people on other systems than Mac.
