When I export in order to obtain an mp3 file of my project I use Audio Export and check “MPEG 1 Layer 3 File”. However, from that I get two separate files in my project audio folder - one titled mp3 and one titled mp3-01. Only the mp3-01 is added to the track list.
These files are very different in size, i.e. in the case of the one I have just done : mp3 is 12MB and the info says it is a mp3 file, whereas the mp3-01 is 159MB and is labelled a WAV file. Obviously the one I want (for Soundcloud) is the mp3.
But why are two files produced in the export process?
