Basically I’d like to put the bottom ones onto the end of the longer audio sound. I tried cut/copy and paste but it doesn’t work at all. How can I do this if possible?
In Audacity 1.2.6 there are several major limitations to what you can do regarding moving audio between tracks.
If you upgrade to Audacity 1.3.12 you can just select the audio that you want to move, press Ctrl+X to cut it, click on the track where you want to paste it and press Ctrl+V.
One option is to slide the “EVA Stars” forward in time using “time shift” option:
click on the double headed arrow ( flashing below) then you can slide “ EVA Stars” forward in time so it starts when “PROTO MO…” ends.
You can do this “time shift” on Audacity 1.2. or 1.3
