Silly question but if I want to select the first 10 minutes of a project, I put in all zeros in Selection Start, change the button to ‘length’ instead of ‘end’, and put 10 minutes in the second box.
So if I want to select the next ten minutes do I put 00h 10m 00.001 s in the start box and then 20m in the second one, again with length selected?
If it was the only selection you wanted, you could also leave it at “End” - the End is also 10 minutes.
Put 00h 10m 00.000s in Selection Start (just increment the third Start digit). This is equivalent to dragging the selection rightwards from time zero, such that you would drag the selection back on itself.
As another alternative which saves you leaving the track table, you can use [ and ] shortcuts: Audacity Manual.
