I am trying to find a way to blend tracks (cross fade) to put into my movies. At the moment all can achieve is a few seconds of silence before the second track cuts in even if I fade one out and fade the other in… I am using version 2.0.5.
To get a cross-fade or video dissolve requires that both tracks be available at the same time. You can get that with two different Audacity sound tracks, one above the other. Use the Time Shift Tool (two sideways black arrows) to push one track earlier and later with respect to the other (attached). Apply the crossfade to the overlap point.
Audacity will push everything into one single track when you export.
