What is it called when an audio track fades out while a second track replaces it?

• A. Wipe
• B. Fade out
• C. Cross dissolve
• D. Crossfade

Answer: (D)

Crossfade is the seamless blend where one track fades out as another fades in, overlapping in time so both sounds exist together during the transition. This creates a smooth handoff between tracks without any silence or abrupt cut. If you only fade out, you’d end the first track on its own and wait for the second to start, which can feel jarring. Wipe is a visual transition, not used for audio. Cross dissolve is a term more common in video editing; for audio, the standard term is crossfade. You can adjust how long the overlap lasts and the fade curves to make the transition either subtle or more noticeable.
