How are audio clips affected by tempo changes on a tick-based track Without Elastic Audio? With Elastic Audio?

• A. Without Elastic Audio, start times are preserved; With Elastic Audio, clips stretch to tempo.
• B. Without Elastic Audio, clips stretch; With Elastic, start times are preserved.
• C. Both cases, clips stretch to tempo.
• D. Both cases, start times are preserved; tempo has no effect.

Answer: (A)

On a tick-based timeline, tempo changes redefine how bars and beats map to real time, so whether a clip is re-timed depends on Elastic Audio. Without Elastic Audio, audio clips stay exactly as recorded. Their start positions on the timeline stay fixed, so the clips don’t re-time to the new tempo. The grid will shift to reflect the tempo change, but the clip’s playback length isn’t altered by the tempo change itself. With Elastic Audio, Pro Tools time-stretches or compresses the clips to fit the new tempo. The clip’s duration on the timeline is adjusted so it spans the appropriate number of beats or bars at the new tempo, effectively conforming to the tempo change.
