What feature allows audio clips to overlap in a DAW?

The ability for audio clips to overlap in a Digital Audio Workstation (DAW) is primarily facilitated by the use of multiple tracks. In a DAW, each track can contain its own audio clips, and when multiple tracks are used, it's possible to place clips on top of one another. This means that different sounds can play simultaneously, creating a richer, more complex audio mix.

By layering different audio clips on separate tracks, a producer can blend various sounds, such as melodies, rhythms, and effects, enhancing the overall composition. This feature is essential for tasks such as creating harmonies, adding backing tracks, or building a fuller sound in music production. While the other options may play roles in audio production, they do not directly enable the overlapping of audio clips like the use of multiple tracks does.
