How it works

Many multicamera sitcoms are performed before an audience, then edited for timing. Producers may sweeten or balance the recorded reaction when takes are combined or when technical resets affect the room’s response.


What people often miss

Single-camera comedies usually omit audience laughter and rely on editing, music, and performance alone. The choice is a production style, not proof that the jokes did or did not work live.
