What spaced repetition does
Spaced repetition schedules review over increasing intervals. Retrieval practice asks you to bring information to mind rather than only rereading it. Both methods turn memory into an active task.
A simple example
After learning a name, close the note and recall it later that day, the next day, and a few days afterward. Adjust the interval when recall becomes easy or difficult.
Where a listening routine may fit
An audio session could be a cue to begin a study block. It should not be described as a substitute for encoding and retrieval practice, which are the activities directly related to the information you want to remember.
