With respect to the Undo and History functions, it is suggested that instructors evaluate learners through observation. The activity Squirrel requires learners to use the undo feature multiple times as they experiment with various pitch changes. At the time of observation, instructors can also talk with learners about the use of the History function and make evaluations based on the resulting discussions.

Procedure:

Audacity has two functions that allow us to fix mistakes we make – Undo and History.

Undo is a great function if you have just done something in Audacity which was not intended. To reverse this single event you just need to go to the EFFECT menu and select UNDO. There is also a keyboard shortcut for UNDO: On an Apple computer down Command and press Z and on a Windows computer hold down Control and press Z.

Oftentimes we will complete several functions in Audacity only to find that the result is not what we want. In this case Undo will not work for us. History lets us reverse many steps within Audacity.

In Audacity go to the VIEW menu and choose HISTORY. Review the list of events, choose the point in history at which you would like to restore your project and click OK. Your project will now be restored to the point you chose in History.
