Mistakes are common in the creative process. To help with these Audacity has Undo and History. We will learn to use both. We will also learn how to Amplify sound in Audacity. Nothing to it.

This video tutorial is a combination of both Tutorial 10 and 16. You can see a full list of the available Audacity tutorials at the end of this post.

10 Undo and History

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.

16 How to Amplify Sound in Audacity

Procedure:

An important part of editing sound is making sure that the volume levels are set properly. In an earlier tutorial you learned how to set the Input Volume levels for your recordings. There will be times when you will need to adjust the volume level of your recordings after they have been done or adjust the volume of a sound you imported into Audacity. To adjust the volume we use the Amplify effect.

To use the Amplify effect you first need to select the sound you wish to adjust then you need to go to the EFFECT menu and select AMPLIFY.

When you first open the Amplify window Audacity will automatically analyze the sound you have selected and make a suggestion as to how much Amplification should be applied to make your sound as loud as possible with out clipping. If you feel that this is a good suggestion you can click OK, click PLAY and listen to the result.

If you wish to manually adjust the Amplify effect you can either put a number in the Amplification window or use the slider. By entering in a positive number the volume of the sound will be increase. By entering in a negative number the volume of the sound will be decrease. When you make your selection you can click OK and click play to hear the result.

If you are not happy with your selection you can go to the EDIT menu and select UNDO to return to the original volume level.
