For my tutorial, I decided to show how you can amplify a specific section of a clip to sound louder if the envelope tool doesn’t work out. For example, in many instances during my project I ran into the problem that my self-recorded sounds were always much quieter than the ones I got online. They would appear as straight lines, as pictured below.

As you can see the first clip (titled voice) is much quieter (as represented by the straightness of the line) than the second clip (titled radio). In order to hear the voice over the radio it must be amplified. You could just turn down the radio volume and turn up the voice volume, but when more clips get introduced this can lead to problems where the radio is too quiet or the voice is still too quiet. The envelope tool really is of not help either, as there isn’t much to pull up.

The answer then is to amplify. To do this, first highlight the portion of the clip you wish to amplify with the Selection Tool, as pictured below.

Next, go to the Effect tab (3rd from the right) and find the effect titled Amplify, as shown below.

Clicking on the Amplify option will open up the below box prompting you to make changes to the amplification. The only feature in this box you need to worry about is the first box and/or the sliding scale directly below that. These are circled in red.

To amplify the sound, you can either input a greater number into the first box or slide the bar to the right. To do the opposite (aka make the sound quieter) you can input a smaller number into the box or slide the bar to the left. This is shown below.

When you’re done adjusting the values whichever way you please (for the purpose of this tutorial I adjusted my sound to be amplified, so louder) click OK. You can also click Preview to hear the sound and decide on whether it needs to be adjusted further or not. If you amplify the sound, the straight line should appear more jagged, like that of the radio clip, as seen below circled in red.

The sound is now amplified and will be louder!
