If your digital music collection contains songs recorded or mastered at different volume levels, listening to music on your computer can involve constantly adjusting the volume control. You can use Audacity to make all the songs in your collection play back at the same volume. The process of equalizing volume levels is known as normalization; Audacity includes a built-in "Normalize" effect you can apply to all the songs in your music library.
Step 1
