How to Change Volume Levels In Audacity
Audacity is a free audio editing utility that is quickly becoming a poor man's version of Pro Tools. It is filled with many of the most important features in audio recording and comes packed with software extras to further aid creativity. With a little practice, you can soon be turning out really good recordings that cost you nothing at all.
Open Audacity and start making music. Click on the "Record" button to lay down a track. When you are finished, click on the "Stop" button to end the recording process.
Highlight the track by clicking and dragging, or rewind to the beginning, and hit "Edit," "Select" and "Cursor" to end. This will select the entire track.
Use the "DB slider" at the left edge of the screen to control volume. A greater DB level means more sound, and a smaller DB level means a quieter track. Don't be afraid to put the DB slider into the negatives. This simply means that you are diminishing the volume level of the original track. There is also an alternate way to affect volume that should be used if you want to go beyond the levels of the original DB slider in the left corner of the screen.
Highlight the track like you did in Step 3. Now, go to the "Effect" toolbar at the top of the screen and hit "Effect" and "Amplify." This will bring up a new menu. Here, you can manually type in how much you want to alter your DB level.
