In this video, you will learn how to increase the audio volume for both tracks and individual clips. I will show you in detail how you can achieve this with the audio clip mixer and the audio track mixer.
Moreover, I will show you how you can further increase the volume of the audio by adding some gain to audio clips.
If you do indeed have Adobe Audition, you will also learn how you can start up Audition from within Premiere Pro and manipulate the audio levels from there rather than changing the settings in Premiere Pro itself.
