Here's how to create gradual audio fades in Premiere Pro.
Step 1:
Click the wrench icon at the top left of your timeline and select "Show Audio Keyframes".
Step 2:
Expand your audio track by dragging its bottom edge downward for better visibility.
Step 3:
Press P to enable the pen tool with your audio clip selected.
Step 4:
Click to add keyframes where you want volume changes to begin and end.
Step 5:
Drag keyframes up to increase volume or down to decrease volume.
The line between keyframes creates smooth fade effects for professional audio transitions.
