How can I create a smooth speed ramp effect for audio in Premiere Pro?

To create a smooth speed ramp effect for audio in Premiere Pro, you can use keyframes to adjust the speed of the audio track gradually. Start by selecting the audio clip, then go to the "Effect Controls" panel and enable time remapping. Add keyframes at the points where you want the speed change to occur, and adjust the speed values between the keyframes to create a smooth ramp effect.
