1 | Balance adjusts the overall balance, left or right. Channel Volume enables you to adjust the volume of each channel individually. You can also use the Audio Mixer's Left/Right Pan knob. Or use clip or track keyframes on the Timeline. |
2 | Check Edit > Preferences > Audio and make sure the 5.1 Mixdown includes all channels. |
3 | Delay creates a distinct, single echo that can repeat and gradually fade. Reverb creates a mix of echoes to simulate a room. It has multiple parameters that take the hard edge off the echo that you hear in the Delay effect. |
4 | One way is to use PitchShifter, select its Cartoon Mouse preset, and apply Bypass keyframes to turn it on and off. |
5 | The easiest way is to create a submix track, assign those three tracks to that submix track and apply the effect to the submix. |
6 | Listen and watch as your audio plays. You'll spot coughs and clicks by their distinctive sharp peaks. Draw a lasso around the part you want to remove and double-click Repair Transient (from the Favorites folder). |
