Sweetening sound with audio effects

For most projects, you will probably be happy to use audio in its original, unaltered state, but at some point you might want to start applying effects. If you use music from old cassette tapes, you can use the DeNoiser audio effect to detect and remove tape hiss automatically. If you record musicians or singers in a studio, you can make it sound like they were in an auditorium or a cathedral by adding the Reverb effect. You can also use Delay to add an echo, DeEsser to remove sibilance, and Bass to deepen an announcer’s voice.

You’ll try a few audio effects in this lesson, but you can expand your knowledge by going beyond that. Experiment. Listen to the possibilities. Test some effects not covered here. Each effect is nondestructive—that is, it does not change the original audio clip. You can add any number of effects to a single clip, change parameters, and then delete those effects and start over.
