How to Trim a Waveform for ACX Using the Selection Toolbar in Audacity

In this video I show you how to trim the precise length of room tone that is required by ACX at both the beginning of your recorded waveform and at the end, using the Selection toolbar in Audacity. ACX requires 0.5 to 1 second of room tone at the beginning of your recorded chapter and 1-5 seconds at the end of each chapter. Using the selection toolbar to trim the excess audio gives you a precise way to be consistent with your recordings from chapter-to-chapter while meeting the ACX standard.
