One method for uploading your audio files is via the Audio Library tray setting under Settings in the left nav bar. The Audio Library is also the only place in the platform that you can delete any of your audio files.
When you first navigate to the Audio Library, you’ll find two tables with two different audio libraries. The Account Audio Files
table is for your account audio library, and the Global Audio Files
table is for your global audio library. To get an overview of the difference between these two libraries, please visit Intro to audio library
Remember, global audio library files come standard with your account and cannot be modified.
To upload a new audio file to your account library, follow the steps below.
