You can upload an audio file.
In order to upload a file, you have to click on "Broadcaster" and then "Upload File". Once the file is uploaded, click the three dots near it to see the "Reference Number". Then look up the "Playback Number" on your account dashboard and your pin, and share those with your audience.
When they call in, after they enter the pin, they will be asked for the reference number, which they will enter to hear the specific recording. If you only upload one recording, you don't need the reference number, as pushing pound will play the last file uploaded.
