Garageband sound drops to a mute at the end of editing
I'm a newbie to podcast editing in GarageBand. I've added my intro, I have the music overlay and the outro, but when I add the MP3 audio file (the podcast recording), the sound declines to a mute at the end of the recording. I tried uploading another MP3 audio file for another podcast guest and it did the same thing.
Can anyone help?
