Macbook Pro Storage -- Audio
I moved most of my MP3 and Audacity files to an external drive and have only 14 audio files in my Mac, which add up to 253 megabytes. However, "About this Mac" shows 60.1G of my storage is used by "audio." What is taking up so big space? My trash bin is empty and so is ~/Library/Caches. How can I eliminate the mysterious "audio" and get more space in my storage?
MacBook Pro (13-inch Late 2011), OS X Mountain Lion (10.8.5)
