MPEG-4 Audio Layer (M4B) is the file format that stores audiobooks and podcasts, primarily those that are available on iTunes. The cool thing about this file format is that, unlike MPEG-Audio Layer III (MP3), M4B can store digital bookmarks. This feature allows readers to pause and resume later, just like a physical bookmark in a printed book!

Free Lossless Audio Codec (FLAC) is a file format that shrinks an audio file’s size, which, as the word “lossless” in the name implies, results in no loss in audio quality or original data. FLAC accomplishes this by using an algorithm that compresses the file to approximately 50 to 70 percent of its original size.
The default program for opening a FLAC file is VLC media player. Other details about FLAC include that it is unpatented, permits music reproduction, is compatible with Telephony Application Programming Interface (TAPI), and is not subject to digital rights management (DRM).
