The built-in MP3 File and MP3 for Audio Podcasting settings use
the MP3 transcoding format. This format encodes MP3 files,
which are often used for digital audio players. You can also create
custom settings that use the MP3 transcoding format.
The properties of built-in and custom settings that use this
transcoding format are located in the General inspector and Audio
inspector. These properties are described below.
Important: When you add a setting (or a destination that includes

then automatically assigns the most appropriate setting properties
(based on the setting’s transcoding format and the characteristics
of your source media file). It’s recommended that you use the
automatically assigned setting properties.
