Setting properties
Common Audio Formats
The built-in AIFF File, CAF File, and WAVE File settings use the Common Audio Formats
transcoding format. This format encodes AIFF (Audio Interchange File Format), CAF (Apple Core
Audio Format), or WAVE (Waveform Audio File Format) les. You can also create custom settings
that use the Common Audio Formats 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 settings) to a job, Compressor
analyzes the source media and then automatically assigns the most appropriate setting
properties (based on the setting’s transcoding format and the characteristics of your source
media le). It’s recommended that you use the automatically assigned setting properties.
Setting summary
Displays the setting name and transcoding format, as well as an estimated output le
size. When you add a setting to a job or change the setting’s properties, this summary
automatically updates.
