Multi-Media Format Files (MMFs)
A Multi-Media Format (MMF) file contains audio elements (vocabulary and Caller
Message Recording [CMR]) and/or fax data. An individual message in an MMF file
is called an element. One MMF file will normally contain many elements. A single
MMF actually consists of two files:
• The index file consists of element names, sizes and other attributes organized
by means of Element Access Pointers (or EAPs). The index file has a .mmi
extension.
• The data file contains audio data (audio, fax, Telecommunications Device for
the Deaf [TDD] tones, etc.) and has a .mmd extension.

Anatomy of an MMF File
In the diagram above, each entry in Vocab.mmi points to audio message data in
Vocab.mmd. Together, they constitute an MMF element, which is the entity
comprised by an index/recording pair of data entries. This scheme allows MMF
elements to be accessed randomly (in any order).
How to Create an MMF File
In order to use MMF vocabulary files, empty MMF files must be created into which
vocabulary elements or recorded messages can be stored. This is accomplished with
the mkmf command or with PeriStudio. For information on how to create an MMF
file with PeriStudio, refer to the PeriStudio User’s Guide.
