This standard specifies the mapping of A-law coded audio into a sound essence track of the MXF generic container. A-law coding is a sample-by-sample coding defined by ITU G-711 and used throughout the audio transmission chain.

The MXF generic container is the native essence container of the material exchange format (MXF) file body. The MXF generic container is defined for the interchange of streamable audio-visual material.

This standard defines the data structure at the signal interfaces of networks or storage media. This standard does not define internal storage formats for MXF compliant devices.
