Detailed Description

Track maps provide a mapping from symbolic track names to the actual position of the information within a track frame. The symbolic names are defined by the EST_ChannelType enumerated type.

Track maps can be declared statically by code which always uses tracks of a given style, or they can be built at run time as is done by lpc_analysis to record whichinformation the user has requested. Finally they can be constructed by the Track itself from the names of the channels, for instance when a track has just been read in from a file.
