emuRtrackdata: emuR track data object

In emuR: Main Package of the EMU Speech Database Management System

emuR track data object

Description

A emuR track data object is the result of get_trackdata if the resultType parameter is set to "emuRtrackdata" or the result of an explicit call to create_emuRtrackdata. Compared to the trackdata object it is a sub-class of a data.frame which is meant to ease integration with other packages for further processing. It can be viewed as an amalgamation of a emuRsegs and a trackdata object as it contains the information stored in both objects.

Format

The data.frame has the following columns:

$sl_rowIdx

column to indicate emuRsegs row index that the value belongs to

$labels - $sampleRate

duplicated information of emuRsegs row entries

$times_rel

relative time stamps of sample values in milliseconds

$times_orig

absolute time stamps of sample values in milliseconds

$T1 - $TN

actual data values (e.g. formant values / F0 values / DFT values / ...)

Note that $labels - $sampleRate as well as $T1 - $TN (where the N in TN is to be read as the n-th T value) refer to multiple columns of the object.

Methods

The following methods are implemented for emuRtrackdata objects:

cut

Function to extract a emuRtrackdata object from an emuRtrackdata at a single time point or between two times
