/** @name Making multiple tracks into a single track
If multiple input files are specified, by default they are concatenated into
the output file.
<para>
<screen>
$ ch_track kdt_010.tr kdt_011.tr kdt_012.tr kdt_013.tr -o out.tr
</screen>
</para>
<para>
In the above example, 4 multi channel input files are converted to
one single channel output file. Multi-channel tracks can
concatenated provided they all have the same number of input channels.
</para><para>
Multiple input files can be made into a multi-channel output file by
using the -pc option:
</para><para>
<screen>
$ ch_track kdt_010.tr kdt_011.tr kdt_012.tr kdt_013.tr -o -pc longest out.tr
</screen>
</para>
<para>
The argument to -pc can either be longest, in which the output
track is the length of the longest input file, or first in which it
is the length of the first input file.
*/
//@{
//@}
/** @name Extracting channels from multi-channel tracks
The -c option is used to specify channels which should be extracted
from the input. If the input is a 4 channel track,
</para><para>
<screen>
$ ch_track kdt_m.tr -o a.tr -c "0 2"
</screen>
</para>
<para>
will extract the 0th and 2nd channel (counting starts from 0). The
argument to -c can be either a single number of a list of numbers
(wrapped in quotes).
*/
//@{
//@}
/** @name Extracting of a single region from a track
There are several ways of extracting a region of a track. The
simplest way is by using the start, end, to and from commands to
delimit a sub portion of the input track. For example
</para><para>
<screen>
$ ch_track kdt_010.tr -o small.tr -start 1.45 -end 1.768
</screen>
</para>
<para>
extracts a subtrack starting at 1.45 seconds and extending to 1.768 seconds.
alternatively,
</para><para>
<screen>
$ ch_track kdt_010.tr -o small.tr -from 50 -to 100
</screen>
</para>
<para>
extracts a subtrack starting at 50 frames and extending to 100
frames. Times and frames can be mixed in sub-track extraction. The
output track will have the same number of channels as the input track.
*/
//@{
//@}
/** @name Adding headers and format conversion
It is usually a good idea for all track files to have headers as this
way different files can be handled safely. ch_track provides a means
of adding headers to unheadered files. These files are assumed to
be ascii floats with one channel per line.
The following adds a header to an ascii file.
</para>
<para>
<screen>
$ ch_track kdt_010.atr -o kdt_010.h5.tr -otype est -s 0.01
</screen>
</para>
<para>
ch_track can change the frame shift of a fixed frame file, or convert
a variable frame shift file into a fixed frame shift. At present this
is done with a very crude resampling technique and hence the output
file may suffer from anti-aliasing distortion.</para><para>
Change to a frame spacing of 0.02 seconds:
</para><para>
<screen>
$ ch_track kdt_010.tr -o kdt_010.tr2 -S 0.02
</screen>
