change/copy track file
copies an input track file to an output
track file, optionally performing various operations along the way.
The following option flags are recognized:
- Print a short summary of options to standard output.
- Input file type (optional). If no type is specified, type
is automatically derived from the input file's header. The list of
supported types may depend on your particular Speech Tools installation.
For a full listing, see the output of the -h
- Contour type, either F0 (fundamental frequency) or
- Frame spacing of input in seconds, for unheadered input
- Select a subset of channels (starting from 0). Tracks can
have multiple channels. This option specifies a list of channel numbers
which are to be used for processing.
- Extract track starting at this time, specified in
- Extract track ending at this time, specified in
- Extract track starting at this offset, specified in
- Extract track ending at this offset, specified in
- Filename to write output to. Defaults to standard
- Output file type. If unspecified, ascii is assumed. For the
full list of supported types, see the output of the
- Frame spacing of output in seconds. If this is different
from the input spacing, the contour will be resampled.
- Print information about the input file and its headers.
This option gives useful information such as file length, file type, and
channel names. No other actions are taken, and no output file
- File containing new names for output channels
- Differentiate contour. This performs simple numerical
differentiation on the contour by subtracting the amplitude of the current
frame from the amplitude of the next. Although quick, this technique is
crude and not recommended as the estimation of the derivate is done on
only one point.
- Make delta coefficients (better form of differentiation).
The argument to this option is the regression length of the delta
calculation and can be between 2 and 4.
- Length of smoothing window in seconds. Various types of
smoothing are available for tracks. This option specifies length of the
smoothing window which affects the degree of smoothing, i.e. a longer
value means more smoothing.
- Type of smoothing.
- Convert track to another form. Currently only one form,
"label", is supported. This uses a specified cutoff to make a
label file, with two labels, one for above the cutoff (see the
-pos option), and one for below (see the
- Threshold for track to label conversion.
- Name of negative label in track to label conversion.
- Name of positive label in track to label conversion.
- Combind given tracks in parallel. If option is
"longest", pad shorter tracks to longest, else if
"first", pad or cut them as appropriate to match the length of
the first input track.
