okay bestie, welcome to ch_lab(1), from the General Commands Manual section of your local man pages 💖 she's a lil label-file copy-and-remix machine and honestly? she ate.

🌸 SYNOPSIS 🌸

ch_lab [-S frame spacing] [-start time] [-end time]
       [-ext file extension] [-extract file] [-extend time]
       [-f sample frequency] [-lf sample frequency] [-itype file type]
       [-key key file] [-lablist list of labels] [-length time]
       [-map map file] [-name feature name] [-class class]
       [-o output file] [-otype file type] [-pad high | low]
       [-pos list of labels] [-q timestep] [-range range]
       [-sed sed file] [fl shift time delta] [-style output stype]
       [-vocab vocab file] [-verify] [-nopath] [-base] [-combine]
       [-divide] [-h] input files ...

🦋 DESCRIPTION 🦋

so ch_lab copies from one or more input label files over to an output label file, and along the way she can optionally do a whole bunch of operations. it's giving "glow-up on the way out the door" 💅

the following option flags are recognized:

• -h — print a summary of usage to standard output. short, sweet, iconic.
• -S frame spacing — the frame spacing of the output.
• -start time — start time, in seconds, for label extraction.
• -end time — end time, in seconds, for label extraction.
• -ext file extension — the filename extension to use for multiple output files.
• -extract file — extract a single file from a list of files.
• -extend time — extend the track file by time seconds beyond the label file.
• -f sample frequency — sample frequency of the label file.
• -lf sample frequency — sample frequency for labels.
• -itype file type — type of the input label file: esps, htk, ogi.
• -key key file — key label file.
• -lablist list — list of labels to be considered as blank.
• -length time — length of the track produced, in seconds.
• -map map file — label mapping file.
• -name feature name — eg. Fo Phoneme.
• -class class — name of class defined in op file.
• -o output file — output file name.
• -otype file type — output file type: xmg, ascii, esps, htk.
• -pad high | low — pad with high or low values.
• -pos list — list of labels to be regarded as 'pos'.
• -q timestep — quantize label timings to nearest value. (yes, the original says "nearst" — we keep her exactly as she is, typos and all 🫶)
• -range range — difference between high and low values.
• -sed sed file — perform regex editing using the sed file.
• fl shift time delta — shift the times of the labels. (no dash, bestie, that's just how she is)
• -style output style — output style, e.g. track.
• -vocab file — file containing list of words in vocabulary.
• -verify — check that only labels in the vocab file are in the label file.
• -nopath — ignore pathnames when searching label lists.
• -base — use base filenames for lists of label files.
• -combine — (listed with no description, she's mysterious like that ✨)
• -divide — (same, no description, main character energy only)
