# This script saves each interval in the selected IntervalTier of a TextGrid to a separate WAV sound file.
# The source sound must be a LongSound object, and both the TextGrid and
# the LongSound must have identical names and they have to be selected
# before running the script.
# Files are named with the corresponding interval labels (plus a running index number when necessary).
#
# NOTE: You have to take care yourself that the interval labels do not contain forbidden characters!!!!

form Save intervals to small WAV sound files
comment Which IntervalTier in this TextGrid would you like to process?
integer Tier 2
comment Starting and ending at which interval?
integer Start_from 1
integer End_at_(0=last) 0
boolean Exclude_empty_labels 1
boolean Exclude_intervals_labeled_as_xxx 1
boolean Exclude_intervals_starting_with_dot_(.) 1
comment Give a small margin for the files if you like:
positive Margin_(seconds) 0.01
comment Give the folder where to save the sound files:
sentence Folder /home/lennes/tmp/
comment Give an optional prefix for all filenames:
sentence Prefix TMP_
comment Give an optional suffix for all filenames (.wav will be added anyway):
sentence Suffix
