Here are some of the Praat scripts from my own collection. I will be updating this repository as soon as I have something new to add.
Opening and Saving Files
open_all: its main purpose is to open all objects in Objects' window.
save_raw: saves all sound files in object's window as raw 16-bit little-endian files.
save_all: saves all objects in the object window.
View and Edit Files
view_edit_all: This script opens all wav files in the Praat Objects' window. If you want to open the files with their associated TextGrid, I have found this script created by Pauline Welby extremely useful.
