This otherwise works similarly to calling. In general, the easiest way to at least start a script is to do a thing manually once, and after youve done that, in a Praat script window, copy the command history (with ctrl-h) to see what the underlying commands are. You can bypass the template functionality entirely and execute a script by passing its source code as n()'s first argument (a string). The first step is to construct a script that extracts the initial 22 seconds of some specific sound object that is already open. PraatScript.formatArgument(value) takes a JavaScript value and returns a string formatted for use in n(script, cb) (and. run(callback) will use the specified Praat executable instead of the default (which is the path returned by require('praat')).formatArgument(value) runWith('path/to/praat', callback) instead of. toString() or praatScript().toString() works as you'd expect. ) //.run(.)

Of course, since template strings are merely syntactic sugar, you can technically also do the same in ES5, though it won't be as readable: praatScript( (Run with a JavaScript engine that supports ES6 template strings, or use a transpiler like Traceur.) praatScript`Ĭreate Sound as pure tone: "tone", 1, 0, 0.1, 44100, 440, 0.2, 0.01, 0.01Īnd now we can even embed JavaScript expressions directly in our Praat code! praat-script quotes and escapes everything correctly. Since template strings are multi-line, the ES6 version of our static script is already nicer to look at: 'Create Sound as pure tone: "tone", 1, 0, 0.1, 44100, 440, 0.2, 0.01, 0.01' + '\r\n' +īut this module really shines when used along with ES6 tagged template strings. var praatScript = require('praat-script') To demonstrate praat-script, we'll use a simple script that generates a Sound object, plays it and exits. This file documents praat-textgrids version 1.4.0. run() convenience method to function correctly. TEXTSHORT - symbolic name for the short text file format version - module version as string. praat is an optional dependency of praat-script and is required for the. fancyIntroduction to Praat and Praat Scripting. node-praat ( npm install praat) is one easy way to install it in a Node application. To actually run scripts, you will need Praat. Installationĭownload node at and install it, if you haven't already. Let's say I ran an experiment using some software like PsychoPy or E-Prime. You could use these, for example, to dynamically create file names, or to separate a complex string like '01-e-23.wav' into smaller parts. If you do not want to use a second set of looping through arrays to calculate means, the mean can also be calculated via a rolling mean calculation technique that eliminates the need for looping through an array at the end.Generate and run Praat scripts from Node.js. Beyond simply combining strings, Praat has a bunch of really useful functions that we can use to parse and manipulate strings. dir$ = "/home/matt/audio/"Ĭreate Strings as file list: "list", dir$ If you already know how many iterations you’ve done, such as when looping through all the items in a Strings object, it is not necessary to keep track of the length, though. Note that you must keep track of how many elements are in the array in order to be able to calculate the mean, since Praat does not currently provide the ability to get the length of an array.
