stereo sounds into mono, resample the files, normalize intensity and remove noise. I wrote a couple of Perl scripts that do just this, converting to and from JSON/YAML, and a Praat plugin to do this from the Praat GUI.

Acknowledgments Extract visible intensity contour Intro Show intensity Types. Querying the intensity contour Intro 6.4. Configuring the intensity contour Intro 6.3. You can then expand that Table to include data from the Pitch and Intensity objects (or whatever objects you need).Īlternatively, most (=not all) text-based formats used by Praat are almost YAML, so you could try to convert them and read them as-is into whatever program you want to use later on. This section describes how you can analyse the intensity contour of an existing sound. Peaks in intensity (dB) that are preceded and followed by dips in intensity are considered as potential syllable nuclei. command available for Formant objects, which will create a Table with the formant data. The difference between the measured intensity of the calibration signal in Praat (Boersma & Weenink, 2020) and the measured intensity of the calibration signal from the sound level meter was. To get started, you could use the Down to Table. You could process them within Praat and put the data you want into a Table object with whatever format and structure you want and save it as either a tab or a comma separated file (see my related answer). So it is either sound.tointensity(minimumpitch75, timestepNone) or (sound, 'To Intensity', 75, 0. 'Pitch' is the perceptual correlate of fundamental frequency which is the rate of vibration of the vocal folds (in speech). Praat-specific (you can check them out by using the Save as text file. As Parselmouth is a wrapper around Praat software, the parameters correspond to the ones in Praat. This might be the hardest part, since Praat does not have any standard way to export data, and the data formats that it uses, although they are all text-based, are all very. You'll still need to know some things about the audio you're processing, though, like the likely frequency of the maximum formant you are interested in, or the range within which you estimate the fundamental to be (you might want to look at this plugin with automatic methods for estimating f0 range).Īs for the exporting, what I assume you mean by this is that you want this information to be accessible from a program that is not Praat. Intensity = To Intensity: min_f0, 0, "yes" Assuming that by "all possible data about audio" you only mean fundamental frequency, formant structure and intensity contour (and not, say, spectra, pulses, etc), the easiest way to do this is to generate respectively a Pitch, Formant, and Intensity objects.
