![]() Choose the given recording file on the left-hand side of Praat objects and click the "Draw" button.Click in an area of the Praat "Picture window" (e.g., left upper corner) and draw the new shape while keeping the left-mouse button pressed. Determine the physical size of the plot by changing the selection in the Praat "Picture window" (pink rectangular shape) before you draw the graph.If you accidentally closed it, you can just reopen Praat. You can draw a picture in Praat by the following steps: The standard way to print that spectrogram on paper, or to save it as an image file for inclusion in a report or presentation, is to transfer it to the Picture window with the " Draw" function from the Objects window. However, if you want to create and annotate publication quality graphs, more efforts are required. The easiest way to save a Praat picture is to take a screenshot of it. To play the selected part of the sound, you only need to click on the rectangle below it. You can find the total duration of the recordings at the bottom and the duration of your selected part below the spectrum. If you want to cut, copy, and paste between the sounds, you can open more than one sound, and then select "cut", "copy", and "paste" between the sounds by moving a selected part of the sound to another location, and using "cut" and "paste" from the "Edit" menu. ![]() You can move the red dash line to change the scope of recording. Remarks: Only when you select a part of the recording, all the functions in the pull-down menu can be activated, or they are grey and unavailable. Reverse selection: reverse the selected part of the sound.Set selection to zero: set the selected samples to zero.Paste: paste the clipboard contents to the cursor.Copy selection: copy the selection to the clipboard.Cut: cut the selection to the clipboard.On the pull-down menu of Edit, you can find the following functions The new "Editor window", which has been introduced in detail in 1.2.3 b, will appear. You can start by selecting the speech object and then choosing "View&Edit" from the main menu on the right-hand side of the "Objects window". It is simpler to use the Stereo recorder in Praat and take the best channel.Praat offers a lot functions to visualize, play and extract information from a sound object. Whenever we want to use aįormula on a sound we can think about a sound as a matrix.īut make sure you have something to gain from merging the channels into one mono signal. Each matrix cell contains one sample value. A stereo sound is therefore a matrix with two rows and both rows have the same A stereo sound is a sound with two channels, each channel is represented in one row A mono sound is a matrix with only one row and manyĬolumns. all mono or all stereo) and the same sampling frequency.īefore we go on, we repeat that a sound is represented in Praat as a matrix which means that But all sound files must have the same number of channels (i.e. You can also use AIFF files, in which case stimulusFileNameTail would probably be ".aiff", or any other type of sound file that Praat supports. Simultaneous recording of a speech and EGG signal. The latter option,įor example, can be used to digitize the stereo output signal of the EG-2 PCĮlectroglottograph from Glottal Enterprises Recordings, you obviously have to use “Record stereo Sound’. Purpose you can select 'Record mono Sound.'. In most cases, you will record a single speech or voice sample and for that PRAAT also has the capability to record in stereo, but when it comes to gathering language data, mono files are preferred. In the menu bar of the Objects window, click NEW and RECORD MONO SOUND. Duplicating mono audio into both ears isn't quite the same as reducing stereo audio to mono audio. It also appears that Praat can't work with multiple files when they aren't all mono or all stereo, so that might also be a reason to use mono audio. This link mentions that some occupations involving emergency communication make use of different audio in each ear to get more information across at the same time, but that's as close of a resource as I can find concerning stereo uses of language. I don't know of any human language that depends on stereo audio in order to communicate meaningful information. You want to record audio once, but also want to choose the better half of the audio after your recording is done.Īlso, note that human language is pretty much produced as a mono signal. Having both the audio and the electroglottograph data on one file as "stereo" audio keeps your data tidy. You want to record simultaneous electroglottograph data. However, a few of the sources note some of the times when you'd want to use stereo audio. The consensus seems to be that mono audio saves space, like you said. I've gathered a bunch of sources that marginally comment on whether to use mono or stereo audio.
