Output files

After a completed folder analysis the working directory will contain the following folders:

• csvs
• formants
• formants_edited
• formants_winners
• images_comparison
• images_edited
• images_winners
• infos
• infos_aggregated
• processed_data
• regression_infos
• sounds

The folders contain information related to the stage of analysis when they are created. The data created at each analysis step is presented below in this order.

Track formants

File information

A file will be created called 'file_information.csv'. This file will contain information about the sound files being analyzed. If you extracted sounds form a TextGrid using the functions in Fast Track, then this is made for you already. This file contains 5 columns: file number, file name, label, group, and color. The last three are just for plotting. If you set these up to contain colors or IPA labels, Fast Track will use the information in this file to make nice plots for you when the folder analysis finishes.

formants

The formants folder contains the Praat formant analysis objects saves as plain text files. The naming convention is 'filename_N_.Formant' where 'filename' is the name of the wav file being analyzed. The N in the file name correspond to the analysis step, and the extra '_' after the 'N' is just to make my life easier. This folder will contain (total number of files) x (total analysis steps) files so you hay have a lot, but they will usually be tiny (<50 KB).

infos

The info folder contain the log files detailing the analysis carried out for each file. The folder and log files are created not but are updated as the analysis proceeds. The structure of the log files is explained here

Select Formants

images_comparison

The images_comparison folder contains images comparing the analyses for each sound. The naming convention is 'filename_comparison.png'. These files tend to be 1-2 MB each. If you have a large amount of files, (> 2000 ?) you may not want this much data for this analysis. I am going to add a function that generates these after for a subset of analyses. For an explanation of the way the figures should be interpreted, please see this page.

Get Winners

csvs

The csvs folder contains csv files representing the 'winning' analysis in tabular form. Estimated formant frequencies are always written out. These columns are named 'fN' for formant number 'N'. Time, expressed in seconds, is also always written out. The use can select which other information gets written out by selecting the "Set Options" from the Praat window. Then at the bottom of the window select the "CSV output" menu and select "Switch Options". In this option menu you can choose to output or omit:

• formant bandwidths. These are named 'bN' for formant number N.
• predicted formants. These are named 'fNp' for formant number N.
• pitch ('f0').
• intensity.
• harmonicity.
• normalized time (normalized time = (end time - start time) / duration).

The setting determined with respect to csv output are saved in a text files and remembered across sessions.
