+# Sound extractor from PPT files
+
+This is a simple python script to extract embedded audio in ppt files
+and merge them into one file.
+
+* To run this script, open the terminal and cd to the directory where your ppt file lies.
+* Type the command python3 extractSound.py Filename.ppt where Filename is the ppt file that you want to extract its embedded audio.
+* Now, you should find a joinedFile.wav file in the same directory.
