Adding audio comments provides a method for instructors to give verbal feedback when grading electronic documents.  The embedded audio features in Adobe Acrobat Professional allow users to record comments directly into a PDF document.  Instructors would need a license of Adobe Acrobat Professional and a computer microphone to convert files to PDF and record audio.  Students would only need the free version of Acrobat Reader to access the commented files.  For more information about purchasing Adobe Acrobat Professional visit ITS’ Technology Purchases page.
