Light Lecture app analytics for December 19

Light lecture is a player of lecture data. Mac app "Light Lecture Recorder" lets you create lectures from a PDF file, audio files that record your voice, gestures such as pointing to important points. Most importantly, the size of the lecture file created is extremely light compared to a video file recording the actual lecture. The content is just a set of PDF file and some audio files. There are no problems with hundreds of students accessing the server at the same time. This player also has the ability to change the playback speed.
