You receive a set of encrypted audio messages from a secret admirer.
Listening to the sounds yields nothing but a headache, but you have a knack
that you would get something intelligible if you plotted each message
as a drawing.
InputThe messages are all stereo .wav files. Each channel carries an incessant beeping sound that varies in pitch. You should draw a 2D plot, using the frequency of the left channel as the X coordinate, and the frequency of the right channel as the Y coordinate. (The frequencies map linearly to euclidean space.)
