The MusTech visualization allows the user to look at the frequency spectrum and the time development of a recorded sound file. There are 3 options that can be chosen under the Now Playing menu and submenus: 22khz full scale (22kHz Spectrum), 12.5kHz full scale (Spectrum Mag 2), and a graph of amplitude versus time (Oscilloscope). The user can make measurements by right-clicking within the windows. The coordinates of the tip of the cursor position appear in the lower left of the window. These exercises will help familiarize the user with features of the visualization.
The following files play sine waves of equal amplitudes.
