This Activity draws a picture of the sound heard by the laptop microphone or the signal present on the microphine socket. More specifically it draws a graph of this input versus time, the input on the vertical axis, time on the horizontal axis. The laptop functions like a machine called an oscilloscope. As well as graphing signal as a function of time, it can also graph as a function of frequency. |

The XO-1 laptop is only capable of mono input, the XO-1.5 and XO-1.75 have stereo input on the microphone socket and can graph two signals at once. |
