• Resumen

  • When working on an oral history project, my brother recommended that I download a free audio recording and editing program called Audacity®. I have since discovered that it is a fantastic tool for students to visualize sound waves and to understand the meaning of amplitude, frequency, and superposition. This paper describes a collection of demonstrations, most of which require only a computer, a set of speakers, and a projector.
