A comment from the teacher who created this file:

"Well, I was successful...I thought I had this audacity thing right. I actually recorded it yesterday just as a test recording. Today I tried to fix it--you know so it sounds better, but my microphone for some reason is not picking up anything...so I'm sending it as it is. It's all in French, if you'd like to know what I'm saying I'm pasting it below. This is a poem written by Guillaume Apollinaire--a very famous French poet. Enjoy!"

A message from the teacher who created this file:

"Hello All!
I hope that you are able to access my attempt at an audiobook on The War of the Worlds by H.G. Wells. Our next unit of study is the solar system, so I thought this would be a fun connection. I just read the introduction because I'm still not sure if I'm doing this correctly. Nonetheless, I hope you enjoy the introduction. I MIDIed the soundtrack of the movie as my background -- if you can't hear it, it's because the martians took it.
See you soon,
Gilda"

Dr. Giza's tutorial that he developed for using Audacity for sound narration and enhancement is online at
http://www.educationtechnologies.com/modules/audacity02/slide01.htm

A summary of the process: Students use audacity to record a narration, perhaps saving it in Audacity's AUP format. Then they record or import sound effects to a second or third channel, and mix them together, exporting them in the popular MP3 format.

Audacity is an open-source sound recording and editing product, freely accesible and distributable. It is available for all the major platforms, Apple, (OsX), Windows, and Linux. To export MP3 format files, you must add the LAME encoder plugin, which is also free.
