YouTube is a helpful study tool when you need to find multimedia coverage of historical events or hear readings of ancient texts. If there is a video of an important event, such as presidential speech on the White House's YouTube channel, that you want to write about for a class but you only want the audio, you can create an MP3 for listening on your computer or portable audio device.
