This wiki describes some audio technology and how it is used today. While this is written from the perspective of a person who is blind, I hope to reach not just the blind community, but also educate the sighted community on the importance of audio and how the technology has changed over time. You can read about how the blind work with recording music, high definition audio, and movies that are described for the blind and visually impaired. I have included links to other websites for those who want more information on a certain topic.
