Using Sound on Your PC
Why Do I Need Sound?
Furthermore, using the standard audio software on your computer, you can:
record speech or music (as "wave files") and embed these sounds in other

play music CDs or MIDI files on your computer (MIDI files are a way of storing
music, especially music created by keyboard instruments)
record, play, and edit pieces of music or sound (stored as wave files)
