Spotlight 7: Multimedia Devices


Audio: MP3 Players and Voice Recorders

Multimedia includes items that stimulate more than one sense, typically sight, sound, and touch.



MP3 files: Are normally used for music Use a compressed audio format that

does not noticeably reduce the quality of the sound

Can be recorded, stored, and played on a computer, copied legally from CDs that the user paid for, or purchased from the Web



Using MP3 files on a portable player gives users the ability to take their music with them anywhere.

Most MP3 players have solid-state memory and are small for portability.



Digital voice recorders retrieve sounds and store them on a memory chip. Later, the sounds can be used or downloaded to a computer.
