Document Summary

Rely on sound to enhance multimedia applications: easily capture the attention of users, facilitate easy learning, set the mood. On the web sound offers: background music, narration, sound effects, record testimonials, educate/presentations webcast, one-way audio offers on-demand radio listening, conferencing. Visualize the sounds as a series of recurring waves called waveform. Volume: the higher the wave the louder the sound. Pitch/frequency: the closer the waves the higher the pitch. Pre-packaged (come with computer), purchased/borrowed, create own (recording program, recording studio for higher quality, electronic instruments captured in midi) Microphone translates movement into electrical signals (analog) then tape recorder translates the waveform from an electrical signal on a wire to a magnetic signal on a tape (analog) Analog-to-digital converter (adc): adc captures a snapshot of the electric voltage on an audio line and represents it as a digital number that can be sent to a computer.
