Digital Audio

Question 18 • Introduction to Information Technology - EL3701

You are streaming music from an online radio station. Which of the following describes what happens in order for you to listen to the music on your computer? Choose all that apply.

Answer
A
Music is compressed during playback.
B
Music is decompressed during playback.
C
A codec in the media player decompresses the music during playback.
D
A codec in the media player converts the digital audio into analog audio.

Explanation

The streamed music is typically sent in a compressed format to use less data. During playback, it is decompressed, and a codec in the media player handles that decompression. The computer’s audio hardware converts the resulting digital audio into an analog signal for the speakers or headphones, so that conversion is not what the codec does.
