| MP3:
MP3 is a lossy compression format. It provides a representation of
pulse-code modulation-encoded (PCM) audio data in a much smaller size by
discarding portions that are considered less important to human hearing.
A number of techniques are employed in MP3 to determine which portions
of the audio can be discarded, including psychoacoustics. MP3 audio can
be compressed with different bit rates, providing a range of tradeoffs
between data size and sound quality.
