Ég er hættur að encoda mp3!

"The problem is that bitrates only speak to the size of the file, not its quality. For example, one could write a compression format that achieves a 256 kbps bitrate by taking only the first 256,000 out of every 1,411,200 bits (18%) in any given second. Although some foolish people might assume a song encoded in this format would sound better than a typical 128 kbps mp3, any listening test would be able to easily prove the inferiority of such a technique."
