Audio on the multimedia compact discs available today is generally of very poor quality, leaving the general public somewhat confused as they have always been told that compact discs gave 'perfect sound forever'. The average consumer has no knowledge of data transfer rates or downsampling; all he knows is that the CD-ROM he has just paid a considerable sum of money for sounds nothing like the Dire Straits CD he bought last week (and for which he probably paid less than half the price of the CD-ROM). This presentation, rather than delving too deeply into the theory of why the audio on a CD-ROM can sound so bad, instead gives some practical examples of the way in which multimedia CDs are typically authored, and how the maximum benefit can be gained from the limited data capacity available.
