A DIGITAL AUDIO PLAYER (10) AND A METHOD FOR PROCESSING ENCODED DIGITAL AUDIO DATA, WHEREIN THE DIGITAL AUDIO DATA IS ENCODED USING ONE OF A PLURALITY OF ENCODING FORMATS. THE EXEMPLARY AUDIO DATA PLAYER INCLUDES A HARD DISK OR OTHER DATA STORAGE MEDIUM (32) FOR STORING DATA FILES, A MICROCONTROLLER (22), BUFFER MEMORY (25) FOR ANTI-SKIP PROTECTION, AND AN AUDIO DECODER (12). THE ENCODED AUDIO DATA FILES AND ASSOCIATED DECODER FILES ARE DOWNLOADED FROM A PERSONAL COMPUTER OR SIMILAR DEVICE TO THE AUDIO DATA PLAYER HARD DRIVE. THE PLAYER PROVIDES A MENU-DRIVEN USER INTERFACE (21, 26) FOR SELECTION, SORTING, AND PLAYBACK OF STORED AUDIO DATA FILES. THE AUDIO DECODER, GENERALLY A DIGITAL SIGNAL PROCESSOR, PROVIDES VARIOUS PRESET EQUALIZATION MODES. THE PRESET MODES ARE SPECIFIC TO AUDIO GENRES SUCH AS JAZZ, POP, AND ROCK. THE USER MAY SELECT A SPECIFIC EQUALIZATION MODE BY USING THE USER INTERFACE (21, 26), OR THE PRESET EQUALIZATION MODE WILL BE AUTOMATICALLY SET BASED ON THE GENRE, OR OTHER ATTRIBUTE INFORMATION, INCLUDED IN A TAG PORTION OF THE AUDIO DATA FILE.
