Method and apparatus for timing of play back files of which audio data digitally coded with a speed of bit variables ".The present invention is a digital audio player (10) and a method for processing digital audio coded data.In which the digital audio data is encoded using one of a plurality of encoding formats.The audio data player has a hard disk or other data storage means (32) for the storage of data files, a microcontroller (22).A buffer memory (25) for protection against jump, and an audio decoder (12).The files of the audio data coded and the associated decoder files are transferred to a personal computer or similar device to the unit rigid - audio data. The player provides a menu driven user interface for selecting, classifying, and play back audio data files stored.During the play back, time to play back time is calculated and displayed.For files of audio data with a speed of bit variables.The audio data player (10) generates a map of the timing of play back after a competitor to play back and a fast forward scan data files of audio.A competitor to the play back, the sweep forward and reverse scan of the file of audio data.The audio data player (10) determines the ratio of compression to each portion of the data covered, and calculates the time to play back to each portion of the data covered.
