MP3 audio-book format

MP3 is most widely used sound player format. Almost all portable audio players and desktop media players are MP3-capable player. However, the format is not bookmark capable. For this reason many modern hand-held audio players will simulate a bookmark when the player is stopped and left to time-out till it powers itself down. In many cases the player saves its current state and restarts from the saved state after power-on. Most desktop software packages also allow the playing of the file to be restarted at any desired point. Under these conditions, MP3 is a still a highly useful format for audio books.
