Method and apparatus for incorporating additional audio information into audio data file identifying information
First Claim
1. In a data device having a user interface including an audio output and a user input, a method of processing an audio data file, comprising the steps of:
- selecting and retrieving an audio data file for playback in response to a user input;
identifying audio tag information associated with the selected audio data file, the audio tag information including an audible announcement of an attribute of the associated audio data file;
decoding and processing the audio data file to provide an audible output; and
decoding and processing the audio tag information to provide the audible announcement of the attribute of the selected audio data file in response to a user input.

Abstract
A digital audio player (10) and a method for processing encoded digital audio data. The audio data player has 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 (32). The data structure generally includes a first audio data file having an information segment and an audio data segment. The information segment, generally called a tag, may include textual and graphic information related to the audio data segment. The present invention further includes an additional data frame in the information segment storing one or more audio data files, or “audio tag files”. The audio tag files stored in the information segment include encoded audible or voice recordings that vocalize other tag information related to the audio data segment. The informational audio tag files can be created by processing textual tag information with a text-to-voice converter, or by downloading the informational audio tag files from a server or the Internet. To prevent a data processing device, from inadvertently recognizing the informational audio tag files as stand-alone audio data files, the data structure of the audio tag files may be altered prior to storage in the audio data file.

7. A method of associating audio tag voice files with an audio data file, comprising the steps of:
-
receiving an audio tag voice file that is encoded in the same format as the audio data file;
altering the data structure of the encoded audio tag voice file; and
storing the altered audio tag voice file into an identifying information portion of the audio data file. - View Dependent Claims (8, 9, 10)

11. An audio data player, comprising:
-
a data storage device for storing a plurality of audio data files;
a digital signal processor for decoding a selected audio data file to provide an output signal;
user input for accepting user input commands; and
a microcontroller, coupled to the data storage device, the digital signal processor, and the user input, for causing a selected audio data file to be decoded, processed, and provided to an output device in response to user input, the microcontroller adapted to identify an audio tag file included in an identifying information portion of the selected audio data file and cause the audio tag file to be decoded and processed in response to a user input. - View Dependent Claims (12, 13, 14, 15, 16)
