Audio CDs

MP3 files

or

Audio data is converted to the ATRAC3plus/ATRAC3 format by the SonicStage Simple Burner.

How to use the SonicStage Simple Burner

Refer to the supplied booklet "SonicStage Simple Burner."

What is an ATRAC CD?

An ATRAC CD is a CD-R/RW on which audio data compressed in the ATRAC3plus/ATRAC3 format has been recorded. About 30 audio CDs can be recorded on a CD-R/RW.* You can also record MP3 files by converting the files to the ATRAC3plus/ATRAC3 format.

* When total playing time of one CD (album) is estimated at 60 minutes and you are recording on a 700 MB CD-R/RW at 48 kbps in ATRAC3plus format.

Step 3 Listen

You can enjoy listening to your own ATRAC CDs on your ATRAC CD Walkman.

What is the ATRAC3plus/ATRAC3 format?

Refer to pages 6 - 8 of this manual.

Music sources playable on this CD player

You can play the following 3 music sources on this CD player:

• Audio CDs • ATRAC3plus/ATRAC3 format files
• MP3 files

Usable disc formats

You can use ISO 9660 Level 1/2 and Joliet extension format discs only.

ATRAC3plus and ATRAC3

"ATRAC3plus," which stands for "Adaptive Transform Acoustic Coding3plus" is audio compression technology, developed from the ATRAC3 format. Though the ATRAC3plus format can compress music content to about 1/20 of its original size, you can still enjoy high quality sound. The available transfer bit rates are 64 kbps and 48 kbps.

"ATRAC3," which stands for "Adaptive Transform Acoustic Coding3" is audio compression technology that satisfies the demand for high sound quality and high compression rates. The ATRAC3 format can compress music content to about 1/10 of their original size, which contributes to reduction of the media volume. The available transfer bit rates are 132 kbps, 105 kbps and 66 kbps.

The usable number of groups and files

• Maximum number of groups: 255

• Maximum number of files: 999

For details, refer to the supplied booklet “SonicStage Simple Burner.”

Note on saving files on the media

Do not save files in other formats or unnecessary groups on a disc that has ATRAC3plus/ATRAC3 files.

MP3 files

MP3, which stands for MPEG-1 Audio Layer3, a standard for audio files compression supported by the Motion Picture Experts Group, an ISO (International Organization for Standardization) working group, enables compression of audio files to about 1/10 of the data size of a standard compact disc. Since the MP3 encoding algorithm is public, there are various encoders/decoders that are compliant with this standard, including freeware that is available for no charge. Thus, the MP3 standard is widely used in the computer field.

The major specifications of the acceptable disc format are:

• Maximum directory levels: 8 - Acceptable characters for a file/folder name:

A - Z, a - z, 0 - 9, _ (underscore)

Notes

• When naming files, be sure to add the file extension "mp3" to the file name.
• If you add the extension “mp3” to a file other than an MP3 file, the player will not be able to recognize the file properly.
• The file name does not correspond to the ID3 tag.

The usable number of groups and files

• Maximum number of groups: 100 • Maximum number of files: 400

Settings for compression and writing software

• This CD player supports MP3 files with the following specifications: transfer bit rate: 16 - 320 kbps and sampling frequencies: 32/44.1/48 kHz. Variable Bit Rate (VBR) is also supported. To compress a source for an MP3 file, we recommend setting the transfer bit rate of the compression software to "44.1 kHz," "128 kbps," and "Constant Bit Rate."
• To record up to the maximum capacity, set to "halting of writing."
• To record at one time up to the maximum capacity on media that has nothing recorded on it, set to "Disc at Once."

Notes on saving files on the media

• Do not save files in other formats or unnecessary folders on a disc that has MP3 files.
• When a disc is inserted, the CD player reads all the information of folders and files on that disc. If there are many folders on the disc, it may take a long time for play to begin or for the next file to start playback.

Difference between ATRAC3plus/ATRAC3 and MP3

Groups and folders

The ATRAC3plus/ATRAC3 format has a very simple structure. It consists of "files" and "groups." A "file" is equivalent to a "track" of an audio CD. A "group" is a bundle of files and is equivalent to an "album." A "group" has no directory-type structure (a new group cannot be made within an existing group). This CD player is designed to recognize an MP3 file folder as a "group" so that it can play CD-Rs/RWs recorded in both the ATRAC3plus/ATRAC3 format and those recorded in the MP3 format with the same operation.

Displaying the track name, etc.

When playing a CD having ATRAC3plus/ATRAC3 files or MP3 files on this CD player, track names, artist names and album names are displayed. This CD player conforms to Version 1.1/2.2/2.3 of the ID3 tag format*.

*ID3 tag is a format for adding certain information (track name, album name, artist name, etc.) to MP3 files.

Notes

• This CD player cannot record music content on recordable media, such as CD-Rs/RWs.
• CD-Rs/RWs recorded in the ATRAC3plus/ATRAC3 format cannot be played on your computer.
• Playback capability may vary depending on the quality of the disc and the condition of the recording device.

On headphones/earphones Road safety

Do not use headphones/earphones while driving, cycling, or operating any motorized vehicle. It may create a traffic hazard and is illegal in some areas. It can also be potentially dangerous to play your headsets at high volume while walking, especially at pedestrian crossings. You should exercise extreme caution or discontinue use in potentially hazardous situations.

Preventing hearing damage

Avoid using headphones/earphones at high volume. Hearing experts advise against continuous, loud and extended play. If you experience a ringing in your ears, reduce volume or discontinue use.

Consideration for others
