About MP3

An MP3 file is audio data compressed by using MPEG1, the audio layer-3 file- coding scheme. We call files that have the “.mp3” file extension “MP3 files.”

The player can not read an MP3 file that has a file extension other than “.mp3.”

Noises may be heard if you play a non- MP3 file that has the “.mp3” extension.

This unit can play up to 255 files per disc. A disc having more than 255 files cannot be played files.

This unit can also display up to 255 folders per disc on the TV screen. A disc having more than 255 folders cannot be displayed folders on the TV screen .

The unit may not play MP3 files in the order that you recorded them on the disc.

With a multi-session disc, the player plays the all session.

It may take over 30 seconds to read the MP3 files, depending on the contents of the disc.

Tips on recording MP3

To enjoy high quality sound, convert to MP3 files with a sampling frequency of 44.1kHz and a fixed bit rate of 128 kbps.

To play MP3 files in the order that you

recorded them

Writing software that is capable of recording MP3 files in numerical and alphabetical order is required.

Include a two or three digit number at the beginning of each file name. (e.g. “01,” “02,” ... or “001,” “002,” ...)

It’s recommended that you use only the root folder (do not create a child folder under the root folder).

Note

During MP3 playing back, the recorder does not output the audio signal via the DIGITAL OPTICAL OUT jack so the audio signal is outputted only via the ANALOG OUT (L/R) jacks.

Glossary

Extension:

An extension is the last three characters that divide a file name by a period. The extension shows the attribution of the file or the software in which the file was created.

Session:

A session is one section on a disc between the beginning of data and the end of written data.

A multi-session disc has more than two sessions.

Note

Depending on the state of MP3 recording, there may be sound skips and noise during playback.
