Creating and Playing MP3/WMA Files
I Converting a music CD into MP3/WMA files
Creating MP3/WMA files by recording them from sources such as
broadcasts, records, recordings, videos and live performances without
permission from the copyright holder for uses other than personal
enjoyment is prohibited.
Prepare a computer and a commercially available MP3/WMA encoder
(conversion) software (some can be found for free on the Internet).
Load a music CD into the computer's CD-ROM drive and compress the
music CD by following the procedure of the MP3/WMA encoder
software. MP3/WMA-format music data files are created. A 12 cm music
CD (with a maximum of 74 minutes of recording/650 MB of data) can
be compressed to 65 MB (about 1/10 of the original size).
CAUTION
• To ensure stable sound quality during playback, we
recommend fixing the bit rate to 128 kbps and the sampling
frequency to 44.1 kHz.
• Note that it may not be possible to read some CD-R or
CD-RW discs, depending on their characteristics.
• There are many types of MP3/WMA encoding software
available, including commercial and freeware programs.
Depending on the encoder and the file format, the audio
quality may deteriorate, noise may be generated when
playing starts, or some recordings may not play.
• When files other than MP3/WMA files are recorded on a disc,
the system may take some time to recognize the disc and it
may not play.
I Writing MP3/WMA files on a CD-R/RW disc
MP3/WMA files can be recorded on a CD-R/RW disc by using a CD-R/
RW drive connected to a computer. Record by setting the recording
format of the recording software to ISO9660 level 1 or level 2 (not
including the extension format).
Select CD-ROM (mode 1) or CD-ROM XA (mode 2) as the disc format.
I Playing a CD-R/RW disc
Insert a CD-R/RW disc on which MP3/WMA files are recorded. When you
load a disc, the system automatically determines whether it is a music
CD or a CD-R/RW disc that contains MP3/WMA files, and plays it
correctly. However, note that depending on the type of disc being used,
the disc may not play.
I Downloading from MP3/WMA music sites on the
Internet
You can find various types of MP3/WMA music distribution sites on the
Internet, including online shopping, trial listening, and free download
sites. You can download music files from these sites by following their
payment and other downloading rules.
