Listening to Audio CDs and MP3 Discs

MP3 files have been written.
MP3 discs
What are MP3 files?
MP3 (MPEG-1 Audio Layer 3) is the name of a standard for compressing audio data
that can be handled by computers. Audio data compressed by MP3 is called an MP3
file. The special feature of MP3 is its high compression rate, which lets you compress
one 12 cm audio CD (maximum 74 minutes running time/650 MB data capacity) into
about 65 MB of data.
MP3 data that can be played
• Only MP3 discs created in ISO9660 levels 1 and 2 multiple sessions,
Joliet, and Romeo formats can be played. MP3 discs created by the packet
write method cannot be played.
• Only files with an MP3 file compression bit rate of 192 kbps or less or a
fixed bit rate, and compression format MPEG 1/2, Layer 2/3, can be
played.
• Up to 300 files can be recognized. The 301st and subsequent files are not
recognized.
• MP3 files that can be played are MP3 format with an .MP3 or .mp3
extension.
• Up to 8 folder levels on a disc can be recognized. The 9th and subsequent
levels are not recognized.
Creating MP3 files
To create an MP3 file, you need extra encoder (or conversion) software. By
following the software procedure you can compress audio data from an
audio CD into an MP3 file.
